Product details
Overview
MAX6717AUKTGD3+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, and guaranteed reset validity down to VCC1 or VCC2 = 0.8V. It supports telecom/networking equipment requiring robust power-rail monitoring during brownout conditions.
For engineers reviewing the MAX6717AUKTGD3+T datasheet, MAX6717AUKTGD3+T pinout, MAX6717AUKTGD3+T application, or MAX6717AUKTGD3+T equivalent, key selection criteria include dual-supply threshold accuracy (±1.5% over temperature), low 14µA typical supply current at 3.6V, immunity to sub-20µs VCC transients, and compatibility with manual-reset and watchdog-free system architectures.
Technical Context
The MAX6717AUKTGD3+T implements independent voltage comparators for VCC1 and VCC2, each referenced to a precision internal bandgap, with hysteresis of 0.5% of threshold voltage to prevent chatter near trip points. Its reset logic asserts active-low RST on any supply drop below threshold and holds for a fixed 280ms timeout after all supplies recover.
This variant lacks RSTIN, WDI, PFI, and PFO pins - confirmed by its pin mapping (VCC1, VCC2, GND, MR, RST, RST2) - and uses open-drain outputs referenced to VCC1 (RST) and VCC2 (RST2), requiring external pullups. It includes an internal 50kΩ MR pullup and guarantees valid reset assertion even when VCC1 or VCC2 drops to 0.8V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC1 Reset Threshold | 4.625V (typ), ±1.5% over -40°C to +125°C - ensures reliable reset assertion for 5V/3.3V primary rails under thermal stress |
| VCC2 Reset Threshold | 3.075V (typ), ±1.5% over -40°C to +125°C - matches common secondary 3.3V or 2.5V supply rails with tight tolerance |
| Reset Timeout Period | 280ms (min), D5 suffix - provides sufficient hold time for slow-start DC-DC converters and firmware initialization |
| Supply Current | 14µA (typ) at 3.6V - enables battery-backed systems to maintain supervision >10 years on coin cell |
| Operating Temperature | -40°C to +125°C - qualified for under-hood automotive and industrial control environments |
| Reset Output Type | Open-drain RST (VCC1-referenced) and RST2 (VCC2-referenced) - allows level-shifting and wired-OR reset bus implementation |
| MR Input Logic | Active-low with 50kΩ internal pullup to VCC1 - eliminates external biasing; 1µs minimum pulse width supports tactile switch debouncing |
Pinout & Package
MAX6717AUKTGD3+T is housed in a 6-pin SOT23-6 package (package code U6+1), with 1.6mm × 2.9mm footprint, 0.95mm height, and thermal resistance θJA = 115°C/W on multilayer board.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | RST / RST1 | Active-low open-drain reset output referenced to VCC1; requires external pullup; asserts when VCC1 or VCC2 falls below threshold or MR is pulled low |
| 2 | GND | Analog/digital ground reference for all internal comparators and timing circuits |
| 3 | MR | Active-low manual-reset input with internal 50kΩ pullup to VCC1; reset remains active for full 280ms timeout after MR release |
| 4 | VCC2 | Secondary supply input (0.8V–5.5V); powers internal VCC2 comparator and drives RST2 output |
| 5 | VCC1 | Primary supply input (0.8V–5.5V); powers core logic, drives RST output, and supplies MR pullup |
| 6 | RST2 | Active-low open-drain reset output referenced to VCC2; independent assertion path for secondary rail monitoring |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent supply monitoring | Simultaneous VCC1 and VCC2 supervision with separate thresholds and hysteresis prevents false resets during asymmetric rail sequencing |
| Guaranteed reset validity to 0.8V | Ensures deterministic reset behavior during deep brownouts where VCC drops below 1.0V - critical for fail-safe shutdown in industrial PLCs |
| Low 14µA supply current | Reduces standby power in always-on systems; enables use in energy-harvesting nodes without compromising supervision duration |
| 280ms fixed reset timeout | Matches typical boot-time requirements of ARM Cortex-M4/M7 MCUs and FPGA configuration cycles without external RC timing components |
| Open-drain dual reset outputs | Allows wired-OR connection of multiple supervisors onto single reset bus and supports mixed-voltage system-level reset coordination |
Applications
| Telecom Line Cards | Industrial PLC Controllers |
|---|---|

IC Role / Device Role / Timing Role: Fault-detection engine triggering hard reset on undervoltage events while maintaining reset assertion through transient noise bursts. Use Value: Eliminates need for external RC timers and reduces BOM count by integrating dual-threshold detection in 1.6mm × 2.9mm footprint. |
| Medical Imaging Power Modules | Automotive ADAS Camera ECUs |
Use Scenario: Validating stable 1.8V sensor interface rail and 3.3V image processor rail in portable ultrasound units powered by Li-ion batteries nearing end-of-discharge. IC Role / Device Role / Timing Role: Brownout detector holding reset until both rails exceed 4.625V and 3.075V thresholds with 280ms debounce, preventing partial boot corruption. Use Value: Enables safe shutdown before ADC reference collapse, preserving diagnostic integrity during battery depletion. |
Use Scenario: Monitoring 5V camera module rail (VCC1) and 1.2V ISP core rail (VCC2) in rear-view camera modules operating at -40°C ambient. IC Role / Device Role / Timing Role: Cold-temperature-stable supervisor asserting reset if either rail sags below spec during cold cranking, with operation guaranteed to -40°C. Use Value: Meets AEC-Q100 Class 0 requirements via design qualification (though this variant is not AEC-Q100 certified, its -40°C to +125°C rating supports automotive thermal profiles). |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-supply supervisory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6715AUKTGD3+T | Identical pinout and package; VCC1 threshold = 4.375V (M suffix), VCC2 = 2.925V (S suffix); same 280ms timeout | Better suited for systems with tighter 4.4V primary rail tolerance; lower VCC2 threshold accommodates 2.8V LDOs | Select when primary supply nominal is 4.5V ±5% rather than 5.0V ±5% |
| TLV809E33DBVR | SOT-23-5, single-supply only (monitors VCC only), 3.08V threshold, 200ms timeout, no MR input, push-pull RST | Lacks VCC2 monitoring and manual reset; simpler architecture for cost-sensitive single-rail applications | Choose only if secondary rail supervision is unnecessary and PCB space is constrained to 5-pin footprint |
Compared with MAX6717AUKTGD3+T, MAX6715AUKTGD3+T offers lower reset thresholds for margin-critical 4.5V systems, while TLV809E33DBVR reduces cost and size at the expense of dual-rail capability and reset flexibility - making MAX6717AUKTGD3+T optimal for multivoltage reliability-critical designs.

FAQ
What is the exact reset threshold voltage for VCC1 and VCC2 on the MAX6717AUKTGD3+T?
The MAX6717AUKTGD3+T has a VCC1 reset threshold of 4.625V (typical, ±1.5% over temperature) and a VCC2 reset threshold of 3.075V (typical, ±1.5% over temperature), per the 'T' and 'S' suffix codes in the Reset Voltage Threshold Suffix Guide. These values are factory-trimmed and do not require external resistor networks.
Does the MAX6717AUKTGD3+T support manual reset functionality?
Yes, the MAX6717AUKTGD3+T includes an active-low manual-reset input (MR) with an internal 50kΩ pullup to VCC1. Pulling MR low forces reset assertion, and the reset remains active for the full 280ms timeout period after MR returns high - enabling hardware-initiated recovery without software intervention.
What package type and pin count does the MAX6717AUKTGD3+T use?
The MAX6717AUKTGD3+T is supplied in a 6-pin SOT23-6 package (outline 21-0058, land pattern 90-0175), with dimensions 1.6mm × 2.9mm × 0.95mm. Pin assignments are VCC1 (pin 5), VCC2 (pin 4), GND (pin 2), MR (pin 3), RST (pin 1), and RST2 (pin 6).
Can the MAX6717AUKTGD3+T monitor three voltage rails?
No, the MAX6717AUKTGD3+T monitors only two rails: VCC1 and VCC2. It does not include RSTIN, PFI, or WDI pins - confirmed by its pin description table and functional diagram. For triple-rail monitoring, consider MAX6719A or MAX6723A variants with RSTIN input.
What is the reset timeout period for the MAX6717AUKTGD3+T and how is it set?
The MAX6717AUKTGD3+T has a fixed 280ms minimum reset timeout period, indicated by the 'D5' suffix in the part number. This value is internally programmed and requires no external components - simplifying layout and eliminating timing drift due to capacitor aging or temperature variation.
