Product details
Overview
The MAX16000ETC+ from Maxim Integrated is a low-voltage, quad-voltage microprocessor supervisor IC in a 12-pin TQFN (4mm × 4mm) package. It monitors four independent supply rails-3.3V, 2.5V, adjustable, and 1.8V-with fixed or user-selectable 5%/10% threshold tolerance, delivers independent open-drain outputs with internal 30µA pullups, and provides a minimum 140ms reset timeout. It is designed for multivoltage ASIC power sequencing and fault detection in industrial servers.
For engineers reviewing the MAX16000ETC+ datasheet, MAX16000ETC+ pinout, MAX16000ETC+ application, or MAX16000ETC+ equivalent, key selection criteria include its quad-rail monitoring capability, capacitor-adjustable reset timeout, manual reset and margin enable inputs, guaranteed operation down to VCC = 1V, and AEC-Q100 qualification (for specific variants only).
Technical Context
The MAX16000ETC+ implements independent voltage monitoring per input channel with hysteresis (0.5% of threshold), supports both fixed thresholds (3.3V/2.5V/1.8V) and adjustable thresholds down to 0.4V via external resistor divider, and uses an internal SRT ramp current (460–740nA) and threshold (1.173–1.293V) to set reset timeout duration. Its logic remains valid down to VCC = 1V, enabling robust supervision during brownout conditions.
All outputs are open-drain with integrated 30µA pullups, eliminating external resistors while allowing external drive up to 5.5V; the MARGIN input enables active deassertion of all outputs during system margin testing, and the TOL pin selects between ±5% or ±10% threshold accuracy without external components.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Monitored Voltages | Four independent rails: 3.3V, 2.5V, adjustable (down to 0.4V), and 1.8V - enables simultaneous supervision of core, I/O, and analog supplies |
| Reset Timeout | Min 140ms (internally set); adjustable up to ~3.92ms with external capacitor - ensures reliable processor reset hold time across temperature |
| Supply Voltage Range | VCC = 1.0V to 5.5V - guarantees correct logic state even during deep brownout, supporting low-power SoC designs |
| Threshold Tolerance | Selectable 5% (TOL = GND) or 10% (TOL = VCC) - simplifies BOM by accommodating varying supply tolerances without redesign |
| Output Type | Open-drain with internal 30µA pullup - eliminates need for external pullup resistors and reduces board space and component count |
| Operating Temp | -40°C to +125°C - qualified for under-hood automotive and industrial embedded environments |
| Package | 12-pin TQFN, 4mm × 4mm, exposed pad - enables high thermal performance and compact layout in space-constrained systems |
Pinout & Package
Package: 12-pin TQFN (4mm × 4mm), exposed pad (EP) internally connected to GND. Requires thermal connection to PCB ground plane for optimal junction-to-ambient thermal resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 10, 11 | IN1–IN4 | Monitored voltage inputs for 3.3V, 2.5V, adjustable, and 1.8V rails - each triggers dedicated output on undervoltage |
| 3 | GND | Ground reference and thermal path via exposed pad - must be soldered to large copper area for thermal management |
| 4 | VCC | Unmonitored bias supply (1.0–5.5V) - requires local 0.1µF bypass capacitor to GND |
| 5, 6, 9, 12 | OUT1–OUT4 | Independent open-drain outputs - assert low when corresponding INx falls below threshold; 30µA internal pullup avoids external resistors |
| 7 | MARGIN | Active-low margin disable - pulls all OUTx high regardless of input status, enabling safe voltage margining during test |
| 8 | TOL | Threshold tolerance select - GND = ±5%, VCC = ±10%; sets hysteresis and accuracy without external components |
| 12 | TOL | Shared pin with OUT4 - function determined by part variant; for MAX16000ETC+, pin 12 is TOL (see Pin Configurations, p.8) |
Key Features
| Feature | Design Value |
|---|---|
| Quad independent voltage monitors | Enables discrete fault isolation across four critical rails - no shared reset assertion masking individual rail failures |
| Capacitor-adjustable reset timeout | Supports precise timing control (140ms to >3ms) via single external capacitor - replaces fixed RC networks with scalable solution |
| Internal 30µA output pullups | Reduces bill-of-materials count and PCB footprint - eliminates four external pullup resistors without compromising drive strength |
| Margin Enable function | Allows full-system voltage margin testing without modifying hardware - deasserts all outputs synchronously on command |
| Guaranteed operation down to VCC = 1V | Ensures reliable supervision during severe brownout or battery sag - maintains correct logic state where many supervisors fail |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad-voltage supervisor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX16001ETC+ | Includes watchdog timer (1.6s timeout) and shared RESET output; same pinout and monitoring capability | Required where system-level watchdog supervision is needed alongside quad-rail monitoring | Select MAX16001ETC+ if watchdog functionality is mandatory; otherwise MAX16000ETC+ offers simpler timing behavior and lower quiescent current |
| TPS3808G33DBVR | Triple-supervisor (not quad); fixed 3.3V threshold only; no adjustable inputs or margin enable | Limited to three-rail systems with standard 3.3V/2.5V/1.8V monitoring; no support for custom or sub-1.8V rails | Choose TPS3808G33DBVR only for cost-sensitive, triple-rail applications where adjustable thresholds and margin testing are unnecessary |
Compared with MAX16001ETC+, the MAX16000ETC+ omits the watchdog timer, reducing complexity and quiescent current (45–65µA vs. higher), while retaining identical quad-monitoring, margin enable, and capacitor-adjustable reset - making it optimal for deterministic, non-watchdog multivoltage systems.

FAQ
What is the exact pin configuration for MAX16000ETC+?
The MAX16000ETC+ uses a 12-pin TQFN package (4mm × 4mm) with top-view pinout: Pin 1 = IN1 (3.3V), Pin 2 = IN2 (2.5V), Pin 3 = GND, Pin 4 = VCC, Pin 5 = OUT1, Pin 6 = OUT2, Pin 7 = MARGIN, Pin 8 = TOL, Pin 9 = OUT3, Pin 10 = IN3 (adjustable), Pin 11 = IN4 (1.8V), Pin 12 = OUT4. The exposed pad (EP) is internally connected to GND and must be soldered to PCB ground.
Does MAX16000ETC+ include a watchdog timer?
No, the MAX16000ETC+ does not include a watchdog timer. Watchdog functionality is present only in MAX16001/MAX16002/MAX16004–MAX16007 variants. The MAX16000ETC+ provides pure quad-voltage supervision with independent outputs, manual reset, margin enable, and capacitor-adjustable reset timeout - making it ideal for applications requiring deterministic reset behavior without watchdog overhead.
What are the fixed voltage thresholds supported by MAX16000ETC+?
The MAX16000ETC+ supports fixed thresholds of 3.3V (IN1), 2.5V (IN2), and 1.8V (IN4), with IN3 configured as adjustable (0.4V–5.5V range). Threshold accuracy is selectable via the TOL pin: ±5% when tied to GND, ±10% when tied to VCC. Hysteresis is 0.5% of the threshold voltage, ensuring noise immunity during rail transitions.
How is the reset timeout period set on MAX16000ETC+?
The reset timeout on MAX16000ETC+ is set using the SRT pin (pin 8 in MAX16001/MAX16002, but note: MAX16000ETC+ does not have SRT - its timeout is fixed at ≥140ms). Unlike variants with SRT, the MAX16000ETC+ uses an internal timeout circuit only; no external capacitor is supported. For adjustable timeout, consider MAX16001ETC+ or MAX16002ETC+ instead.
Is MAX16000ETC+ qualified for automotive applications?
The MAX16000ETC+ itself is not AEC-Q100 qualified. AEC-Q100 qualification applies only to specific variants: MAX16001ATE/V+ and MAX16001DTE/V+. However, the MAX16000ETC+ operates over -40°C to +125°C and meets industrial reliability requirements, making it suitable for under-chassis industrial and telecom applications where full automotive qualification is not mandated.
