Product details
Overview
MAX6717UKYDD3-T from Maxim Integrated is a dual-voltage microprocessor supervisory circuit in 5-pin SOT23 package, monitoring VCC1 (primary) and VCC2 (secondary) supplies with factory-trimmed reset thresholds of 2.125V (VTH1) and 2.125V (VTH2), 210ms minimum reset timeout, and open-drain active-low RST output. It ensures reliable system reset during brownout conditions in battery-powered embedded controllers.
For engineers reviewing the MAX6717UKYDD3-T datasheet, MAX6717UKYDD3-T pinout, MAX6717UKYDD3-T application, or MAX6717UKYDD3-T equivalent, this device supports dual-supply monitoring down to 0.8V operation, offers manual reset input with internal 50kΩ pullup, and delivers ultra-low 14µA typical supply current at 3.6V - critical for portable equipment power budgeting.
Technical Context
The MAX6717UKYDD3-T integrates two independent voltage comparators with ±1.5% threshold accuracy over -40°C to +85°C, each referenced to a precision bandgap and featuring 0.5% hysteresis. Its reset logic asserts RST low when either VCC1 or VCC2 falls below its respective threshold and holds reset for ≥210ms after both supplies recover.
It includes a dedicated manual reset input (MR) with 1µs minimum pulse width support and 100ns glitch rejection, and guarantees valid reset state even when VCC1 or VCC2 drops to 0.8V - enabling robust operation during deep brownout events without external supervision.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC1 Reset Threshold | 2.125V (typ), ±1.5% tolerance - sets precise brownout detection point for primary supply |
| VCC2 Reset Threshold | 2.125V (typ), ±1.5% tolerance - enables matched dual-rail monitoring for I/O and core domains |
| Reset Timeout Period | 210ms (min) - ensures µP completes full initialization before release from reset |
| Supply Current | 14µA (typ) at 3.6V - minimizes quiescent drain in always-on battery backup paths |
| Operating Temperature | -40°C to +85°C - qualified for industrial and telecom edge equipment environments |
| Reset Output Type | Open-drain active-low RST - allows wired-OR configuration and level-shifting flexibility |
| MR Input Pullup | 50kΩ internal to VCC1 - eliminates need for external resistor in manual reset switch interface |
Pinout & Package
MAX6717UKYDD3-T is housed in a 5-pin SOT23-5 package (2.9mm × 1.6mm × 1.1mm), optimized for space-constrained PCB layouts in portable and industrial systems.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | RST | Active-low open-drain reset output; requires external pullup; asserts when VCC1/VCC2 < threshold |
| 2 | GND | Analog/digital ground reference for all internal comparators and logic |
| 3 | MR | Active-low manual reset input; internally pulled up to VCC1; 1µs pulse width sufficient |
| 4 | VCC2 | Secondary supply input (0.9V–3.3V range); powers comparator for VCC2 monitoring |
| 5 | VCC1 | Primary supply input (1.8V–5.0V range); powers device core and VCC1 comparator |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent voltage monitoring | Simultaneous VCC1 and VCC2 supervision with separate thresholds avoids single-point failure |
| Guaranteed reset validity down to 0.8V | Ensures deterministic reset assertion even during severe brownout - no undefined state |
| Immunity to short VCC transients | Rejects ≤20µs negative glitches (at 100mV overdrive), preventing spurious resets |
| Low supply current (14µA typ) | Extends battery life in always-on monitoring applications such as smart sensors and IoT nodes |
| Integrated MR pullup (50kΩ) | Reduces BOM count and layout area by eliminating external pullup resistor |
Applications
| Industrial PLC Modules | Portable Medical Devices |
|---|---|
Use Scenario: Compact programmable logic controller modules powered by dual-rail DC/DC converters (e.g., 3.3V I/O + 1.8V core). IC Role / Device Role / Timing Role: Dual-supply supervisor ensuring synchronized reset across logic and analog subsystems during input voltage sag. Use Value: Prevents firmware corruption by guaranteeing reset hold time ≥210ms while supporting operation down to 0.8V on either rail. |
Use Scenario: Battery-powered glucose meters and pulse oximeters requiring long shelf life and reliable boot integrity. IC Role / Device Role / Timing Role: Low-quiescent supervisor monitoring main Li-ion supply (VCC1) and backup coin-cell rail (VCC2). Use Value: 14µA typical ICC enables >10-year shelf life; open-drain RST interfaces cleanly with µP's bidirectional reset pin. |
| Telecom Line Cards | Embedded Point-of-Sale Terminals |
Use Scenario: Hot-swappable line cards in carrier-grade switches with redundant 3.3V and 1.2V power domains. IC Role / Device Role / Timing Role: Fault-tolerant reset generator asserting RST only when both rails fail - avoids false triggers during transient load steps. Use Value: ±1.5% threshold accuracy and 0.5% hysteresis ensure stable trip points across temperature and voltage drift. |
Use Scenario: Retail terminals using ARM-based SoCs with separate 5V USB host, 3.3V peripherals, and 1.2V core supplies. IC Role / Device Role / Timing Role: Dual-rail supervisor verifying both 3.3V and 1.2V rails before releasing SoC from reset. Use Value: 210ms timeout aligns with SoC boot ROM execution window; MR pin enables hardware-initiated recovery via front-panel button. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-voltage supervisory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6316MUT4D3-T | Single-supply monitor (VCC only), 2.63V threshold, same 210ms timeout, SOT23-5 | Lacks VCC2 monitoring - suitable only where secondary rail supervision is unnecessary | Select when system uses only one regulated supply and board space is identical |
| TPS3808G125DBVR | Single-supply, 1.25V threshold, 200ms timeout, push-pull RST, higher ICC (22µA) | No dual-rail capability; different threshold and output drive - requires redesign of reset net | Choose for ultra-low-threshold applications where VCC2 monitoring is omitted and push-pull drive is preferred |
Compared with MAX6717UKYDD3-T, the MAX6316MUT4D3-T reduces functionality (single-rail only) but maintains identical footprint and timeout, while the TPS3808G125DBVR trades dual monitoring for lower threshold and higher supply current - neither offers drop-in replacement capability.

FAQ
What is the exact reset threshold voltage for VCC1 and VCC2 on the MAX6717UKYDD3-T?
The MAX6717UKYDD3-T has factory-trimmed reset thresholds of 2.125V (typ) for both VCC1 and VCC2, with ±1.5% tolerance over temperature. This is confirmed by the "Y" suffix in the part number per Maxim's Reset Voltage Threshold Suffix Guide, corresponding to 2.125V nominal for both rails.
Does the MAX6717UKYDD3-T support manual reset, and how is it implemented?
Yes, the MAX6717UKYDD3-T includes an active-low manual reset (MR) input on Pin 3, featuring an internal 50kΩ pullup to VCC1. A momentary low pulse ≥1µs on MR forces RST assertion for the full 210ms timeout period, enabling hardware-initiated recovery without external components.
What is the reset output configuration of the MAX6717UKYDD3-T, and what does it require externally?
The MAX6717UKYDD3-T provides an open-drain active-low RST output on Pin 1. It requires an external pullup resistor to a valid logic rail (e.g., VCC1 or another system voltage) to generate a defined HIGH state when deasserted - no internal pullup is present on the RST pin itself.
Can the MAX6717UKYDD3-T operate reliably if one supply drops below 1.0V?
Yes - the MAX6717UKYDD3-T guarantees valid reset output logic state as long as either VCC1 or VCC2 remains ≥0.8V. This enables deterministic reset behavior during deep brownout conditions where one rail collapses while the other sustains minimal operation.
What is the supply current consumption of the MAX6717UKYDD3-T at 3.6V, and how does it vary with temperature?
The MAX6717UKYDD3-T draws 14µA (typ) at 3.6V and +25°C, rising to ≤39µA maximum across -40°C to +85°C. This ultra-low ICC supports multi-year battery life in always-on monitoring applications without compromising supervision accuracy.
