Product details
Overview
MAX16006FTG+ from Maxim Integrated is an octal-voltage microprocessor supervisor IC designed for complex multivoltage systems. It monitors eight independent supply rails (e.g., 5V, 3.3V, 2.5V, 1.8V, 1.5V, 1.2V, 0.9V, and adjustable down to 0.4V), provides an active-low RESET output asserting on any undervoltage or manual reset, features a 140ms minimum reset timeout (capacitor-adjustable), and operates across –40°C to +125°C in a 24-pin TQFN package.
For engineers reviewing the MAX16006FTG+ datasheet, MAX16006FTG+ pinout, MAX16006FTG+ application, or MAX16006FTG+ equivalent, this page delivers verified electrical specifications, confirmed pin functions, real-world use cases in servers and storage equipment, and validated alternative parts with documented functional differences.
Technical Context
The MAX16006FTG+ implements independent voltage monitoring per input channel with fixed or adjustable thresholds selected via the TOL pin (5% or 10% tolerance). Its RESET output asserts whenever any of the eight monitored voltages falls below its threshold or MR is pulled low, and remains asserted for the full reset timeout after all inputs recover and MR is released.
It includes a watchdog timer with 1.6s typical timeout and 54s startup delay, disabled by leaving WDI floating. All open-drain outputs (RESET, OUT1–OUT8) feature internal 30µA pullups, eliminating external resistors while supporting external drive up to 5.5V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Monitored Voltages | Eight independent inputs (IN1–IN8), configurable for fixed thresholds (5V/3.3V/3V/2.5V/1.8V/1.5V/1.2V/0.9V) or adjustable down to 0.4V |
| Reset Timeout | 140ms minimum (internally set); adjustable up to seconds via external capacitor on SRT pin |
| Operating Temperature | –40°C to +125°C - fully specified for automotive-grade and industrial embedded environments |
| Supply Voltage Range | VCC = 1.0V to 5.5V - guaranteed correct logic state down to VCC = 1V |
| Watchdog Timeout | 1.12s to 2.40s (typ 1.6s), with 35–72s startup delay after reset assertion |
| Output Type | Open-drain RESET and eight independent OUTx outputs, each with internal 30µA pullup to VCC |
| Threshold Accuracy | ±1.5% over temperature for fixed thresholds (e.g., 3.3V ±1.5% at –40°C to +125°C) |
Pinout & Package
MAX16006FTG+ is housed in a 24-pin TQFN package (4mm × 4mm, 0.5mm pitch) with exposed pad (EP) internally connected to GND. The package supports high-density PCB layouts and efficient thermal dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1–4, 21–24 | IN5–IN8 / IN1–IN4 | Eight monitored voltage inputs; each compares against programmable threshold and triggers corresponding OUTx or RESET |
| 5, 6 | WDI, GND | Watchdog timer input (edge-sensitive, 400nA bias); GND reference for all circuitry and thermal path via EP |
| 7, 13 | VCC, SRT | Unmonitored power supply input (1.0–5.5V); SRT sets reset timeout via external capacitor (140ms min when tied to VCC) |
| 8–11 | OUT5–OUT8 | Open-drain outputs asserting low when respective IN5–IN8 fall below threshold; 30µA internal pullup eliminates external resistors |
| 12, 14 | MR, MARGIN | Active-low manual reset (20kΩ internal pullup); active-low margin disable forcing all outputs high during testing |
| 15–18 | OUT4–OUT1 | Open-drain outputs for IN4–IN1; identical behavior to OUT5–OUT8 with same internal pullup and drive capability |
| 19, 20 | RESET, IN1 | Active-low system reset output (asserted on any fault or MR); IN1 is first monitored rail (configurable per variant) |
| 24 | TOL | Threshold tolerance select: GND = ±5%, VCC = ±10% - enables design flexibility across production tolerances |
Key Features
| Feature | Design Value |
|---|---|
| Octal independent voltage monitoring | Enables single-chip supervision of eight distinct power domains (e.g., CPU core, I/O, memory, PHY, auxiliary rails) |
| Capacitor-adjustable reset timeout | Supports precise system-level power sequencing timing without firmware dependency or fixed-timer limitations |
| Internal 30µA pullups on all outputs | Reduces BOM count and layout area by eliminating eight external pullup resistors while maintaining noise immunity |
| Manual reset with 20kΩ internal pullup | Eliminates need for external MR pullup resistor; ensures reliable reset initiation even with weak host GPIO drivers |
| Margin enable function | Allows safe deassertion of all outputs during factory margin testing without altering power supply settings or risking false resets |
| Guaranteed operation down to VCC = 1V | Ensures correct supervisory behavior during brown-out conditions and ultra-low-power wake-up sequences |
Applications
| Storage Equipment | Servers |
|---|---|
Use Scenario: Monitoring multiple voltage rails in NVMe SSD controllers and SAS/SATA backplanes where 12V, 5V, 3.3V, 1.8V, and 1.2V supplies must sequence correctly and remain stable under load. IC Role / Device Role / Timing Role: Octal supervisor providing independent fault detection per rail and coordinated system reset via shared RESET output. Use Value: Prevents data corruption and controller lockup by asserting RESET before any rail violates specification, with 140ms timeout ensuring sufficient hold time for power stabilization. | Use Scenario: Supervising complex multivoltage motherboard designs in 1U/2U rack servers, including CPU VDD, memory VDDQ, PCIe switch rails, BMC supplies, and fan controller voltages. IC Role / Device Role / Timing Role: Centralized voltage health monitor with watchdog integration, enabling BIOS/firmware to detect both power faults and software hangs. Use Value: Reduces component count versus discrete supervisors; 1.6s watchdog timeout aligns with server boot-time diagnostics windows without premature reset. |
| Networking Equipment | Multivoltage ASICs |
Use Scenario: Power supervision in 10G/25G Ethernet switches and routers where PHY, SerDes, MAC, and management processor rails require simultaneous monitoring and coordinated reset. IC Role / Device Role / Timing Role: Fault-detection hub feeding RESET to FPGA-based control logic and asserting watchdog timeout if firmware stalls during link training. Use Value: Eliminates need for separate reset generators and watchdog ICs; TOL pin allows ±5% threshold tuning to match ASIC vendor's recommended supply tolerances. | Use Scenario: Ensuring clean power-up and runtime stability for high-performance ASICs with >8 dedicated supply domains (e.g., core logic, analog PHY, PLL, I/O, memory interface). IC Role / Device Role / Timing Role: Precision rail monitor with adjustable thresholds (down to 0.4V) for custom low-voltage domains and margin test support via MARGIN pin. Use Value: Enables ASIC vendors to specify exact threshold values per rail; internal pullups reduce routing congestion in dense BGA packages. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage supervisor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX16007ATJ+ | Same octal monitoring, identical pinout and electrical specs; differs only in factory-programmed threshold configuration (MAX16007F uses 5V/3.3V/3V/2.5V/1.8V/1.5V/1.2V/0.9V set) | No functional difference in server/storage use; MAX16007F matches legacy board designs requiring fixed 0.9V rail monitoring | Select MAX16007ATJ+ only if the exact 0.9V threshold is required and MAX16006FTG+'s adjustable IN8 does not meet spec |
| TPS3808G33DBVR | Quad supervisor (not octal); 3.3V fixed threshold only; no watchdog; 200ms fixed reset timeout; SOT-23-6 package | Cannot replace MAX16006FTG+ in multirail systems; suitable only for simple 3.3V-only applications with minimal footprint constraints | Use only for cost-sensitive, single-rail designs where octal monitoring and watchdog are unnecessary |
Compared with MAX16007ATJ+, MAX16006FTG+ offers greater flexibility via adjustable thresholds on all eight inputs, while TPS3808G33DBVR lacks scalability for systems requiring more than four rails or advanced features like watchdog or margin enable.

FAQ
What is the maximum number of voltage rails monitored by the MAX16006FTG+?
The MAX16006FTG+ monitors eight independent voltage rails (IN1 through IN8). Each input supports either factory-configured fixed thresholds (e.g., 5V, 3.3V, 2.5V, 1.8V, 1.5V, 1.2V, 0.9V) or user-adjustable thresholds down to 0.4V, making it suitable for highly segmented power architectures found in modern ASICs and servers.
Does the MAX16006FTG+ include a watchdog timer, and how is it configured?
Yes, the MAX16006FTG+ includes a watchdog timer with a typical timeout of 1.6s (range 1.12s to 2.40s) and a 54s startup delay after reset. It is enabled by connecting WDI to a toggling signal; leaving WDI unconnected disables the timer. The watchdog asserts RESET if no edge is detected within the timeout window, and clears on any rising or falling edge.
How is the reset timeout period set on the MAX16006FTG+?
The reset timeout on the MAX16006FTG+ is set using the SRT pin. Connecting SRT to VCC yields a minimum 140ms timeout. For longer durations, a capacitor is connected from SRT to GND; timeout (seconds) = 2.06 × 10⁶ Ω × C (farads). This allows precise, hardware-based timing without firmware intervention or external RC components beyond the capacitor.
What is the purpose of the MARGIN pin on the MAX16006FTG+?
The MARGIN pin on the MAX16006FTG+ is an active-low input that forces all eight OUTx outputs and RESET into a high (deasserted) state when pulled low. This enables safe margin testing - intentionally perturbing supply voltages while preventing spurious resets - without modifying power supply settings or requiring system-level software coordination.
Can the MAX16006FTG+ operate reliably at low VCC levels, and what is its minimum functional supply voltage?
Yes, the MAX16006FTG+ guarantees correct logic state operation down to VCC = 1.0V, as confirmed in the Absolute Maximum Ratings and Electrical Characteristics tables. This ensures robust behavior during brown-out conditions, battery-backed backup modes, and ultra-low-power wake-up sequences common in industrial and telecom systems.
