Product details
Overview
MAX6717AUKYDD3+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, open-drain active-low RST output, and guaranteed reset validity down to VCC1 or VCC2 = 0.8V - used in telecom power sequencing and industrial embedded controllers.
For engineers reviewing the MAX6717AUKYDD3+T datasheet, MAX6717AUKYDD3+T pinout, MAX6717AUKYDD3+T application, or MAX6717AUKYDD3+T equivalent, key selection criteria include dual-rail voltage monitoring capability, 140ms reset timeout period, open-drain RST output logic, manual-reset input support, and operation across –40°C to +125°C for automotive-grade power integrity assurance.
Technical Context
The MAX6717AUKYDD3+T implements independent dual-voltage supervision with separate internal comparators for VCC1 and VCC2, each referenced to precision bandgap-derived thresholds. It asserts reset when either supply falls below its trimmed threshold and holds reset for a fixed 140ms (min) timeout after both supplies recover.
It features an integrated manual-reset input (MR) with 50kΩ internal pullup to VCC1, supports no external watchdog or power-fail functions, and uses open-drain RST output referenced to VCC1 - requiring external pullup. Its architecture guarantees valid reset state at VCC ≥ 0.8V, enabling brownout detection in low-power systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC1 Reset Threshold | 4.625V (typ), factory-trimmed - ensures reliable reset assertion during 5V rail collapse before critical logic fails |
| VCC2 Reset Threshold | 3.075V (typ), factory-trimmed - enables precise monitoring of 3.3V auxiliary rails in multivoltage systems |
| Reset Timeout Period | 140ms (min) - provides sufficient hold time for full μP initialization and peripheral stabilization |
| Supply Current | 14µA (typ) at 3.6V - minimizes quiescent load on battery-backed or energy-constrained supplies |
| Operating Temperature | –40°C to +125°C - qualified for under-hood automotive and industrial control environments |
| Reset Output Type | Open-drain active-low RST - allows wired-OR configuration and level-shifting with external pullup |
| Valid Reset Down To | VCC1 or VCC2 = 0.8V - ensures deterministic reset behavior during deep brownout conditions |
Pinout & Package
Package: 6-pin SOT23 (package code U6+1), surface-mount, 1.6mm × 2.9mm footprint, thermal resistance θJA = 115°C/W (multilayer board).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | RST / RST1 | Active-low open-drain reset output referenced to VCC1; requires external pullup resistor |
| 2 | GND | System ground reference for all internal comparators and logic |
| 3 | MR | Active-low manual-reset input with 50kΩ internal pullup to VCC1; initiates reset on logic-low pulse ≥1µs |
| 4 | VCC2 | Secondary supply input powering VCC2 comparator and related circuitry; monitors 0.9V–3.3V rails |
| 5 | VCC1 | Primary supply input powering core logic and VCC1 comparator; monitors 1.8V–5.0V rails |
| 6 | NC | No connect - internally unconnected; must be left floating or tied to GND per layout best practice |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent voltage monitoring | Simultaneous supervision of primary (VCC1) and secondary (VCC2) rails with separate thresholds and hysteresis |
| Factory-trimmed precision thresholds | VTH1 = 4.625V ±125mV and VTH2 = 3.075V ±75mV - eliminates external resistor networks and calibration |
| Guaranteed reset validity at low VCC | Outputs remain functional and logic-determined even as VCC1 or VCC2 drops to 0.8V |
| Low-quiescent-current design | 14µA typical ICC at 3.6V - extends battery life in portable and always-on monitoring applications |
| Industrial temperature grade | –40°C to +125°C operation - supports deployment in engine control units and base station power modules |

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 dual-supply supervision, identical thresholds and timeout, but in 5-pin SOT23 package with no MR pin | Lacks manual-reset functionality - unsuitable where field service or test-mode reset is required | Select MAX6717AUKYDD3+T when MR input is needed; choose MAX6717AUTTWD3+T only for space-constrained designs without manual reset |
| TPS3808G33DBVR | Single-supply supervisor (monitors only VCC), 3.3V fixed threshold, 200ms timeout, push-pull RST output | Cannot monitor dual rails simultaneously; requires external circuitry for VCC2 supervision | Use only if system has single-rail architecture and push-pull drive is preferred; not a functional substitute for dual-rail monitoring |
Compared with MAX6717AUTTWD3+T, the MAX6717AUKYDD3+T adds MR functionality in a 6-pin package - enabling field-service reset without hardware modification. Against TPS3808G33DBVR, it delivers true dual-rail supervision with factory-trimmed thresholds, eliminating external resistive dividers and reducing design risk in multivoltage systems.

FAQ
What is the exact reset timeout period of the MAX6717AUKYDD3+T?
The MAX6717AUKYDD3+T has a guaranteed minimum reset timeout period of 140ms, with typical value 210ms and maximum 280ms. This fixed delay begins when VCC1 and VCC2 rise above their respective thresholds and ensures sufficient hold time for microprocessor initialization and peripheral configuration before release.
Does the MAX6717AUKYDD3+T support monitoring a third voltage rail?
No, the MAX6717AUKYDD3+T does not support RSTIN or PFI inputs - it is a dual-supply-only variant. Only MAX6719A/MAX6720A and MAX6723A–MAX6727A variants include the adjustable RSTIN input for triple-voltage monitoring. The MAX6717AUKYDD3+T monitors only VCC1 and VCC2.
What is the function of Pin 6 (NC) on the MAX6717AUKYDD3+T?
Pin 6 on the MAX6717AUKYDD3+T is designated NC (No Connect) and is internally unconnected. It must be left floating or tied to GND per PCB layout best practices to avoid parasitic coupling; it does not support any functional input, output, or biasing role in this variant.
Can the MAX6717AUKYDD3+T operate with VCC1 = 1.8V and VCC2 = 1.2V?
Yes, the MAX6717AUKYDD3+T operates with VCC1 as low as 1.8V and VCC2 as low as 0.9V per datasheet specifications. Its 4.625V VTH1 and 3.075V VTH2 thresholds remain valid, and reset output is guaranteed functional down to VCC1 or VCC2 = 0.8V - making it suitable for modern low-voltage SoC power domains.
Is the MAX6717AUKYDD3+T pin-compatible with other MAX6717x variants?
The MAX6717AUKYDD3+T is pin-compatible with other 6-pin SOT23 MAX6717x variants (e.g., MAX6717AUTTWD3+T is 5-pin and not pin-compatible). All 6-pin versions share identical pinout: Pin 1=RST, Pin 2=GND, Pin 3=MR, Pin 4=VCC2, Pin 5=VCC1, Pin 6=NC - enabling drop-in replacement within same package family.
