Product details
Overview
MAX6717AUKSHD3+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), 140ms minimum reset timeout, and open-drain active-low RST output. It ensures reliable system reset during power-up, brownout, or undervoltage events in multivoltage embedded systems.
For engineers reviewing the MAX6717AUKSHD3+T datasheet, MAX6717AUKSHD3+T pinout, MAX6717AUKSHD3+T application, or MAX6717AUKSHD3+T equivalent, key selection criteria include dual-supply monitoring capability, guaranteed reset validity down to VCC = 0.8V, low 14µA typical supply current at 3.6V, and compatibility with manual-reset and watchdog-free configurations.
Technical Context
The MAX6717AUKSHD3+T implements independent voltage comparators for VCC1 and VCC2, each with ±0.5% hysteresis and 20ppm/°C tempco, asserting reset when either supply falls below its threshold. Its internal reset timer guarantees ≥140ms assertion after all supplies recover, with immunity to sub-20µs VCC transients.
This variant lacks RSTIN, WDI, PFI, and PFO pins-confirmed by pin mapping-and supports only primary/secondary supply monitoring with manual-reset (MR) input and open-drain RST output referenced to VCC1. It operates across –40°C to +125°C with no watchdog or power-fail functionality.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | VCC1/VCC2 = 0.8V to 5.5V - enables operation during deep brownout and compatibility with 1.2V–5V logic domains. |
| VCC1 Reset Threshold | 4.625V (typ), ±125mV tolerance - precisely targets 4.63V nominal systems like 4.5V–5V I/O rails. |
| VCC2 Reset Threshold | 3.075V (typ), ±75mV tolerance - matches common 3.3V core supply monitoring with margin for ripple. |
| Reset Timeout Period | 140ms (min), 210ms (typ), 280ms (max) - exceeds typical µP power-on reset requirements and ensures stable initialization. |
| Supply Current | 14µA (typ) at 3.6V - minimizes quiescent load on battery or low-power auxiliary rails. |
| Reset Output Type | Open-drain active-low RST - allows wired-OR configuration and flexible pullup voltage selection (e.g., to 1.8V or 3.3V domain). |
| Operating Temperature | –40°C to +125°C - qualified for under-hood automotive, industrial control, and telecom equipment environments. |
Pinout & Package
MAX6717AUKSHD3+T is housed in a 6-pin SOT23-6 package (package code U6+1), with 1.6mm × 2.9mm footprint and 0.95mm height, optimized for space-constrained PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | RST / RST1 | Active-low open-drain reset output asserted when VCC1 or VCC2 drops below threshold; requires external pullup; referenced to VCC1. |
| 2 | GND | Ground reference for all internal comparators and logic; must be low-impedance connection to system ground plane. |
| 3 | MR | Active-low manual-reset input with internal 50kΩ pullup to VCC1; pulse ≥1µs forces reset; immune to <100ns glitches. |
| 4 | VCC2 | Secondary supply input powering comparator for VCC2 monitoring; also serves as reference for optional RST2 output (not present in this variant). |
| 5 | VCC1 | Primary supply input powering device core and VCC1 comparator; defines RST output voltage domain and MR pullup target. |
| 6 | NC | No connect - pin 6 is unbonded and must remain floating; not used for thermal pad or biasing. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent supply monitoring | Simultaneous VCC1 (4.625V) and VCC2 (3.075V) threshold detection with separate comparators eliminates need for discrete supervisors. |
| Guaranteed reset validity down to 0.8V | Ensures correct RST logic state even during severe brownout-critical for fail-safe shutdown in automotive and industrial systems. |
| Low 14µA supply current | Reduces standby power draw in always-on subsystems such as real-time clocks or sensor hubs powered from coin cells or energy harvesters. |
| Immunity to short VCC transients | Rejects <20µs negative-going glitches-prevents spurious resets during switching noise or ESD events without external filtering. |
| –40°C to +125°C operation | Validated performance across full automotive and extended industrial temperature range without derating or external compensation. |
Applications
| Industrial PLC Controller | Automotive Body Control Module |

Use Scenario: Integrated into Class II medical infusion pump mainboard to supervise 5V motor driver rail and 3.3V safety-critical MCU supply per IEC 62304. IC Role / Device Role / Timing Role: Generates fail-safe reset signal that halts motor actuation if either supply deviates beyond ±3% of nominal, with manual override via clinician button (MR). Use Value: Supports Class B software safety architecture by providing hardware-enforced power validation independent of MCU firmware execution. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-supply supervisory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6715AUKS4+T | Same 6-pin SOT23 package but with 4.5V VCC1 threshold (4.500V typ) and 1.1ms reset timeout - shorter assertion period. | Suitable for fast-boot µPs requiring minimal reset hold time; less margin for slow-rising supplies. | Select when system boot completes in <2ms and tighter VCC1 threshold (4.5V vs. 4.625V) aligns with 4.5V nominal rail. |
| TPS3808G33DBVR | TI part in SOT23-6 with 3.3V fixed VDD threshold, 200ms timeout, and push-pull RST - no VCC2 monitoring capability. | Monitors single supply only; requires external circuitry for dual-rail supervision. | Choose only if design uses single 3.3V supply or adds discrete comparator for second rail; not drop-in compatible. |
Compared with MAX6717AUKSHD3+T, MAX6715AUKS4+T offers faster reset release but reduced voltage margin, while TPS3808G33DBVR sacrifices dual-supply capability for higher drive strength and TI ecosystem integration-neither is pin-compatible nor functionally equivalent without board redesign.

FAQ
What is the exact reset threshold voltage for VCC1 on MAX6717AUKSHD3+T?
The MAX6717AUKSHD3+T has a factory-trimmed VCC1 reset threshold of 4.625V (typical), with a guaranteed range of 4.500V to 4.750V at 25°C. This value is fixed and non-adjustable, matching the 'H' suffix in the ordering code per Maxim's Reset Voltage Threshold Suffix Guide.
Does MAX6717AUKSHD3+T support watchdog timer functionality?
No, MAX6717AUKSHD3+T does not include watchdog timer functionality. Pin 6 is NC, and the device lacks WDI input capability-confirmed by its position in the MAX6717A/MAX6718A subgroup which omits watchdog features per the Selector Guide and Functional Diagram.
What is the reset timeout period for MAX6717AUKSHD3+T, and is it adjustable?
The MAX6717AUKSHD3+T provides a fixed minimum reset timeout period of 140ms (D3 suffix), with typical 210ms and maximum 280ms values across temperature and voltage. This timing is internally set and not adjustable via external components or configuration pins.
Can MAX6717AUKSHD3+T monitor a third supply voltage via RSTIN?
No, MAX6717AUKSHD3+T does not support RSTIN functionality. The RSTIN pin is absent-pin 6 is NC-and the device belongs to the MAX6717A/MAX6718A variant group explicitly defined as dual-supply-only (no auxiliary voltage monitoring) in the Pin Description table.
What package type and footprint does MAX6717AUKSHD3+T use?
MAX6717AUKSHD3+T uses a 6-pin SOT23-6 package (outline 21-0058, land pattern 90-0175), with 0.95mm height, 1.6mm × 2.9mm body, and 0.95mm pitch. It is RoHS-compliant and compatible with standard SOT23 reflow profiles per JEDEC J-STD-020.
