Product details
Overview
MAX16006ETG+T from Maxim Integrated is an octal-voltage microprocessor supervisor IC designed for multivoltage system monitoring in industrial and telecom infrastructure. It monitors eight independent supply rails (e.g., 5V, 3.3V, 1.8V, 1.2V, 0.9V), provides an active-low RESET output asserting on any undervoltage or manual reset, features a 140ms minimum internal reset timeout (capacitor-adjustable), and operates across –40°C to +125°C.
For engineers reviewing the MAX16006ETG+T datasheet, MAX16006ETG+T pinout, MAX16006ETG+T application, or MAX16006ETG+T equivalent, this page delivers verified electrical specifications, confirmed 24-pin TQFN package mapping, validated octal-monitoring architecture, watchdog timer integration with 1.6s timeout, and real-world use cases in storage controllers and server power sequencing.
Technical Context
The MAX16006ETG+T implements independent voltage comparators per input channel with programmable 5% or 10% threshold tolerance via the TOL pin, and guarantees correct logic state down to VCC = 1V. Its open-drain outputs include internal 30μA pullups, eliminating external resistors while supporting external drive up to 5.5V.
It integrates a watchdog timer with 1.6s typical timeout and 54s startup delay after reset assertion, disabled by leaving WDI floating. The SRT pin enables capacitor-based reset timeout adjustment from 140ms minimum to >3s, and MR/MARGIN pins support manual reset assertion and margin-test deassertion respectively.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Monitored Voltages | Eight independent inputs (IN1–IN8) with fixed thresholds (e.g., 5V/3.3V/1.8V/1.2V/0.9V) or adjustable down to 0.4V |
| Reset Timeout | 140ms minimum (internal), adjustable to >3s using external capacitor on SRT pin |
| Operating Temp | –40°C to +125°C - qualified for harsh industrial and telecom environments |
| Supply Voltage | VCC = 1.0V to 5.5V - ensures reliable operation during brownout conditions |
| Watchdog Timeout | 1.12s to 2.40s (typ 1.6s) with 54s startup delay after reset - prevents premature system boot |
| Input Threshold Accuracy | ±1.25% over temperature (e.g., 3.3V threshold = 3.053V min / 3.135V max at TOL = GND) |
| Quiescent Current | 45–70µA (VCC = 2.0–5.5V) - enables low-power always-on supervision |
Pinout & Package
MAX16006ETG+T is housed in a 24-pin 4mm × 4mm TQFN package (exposed pad, RoHS-compliant) with thermal performance optimized for high-reliability PCB layouts. Pin 24 (EP) must be soldered to ground plane for thermal dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1–IN8 | Monitored supply inputs | Eight independent analog inputs accepting 0.4V–5.5V; each triggers dedicated fault detection |
| RESET | Active-low system reset output | Open-drain output asserting when any INx falls below threshold or MR is pulled low; internal 30µA pullup |
| MR | Manual reset input | Active-low input with 20kΩ internal pullup; asserts RESET for full timeout after release |
| MARGIN | Margin test disable control | Active-low input forcing all outputs high during voltage margining without affecting monitored rails |
| TOL | Threshold tolerance select | Logic-high selects ±10% threshold accuracy; logic-low selects ±5% - sets comparator hysteresis |
| SRT | Reset timeout timing input | Connect external capacitor to GND to set timeout; connect to VCC for fixed 140ms minimum |
| WDI | Watchdog timer input | Edge-sensitive input; watchdog resets on rising/falling edge; floating disables timer |
| VCC | IC supply input | Unmonitored 1.0–5.5V supply; requires 0.1µF bypass capacitor to GND |
| GND | Ground reference | Primary signal and power return; EP (pin 24) is electrically tied to GND |
Key Features
| Feature | Design Value |
|---|---|
| Octal independent monitoring | Simultaneous supervision of eight distinct supply rails with no shared thresholds or propagation delays |
| Capacitor-adjustable reset timeout | Enables precise system-level power-up sequencing control beyond fixed 140ms baseline |
| Integrated watchdog with startup delay | 54s initial window prevents false timeout during BIOS/post-boot initialization phases |
| Internal 30µA pullups on all outputs | Eliminates need for 8 external pullup resistors - reduces BOM count and layout area |
| Margin enable function | Allows safe voltage stress testing without disrupting system reset behavior or triggering false faults |
| Guaranteed operation down to VCC = 1V | Ensures deterministic reset assertion during deep brownout or battery-depleted conditions |
Applications
| Storage Equipment | Servers |
|---|---|

IC Role / Device Role / Timing Role: Centralized reset generator with independent monitoring per rail and manual reset override for service access. Use Value: Enables hot-swap PSU validation and graceful shutdown via MARGIN-controlled deassertion during maintenance. |
| Networking Equipment | Multivoltage ASICs |
Use Scenario: Power sequencing and fault detection in 10G/25G Ethernet line cards and packet processors. IC Role / Device Role / Timing Role: Real-time voltage supervisor interfacing with FPGA-based management controllers via RESET and WDI signals. Use Value: Detects transient rail collapse during burst traffic, triggering watchdog reset before packet loss escalates into link failure. | Use Scenario: Validating stable biasing of mixed-signal blocks (ADC, PLL, I/O) in custom ASICs during bring-up and production test. IC Role / Device Role / Timing Role: Precision threshold monitor with ±5% accuracy (TOL = GND) for process/voltage/temperature corner validation. Use Value: Confirms rail stability within 100mV of nominal before releasing ASIC from reset - avoids metastability in clock domains. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage supervisor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX16007ETG+ | Same octal monitoring, identical pinout and electrical specs; differs only in factory-programmed threshold configuration (MAX16007F supports 5V/3.3V/3.0V/2.5V/1.8V/1.5V/1.2V/0.9V fixed set) | No functional difference in circuit design; MAX16007ETG+ offers preconfigured 0.9V–5V thresholds vs. MAX16006ETG+'s broader ADJ/fixed mix | Select MAX16007ETG+ if exact 0.9V–5V rail set is required; otherwise MAX16006ETG+ provides greater flexibility with six ADJ-capable inputs |
| TPS3808G33DBVR | Single-supply supervisor (one input), no watchdog, no margin enable, 3.3V fixed threshold only; 6-pin SOT-23 package | Only suitable for single-rail systems; lacks octal capability, independent outputs, and advanced features like SRT/MARGIN | Use only for cost-sensitive, single-rail applications where full MAX16006ETG+ functionality is unnecessary |
Compared with MAX16007ETG+, the MAX16006ETG+ offers configurable threshold assignment across all eight inputs, while TPS3808G33DBVR serves only basic single-rail monitoring - making MAX16006ETG+ the sole fit for complex multivoltage sequencing with watchdog and margining support.

FAQ
What is the function of the MARGIN pin on the MAX16006ETG+T?
The MARGIN pin on the MAX16006ETG+T is an active-low input that forces all output signals (including RESET) into a high-impedance or deasserted state during voltage margin testing. When pulled low, it overrides all voltage-monitoring fault conditions without affecting the actual monitored rails - enabling safe stress testing of power supplies while keeping the system in a known operational state. This function is critical for validating ASIC or FPGA power integrity under worst-case voltage corners.
Does the MAX16006ETG+T support adjustable reset timeout, and how is it configured?
Yes, the MAX16006ETG+T supports adjustable reset timeout via the SRT pin. Connecting an external capacitor between SRT and GND sets the timeout period using the formula tRP = 2.06 × 10⁶ Ω × CSRT (F); for example, a 1500pF capacitor yields ~3.09ms. Leaving SRT unconnected or tying it to VCC selects the internal 140ms minimum timeout. This configurability allows precise alignment with system power-up sequencing requirements across diverse board designs.
What is the watchdog timer behavior of the MAX16006ETG+T, and how is it disabled?
The MAX16006ETG+T watchdog timer has a 1.6s typical timeout period and a 54s startup delay after RESET assertion. It clears on any rising or falling edge at the WDI pin and asserts RESET if WDI remains static beyond timeout. To disable the watchdog, leave the WDI pin unconnected - its internal open-state detector draws only 400nA, ensuring no unintended activation. This behavior is confirmed in the device's Electrical Characteristics table and Pin Description section.
Can the MAX16006ETG+T monitor voltages below 1.0V, and what is the lowest supported threshold?
Yes, the MAX16006ETG+T can monitor voltages as low as 0.4V using its adjustable threshold mode. When the TOL pin is tied to VCC, the minimum detectable input voltage is 0.366V (typ), and when TOL = GND, it is 0.388V (typ). This capability is explicitly specified in the Electrical Characteristics table under "Adjustable Threshold (IN_ Falling)" and enables supervision of modern sub-1V core rails in FPGAs and AI accelerators.
What package type and footprint does the MAX16006ETG+T use, and is thermal pad connection required?
The MAX16006ETG+T uses a 24-pin TQFN package measuring 4mm × 4mm with an exposed thermal pad (EP, pin 24). The EP is internally connected to GND and must be soldered to the PCB ground plane to ensure proper thermal dissipation and junction temperature control. Land Pattern Number 90-0022 applies, and failure to connect EP may result in exceeding the +150°C maximum junction temperature under sustained load.
