Product details
Overview
MAX6717AUKWGD3+T from Maxim Integrated is a dual-supply ultra-low-voltage microprocessor supervisory circuit in 6-pin SOT23 package, monitoring VCC1 (primary) and VCC2 (secondary) with factory-trimmed reset thresholds of 4.625V (VTH1) and 3.075V (VTH2), 280ms minimum reset timeout, open-drain active-low RST output, and manual-reset input - used to ensure reliable boot and brownout recovery in telecom power systems.
For engineers reviewing the MAX6717AUKWGD3+T datasheet, MAX6717AUKWGD3+T pinout, MAX6717AUKWGD3+T application, or MAX6717AUKWGD3+T equivalent, key selection criteria include dual-supply monitoring capability down to 0.8V supply validity, guaranteed reset assertion during VCC1/VCC2 undervoltage, low 15µA typical supply current at 3.6V, and compatibility with -40°C to +125°C industrial operating environments.
Technical Context
The MAX6717AUKWGD3+T implements independent voltage comparators for VCC1 and VCC2, each referenced to precision internal bandgap references, with hysteresis of 0.5% and tempco of 20ppm/°C. Reset assertion occurs when either supply falls below its threshold and remains asserted for a fixed 280ms (min) timeout after both supplies recover.
It features an internal 50kΩ pullup on MR, supports CMOS-level manual reset triggering with 1µs minimum pulse width, and guarantees valid reset logic state as long as VCC1 or VCC2 ≥ 0.8V - enabling robust operation during deep brownout conditions without external support circuitry.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC1 Reset Threshold | 4.625V (typ), factory-trimmed for precise 4.5–4.75V primary supply monitoring |
| VCC2 Reset Threshold | 3.075V (typ), factory-trimmed for accurate 3.0–3.15V secondary supply monitoring |
| Reset Timeout Period | 280ms (min), ensures sufficient hold time for processor initialization and memory stabilization |
| Supply Current | 15µA (typ) at 3.6V, enabling battery-backed and low-power always-on supervision |
| Operating Temperature | -40°C to +125°C, qualified for automotive under-hood and industrial control applications |
| Reset Output Type | Open-drain active-low RST, requires external pullup for system-level reset signaling |
| MR Input Pullup | 50kΩ internal resistor to VCC1, eliminates need for external bias in manual-reset implementations |
Pinout & Package
MAX6717AUKWGD3+T is housed in a 6-pin SOT23-6 package (package code U6+1), with 1.6mm × 2.9mm footprint and 1.1mm height, optimized for space-constrained PCB layouts in telecom and embedded systems.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | RST / RST1 | Active-low open-drain reset output; asserts low when VCC1 or VCC2 drops below threshold or MR is pulled low; requires external pullup |
| 2 | GND | Ground reference for all internal comparators, timers, and output drivers |
| 3 | MR | Active-low manual-reset input with internal 50kΩ pullup to VCC1; initiates reset on logic-low transition |
| 4 | VCC2 | Secondary supply input (0.8V–5.5V); powers internal circuitry when above VCC1 and sets VCC2 reset threshold |
| 5 | VCC1 | Primary supply input (0.8V–5.5V); powers device when above VCC2 and defines main reset threshold and output reference |
| 6 | - | No connection (NC); unused pin per MAX6717A variant pinout |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent supply monitoring | Simultaneous VCC1 and VCC2 supervision with separate thresholds avoids single-point failure in multirail systems |
| Guaranteed reset validity down to 0.8V | Ensures correct reset assertion even during severe brownout, eliminating need for external undervoltage lockout |
| Low 15µA supply current | Minimizes standby power draw in battery-powered or energy-sensitive applications like remote sensors |
| Immunity to short VCC transients | Rejects <20µs glitches below reset threshold, preventing spurious resets in noisy power environments |
| Factory-trimmed precision thresholds | ±1.25% tolerance on VTH1/VTH2 eliminates calibration overhead and improves BOM consistency |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-supply supervisory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6717AUTTWD3+T | Same electrical specs but in 5-pin SOT23-5 package; lacks NC pin; identical VTH1/VTH2 and 280ms timeout | Used where board space is more constrained and no future pin expansion needed | Select when minimizing footprint is critical and 6-pin routing complexity must be avoided |
| TLV809E46DBZR | Single-supply 4.6V supervisor (SOT23-3), no VCC2 monitoring, no MR input, 200ms timeout, 1.8µA ICC | Suitable only for basic single-rail systems without secondary supply or manual reset requirement | Choose only for cost-sensitive, single-voltage applications where dual monitoring is unnecessary |
Compared with MAX6717AUTTWD3+T, the MAX6717AUKWGD3+T offers identical supervision functionality with added layout flexibility via the NC pin; versus TLV809E46DBZR, it delivers true dual-rail fault detection and manual reset capability essential for complex embedded systems.

FAQ
What is the reset timeout period for MAX6717AUKWGD3+T?
The MAX6717AUKWGD3+T has a fixed minimum reset timeout period of 280ms (D5 suffix). This duration is guaranteed over the full -40°C to +125°C operating range and ensures sufficient time for microprocessor initialization, memory self-test, and peripheral configuration before release from reset. The actual timeout may vary slightly due to process and temperature but remains ≥280ms under all specified conditions.
Does MAX6717AUKWGD3+T support manual reset functionality?
Yes, MAX6717AUKWGD3+T includes an active-low manual-reset input (MR) with an internal 50kΩ pullup resistor to VCC1. Driving MR low for ≥1µs forces an immediate reset assertion, which remains active for the full 280ms timeout period after MR returns high. This enables hardware-initiated recovery without software intervention, critical for field service and test modes.
What are the absolute maximum supply voltage ratings for MAX6717AUKWGD3+T?
MAX6717AUKWGD3+T supports VCC1 and VCC2 inputs from -0.3V to +6V absolute maximum. However, functional operation is specified only from 0.8V to 5.5V per supply. The device guarantees valid reset output logic state as long as either VCC1 or VCC2 remains ≥0.8V - a key feature enabling robust brownout response without auxiliary supply rails.
Can MAX6717AUKWGD3+T monitor three supply voltages?
No, MAX6717AUKWGD3+T is a dual-supply supervisor monitoring only VCC1 and VCC2. It does not include RSTIN, WDI, PFI, or PFO pins - features present in other variants like MAX6719A or MAX6728A. The MAX6717AUKWGD3+T pinout omits these terminals, confirming its dedicated two-rail function without auxiliary monitoring capability.
What is the reset output type and drive capability of MAX6717AUKWGD3+T?
MAX6717AUKWGD3+T provides an open-drain active-low RST output (pin 1). It sinks ≥1.2mA at VCC1 ≥2.7V with VOL ≤0.3V, requiring an external pullup resistor to VCC1 or another logic rail. This configuration allows wired-OR reset bus sharing and voltage-level translation, making it compatible with diverse microprocessor reset input architectures.
