Product details
Overview
The MAX6717AUKVHD3+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 - specifically 4.625V (±125mV) for VCC1 and 3.075V (±75mV) for VCC2 - and featuring open-drain active-low RST output, manual-reset input (MR), and 140ms minimum reset timeout period. It ensures reliable system reset during brownout conditions in battery-powered telecom and industrial embedded systems.
For engineers reviewing the MAX6717AUKVHD3+T datasheet, MAX6717AUKVHD3+T pinout, MAX6717AUKVHD3+T application, or MAX6717AUKVHD3+T equivalent, key selection criteria include dual-rail voltage monitoring capability down to 0.8V supply validity, guaranteed reset assertion timing under transient conditions, low 15µA typical supply current at 3.6V, and compatibility with -40°C to +125°C extended temperature operation.
Technical Context
This device implements independent dual-voltage comparators with internal reference trimming, asserting reset when either VCC1 falls below 4.625V or VCC2 drops below 3.075V, with 0.5% typical hysteresis and 20µs propagation delay from threshold crossing to RST assertion. The reset output remains asserted for a fixed 140ms (min) timeout after both supplies recover above their respective thresholds.
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 even when VCC1 or VCC2 drops to 0.8V - enabling robust operation during deep brownout events without external support circuitry.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC1 Reset Threshold | 4.625V ±125mV - factory-trimmed for precise primary supply monitoring at 4.63V nominal |
| VCC2 Reset Threshold | 3.075V ±75mV - factory-trimmed for secondary supply monitoring at 3.08V nominal |
| Reset Timeout Period | 140ms (min) - ensures sufficient hold time for processor initialization after power recovery |
| Supply Current | 15µA (typ) at 3.6V - enables multi-year battery life in portable equipment |
| Operating Temperature | -40°C to +125°C - qualified for automotive under-hood and industrial control environments |
| Reset Output Type | Active-low open-drain - allows flexible voltage-level translation and wired-OR reset bus implementation |
| Minimum Valid Supply | VCC1 or VCC2 ≥ 0.8V - guarantees correct reset state during deep undervoltage conditions |
Pinout & Package
MAX6717AUKVHD3+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 portable and industrial applications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | RST/RST1 | Active-low open-drain reset output - asserts low on VCC1/VCC2 undervoltage; requires external pullup |
| 2 | GND | Ground reference for all internal comparators and logic |
| 3 | MR | Active-low manual-reset input - internally pulled up to VCC1; triggers reset when pulled low |
| 4 | VCC2 | Secondary supply input - powers internal circuitry when > VCC1 and sets VCC2 monitoring threshold |
| 5 | VCC1 | Primary supply input - powers device when > VCC2 and defines main reset threshold reference |
| 6 | NC | No connect - unused pin; must be left floating or grounded per layout best practice |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent voltage monitoring | Simultaneous supervision of VCC1 (1.8–5.0V) and VCC2 (0.9–3.3V) with separate thresholds and hysteresis |
| Immunity to short VCC transients | Rejects glitches <20µs duration at 100mV overdrive - prevents spurious resets in noisy power environments |
| Low-power operation | 15µA typical ICC1 at 3.6V - reduces quiescent load on battery or energy-harvesting supplies |
| Guaranteed reset validity down to 0.8V | Ensures deterministic reset behavior during deep brownout, eliminating need for external undervoltage lockout |
| Manual-reset integration | Internal 50kΩ MR pullup eliminates external resistor; supports momentary switch interface without debounce |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-supply supervisory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6715AUKTVD3+T | Same 6-pin SOT23 package but with 4.375V VCC1 threshold and 2.925V VCC2 threshold; identical 140ms timeout and open-drain RST | Suitable for systems requiring tighter margin on 4.5V nominal rails; lower thresholds reduce false trips on ripple-limited supplies | Select when primary supply nominal is 4.5V rather than 5.0V, and secondary is 3.0V instead of 3.3V |
| TPS3808G12QDBVRQ1 | Single-supply supervisor (monitors only VCC); 1.2V fixed threshold; push-pull RST; 200ms timeout; AEC-Q100 Grade 1 | Lacks dual-rail monitoring; requires separate ICs for multi-rail systems; higher quiescent current (2.5µA vs 15µA) | Use only when supervising one critical rail; not suitable as drop-in replacement due to missing VCC2 input and different pinout |
Compared with MAX6715AUKTVD3+T, the MAX6717AUKVHD3+T provides higher VCC1/VCC2 thresholds ideal for 5V/3.3V systems, while TPS3808G12QDBVRQ1 offers automotive qualification but lacks dual-supply capability - making MAX6717AUKVHD3+T the optimal choice for space-constrained dual-rail embedded designs requiring precision threshold matching.

FAQ
What is the exact reset threshold voltage for VCC1 and VCC2 on the MAX6717AUKVHD3+T?
The MAX6717AUKVHD3+T has a factory-trimmed VCC1 reset threshold of 4.625V ±125mV and a VCC2 reset threshold of 3.075V ±75mV. These values are specified in the Electrical Characteristics table of the official Maxim datasheet and confirmed by suffix code 'VH' in the part number, which maps to those precise thresholds across the full -40°C to +125°C operating range.
Does the MAX6717AUKVHD3+T support manual reset functionality, and how is it implemented?
Yes, the MAX6717AUKVHD3+T includes an active-low manual-reset input (MR) on pin 3, with an internal 50kΩ pullup resistor to VCC1. Pulling MR low for ≥1µs forces an immediate reset assertion, which remains active for the full 140ms timeout period after MR returns high. This enables direct connection to a momentary switch without external components or debounce circuitry.
What is the reset output configuration of the MAX6717AUKVHD3+T, and what external components are required?
The MAX6717AUKVHD3+T features an active-low open-drain RST output on pin 1. An external pullup resistor (typically 10kΩ to 100kΩ) is required to the appropriate logic rail (e.g., VCC1 or host processor I/O voltage). This configuration allows level-shifting, wired-OR reset busing, and compatibility with bidirectional µP reset pins without contention.
Can the MAX6717AUKVHD3+T operate reliably during deep supply brownouts?
Yes, the MAX6717AUKVHD3+T guarantees correct reset output logic state down to VCC1 or VCC2 = 0.8V - significantly below typical microprocessor supply minimums. This ensures deterministic reset assertion and deassertion even during severe brownout conditions, eliminating the need for supplemental undervoltage lockout circuitry in critical applications.
What package type and footprint does the MAX6717AUKVHD3+T use, and is it RoHS compliant?
The MAX6717AUKVHD3+T uses a 6-pin SOT23-6 package (outline 21-0058, land pattern 90-0175), measuring 1.6mm × 2.9mm with 1.1mm height. The '+' suffix in the package code confirms RoHS compliance and lead-free finish. Its compact size supports high-density PCB layouts in space-constrained portable and industrial designs.
