Product details
Overview
MAX6717UKSVD3 from Maxim Integrated is a dual-voltage microprocessor supervisory circuit in 5-pin SOT23 package, monitoring VCC1 (primary supply) and VCC2 (secondary supply) with factory-trimmed reset thresholds of 4.625V and 3.075V respectively, 210ms minimum reset timeout, and guaranteed reset validity down to VCC1 or VCC2 = 0.8V - used in multivoltage embedded systems requiring reliable power-on reset and brownout detection.
For engineers reviewing the MAX6717UKSVD3 datasheet, MAX6717UKSVD3 pinout, MAX6717UKSVD3 application, or MAX6717UKSVD3 equivalent, this page delivers verified electrical specs, exact SOT23-5 terminal mapping, dual-supply monitoring behavior, manual reset integration, and validated alternative options for telecom, industrial, and portable equipment designs.
Technical Context
The MAX6717UKSVD3 implements two independent voltage comparators with internal reference trimming, asserting an active-low open-drain RST output when either VCC1 falls below 4.625V (±1.5%) or VCC2 drops below 3.075V (±1.5%), with hysteresis of 0.5% and tempco of 20ppm/°C. Reset remains asserted for ≥210ms after both supplies recover above threshold.
It features a manual reset input (MR) with 50kΩ internal pullup to VCC1, glitch rejection of 100ns, and MR-to-reset delay of 200ns; no watchdog, power-fail, or RSTIN functionality - confirmed by Selector Guide and Pin Configuration tables for MAX6717 variant.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC1 Threshold | 4.625V (min 4.500V, max 4.750V) - sets primary supply brownout detection point for 5V or 4.8V rails |
| VCC2 Threshold | 3.075V (min 3.000V, max 3.150V) - enables reliable monitoring of 3.3V I/O or auxiliary supplies |
| Reset Timeout | 210ms (min) - ensures sufficient hold time for processor initialization and peripheral stabilization |
| Supply Current | 14µA typical at 3.6V - supports ultra-low-power battery-operated applications without compromising supervision integrity |
| Operating Temp | -40°C to +85°C - qualified for industrial and extended-temperature embedded deployments |
| Reset Output | Active-low, open-drain - requires external pullup; compatible with bidirectional µP reset pins and mixed-voltage logic interfaces |
| Valid Reset Down To | VCC1 or VCC2 ≥ 0.8V - guarantees correct reset assertion during deep brownout or partial power loss |
Pinout & Package
MAX6717UKSVD3 is housed in a 5-pin SOT23-5 package (2.9mm × 1.6mm × 1.1mm), surface-mount, RoHS-compliant, with gull-wing leads and thermal pad not present. Pin 1 marked by beveled corner or dot.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | RST | Active-low open-drain reset output; sinks current when asserted; requires external pullup to VCC1 or system rail |
| 2 | GND | Ground reference for all internal comparators, timers, and logic; must be low-impedance connection |
| 3 | MR | Active-low manual reset input; internally pulled up to VCC1 (50kΩ); asserts reset when pulled ≤0.3×VCC1 |
| 4 | VCC2 | Secondary supply input; powers internal circuitry when > VCC1; monitored against 3.075V threshold |
| 5 | VCC1 | Primary supply input; powers device when > VCC2; monitored against 4.625V threshold; reference for MR pullup and RST pullup |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent voltage monitoring | Simultaneous supervision of primary (VCC1) and secondary (VCC2) rails eliminates need for discrete comparators or dual ICs |
| Factory-trimmed precision thresholds | 4.625V ±1.5% and 3.075V ±1.5% reduce BOM count and eliminate external resistor calibration |
| Guaranteed reset validity to 0.8V | Ensures deterministic reset behavior during severe undervoltage events where many supervisors fail silently |
| Low 14µA supply current | Minimizes quiescent drain on battery-backed or energy-harvested systems without sacrificing supervision reliability |
| Open-drain RST with manual reset | Enables flexible interface to µPs with bidirectional reset pins and supports wired-OR reset bus architectures |
Applications
| Industrial PLC Power Sequencing | Portable Medical Device Boot Supervision |
|---|---|
Use Scenario: Monitoring 5V main rail and 3.3V I/O rail during cold start and brownout recovery in programmable logic controllers. IC Role / Device Role / Timing Role: Dual-supply supervisor enforcing synchronized reset assertion until both rails stabilize above 4.625V and 3.075V for ≥210ms. Use Value: Prevents firmware lockup or register corruption caused by partial power-up of CPU and peripherals. |
Use Scenario: Ensuring safe boot sequence in handheld diagnostic instruments powered by single-cell Li-ion (3.0–4.2V) with regulated 3.3V and 1.8V outputs. IC Role / Device Role / Timing Role: Detecting VCC2 (3.3V) drop below 3.075V before critical analog front-end fails, triggering controlled shutdown via µP. Use Value: Extends usable battery life by enabling graceful power-down instead of uncontrolled crash during voltage sag. |
| Telecom Line Card Voltage Integrity | Embedded Network Router Core Initialization |
Use Scenario: Verifying stable 4.8V backplane supply and 3.3V management controller rail in carrier-grade line cards operating at -40°C to +85°C. IC Role / Device Role / Timing Role: Providing temperature-stable reset with 20ppm/°C tempco and 0.5% hysteresis to reject noise-induced false resets. Use Value: Eliminates field failures due to marginal supply noise or thermal drift in high-reliability infrastructure. |
Use Scenario: Coordinating power-up of ARM-based SoC (VCC1 = 5V) and DDR memory regulator (VCC2 = 3.3V) in enterprise routers. IC Role / Device Role / Timing Role: Holding reset active until both domains exceed thresholds and remain stable for full 210ms timeout period. Use Value: Guarantees deterministic boot state across heterogeneous voltage domains, avoiding race conditions. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-voltage supervisory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6316LUK46D3-T | Single-supply monitor (4.63V only), same SOT23-5 package, 200ms timeout, 12µA ICC | Lacks VCC2 monitoring - requires separate IC for secondary rail supervision | Select when only primary rail supervision is needed and board space is constrained |
| TPS3808G33DBVR | Single-supply (3.3V), SOT23-6, 200ms timeout, 16µA ICC, push-pull RST | No dual-rail capability; different pinout; higher drive strength but no MR input hysteresis spec | Choose for cost-sensitive 3.3V-only systems where manual reset is optional and push-pull output preferred |
Compared with MAX6717UKSVD3, MAX6316LUK46D3-T reduces integration by omitting VCC2 monitoring, while TPS3808G33DBVR trades dual-rail capability for lower unit cost and push-pull output - neither offers identical dual-threshold, open-drain, MR-enabled supervision in SOT23-5.

FAQ
What is the exact reset threshold voltage for VCC1 and VCC2 on the MAX6717UKSVD3?
The MAX6717UKSVD3 has factory-trimmed reset thresholds of 4.625V for VCC1 (with min/max of 4.500V/4.750V) and 3.075V for VCC2 (with min/max of 3.000V/3.150V), as defined by the 'S' and 'V' suffixes in its part number per Maxim's Reset Voltage Threshold Suffix Guide.
Does the MAX6717UKSVD3 include a watchdog timer or power-fail functionality?
No, the MAX6717UKSVD3 does not include watchdog timer, power-fail input/output (PFI/PFO), or adjustable RSTIN functionality - confirmed by the Selector Guide, which lists it as a dual-monitor device with manual reset only and no WDI or PFI columns enabled.
What is the reset timeout period for the MAX6717UKSVD3, and is it adjustable?
The MAX6717UKSVD3 has a fixed minimum reset timeout period of 210ms, indicated by the 'D3' suffix in its part number; this value is factory-set and not user-adjustable via external components or configuration pins.
Can the MAX6717UKSVD3 operate with VCC1 and VCC2 supplied from different voltage sources?
Yes, the MAX6717UKSVD3 is explicitly designed to monitor independent VCC1 and VCC2 supplies - VCC1 powers the device and references MR/RST, while VCC2 is a separate monitored rail with its own comparator; both may originate from distinct regulators or power domains.
What package type and pin count does the MAX6717UKSVD3 use, and is it RoHS-compliant?
The MAX6717UKSVD3 uses a 5-pin SOT23-5 package (2.9mm × 1.6mm × 1.1mm) and is available in lead-free packaging - specified in the Ordering Information table, where '-T' denotes leaded and '+T' denotes lead-free variants.
