Product details
Overview
MAX6717UKVDD3+ from Maxim Integrated is a dual-voltage microprocessor supervisory IC in 5-pin SOT23 package, monitoring VCC1 (1.8V–5.0V) and VCC2 (0.9V–3.3V) with factory-trimmed reset thresholds, 210ms minimum reset timeout, and open-drain active-low RST output. It guarantees valid reset assertion down to VCC1 or VCC2 = 0.8V and draws only 14µA typical supply current at 3.6V - used in portable battery-operated equipment for reliable power-up sequencing and brownout protection.
For engineers reviewing the MAX6717UKVDD3+ datasheet, MAX6717UKVDD3+ pinout, MAX6717UKVDD3+ application, or MAX6717UKVDD3+ equivalent, key selection criteria include dual-supply threshold accuracy (±1.5% over temperature), immunity to short VCC transients, manual reset input with 50kΩ internal pullup, and guaranteed operation across –40°C to +85°C industrial temperature range.
Technical Context
The MAX6717UKVDD3+ implements two independent voltage comparators with precision internal references to monitor primary (VCC1) and secondary (VCC2) rails, asserting reset when either falls below its trimmed threshold. Its reset timeout timer starts only after both supplies recover above threshold, ensuring stable deassertion.
It features an active-low manual reset input (MR) with 1µs minimum pulse width and 200ns MR-to-reset delay, and supports system-level reliability via glitch-immune detection (immune to transients <20µs at 100mV overdrive). No watchdog, power-fail, or RSTIN inputs are included - confirmed by Selector Guide and Pin Configuration tables.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC1 Threshold | 4.625V (typ), factory-trimmed - sets precise brownout detection point for main system rail |
| VCC2 Threshold | 3.075V (typ), factory-trimmed - enables accurate monitoring of I/O or auxiliary supply |
| Reset Timeout | 210ms (min) - ensures µP completes full initialization before release |
| Supply Current | 14µA (typ) at 3.6V - minimizes quiescent drain in battery-critical applications |
| Operating Temp | –40°C to +85°C - qualified for industrial and telecom environments |
| Reset Valid Down To | VCC1 or VCC2 ≥ 0.8V - maintains functional reset logic during deep brownout |
| Output Type | Open-drain active-low RST - allows wired-OR configuration and level translation |
Pinout & Package
MAX6717UKVDD3+ uses a 5-pin SOT23-5 package (2.8mm × 2.9mm × 1.3mm), surface-mount, lead-free (+ suffix), with thermal pad not electrically connected.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | RST | Active-low open-drain reset output - requires external pullup; asserts when VCC1 or VCC2 drops below threshold |
| 2 | GND | Analog/digital ground reference - must be low-impedance connection to system ground plane |
| 3 | MR | Active-low manual reset input - internally pulled up to VCC1 (50kΩ); initiates reset on logic-low pulse ≥1µs |
| 4 | VCC2 | Secondary supply input - powers internal circuitry when > VCC1 and sets VCC2 threshold reference |
| 5 | VCC1 | Primary supply input - powers device when > VCC2 and defines main reset threshold reference |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent voltage monitoring | Simultaneous VCC1 (1.8–5.0V) and VCC2 (0.9–3.3V) supervision with separate thresholds - eliminates need for two discrete supervisors |
| Factory-trimmed reset thresholds | VTH1 = 4.625V, VTH2 = 3.075V (typ) with ±1.5% max variation over temperature - removes external resistor calibration |
| Guaranteed reset validity at low VCC | Functional reset assertion guaranteed down to VCC1 or VCC2 = 0.8V - supports ultra-low-power wake-up sequences |
| Low-glitch sensitivity | Immune to VCC transients ≤20µs duration at 100mV overdrive - prevents spurious resets in noisy power environments |
| Ultra-low quiescent current | 14µA typical at 3.6V - extends battery life in always-on portable systems without compromising supervision integrity |
Applications
| Battery-Powered IoT Sensor Node | Industrial PLC I/O Module |
|---|---|
Use Scenario: A wireless sensor node powered by a single Li-ion cell (3.0–4.2V) with 3.3V LDO supplying MCU and 1.8V regulator for RF transceiver. IC Role / Device Role / Timing Role: Dual-supply supervisor ensures MCU remains held in reset until both 3.3V and 1.8V rails stabilize post-power-up and during brownout events. Use Value: Prevents firmware corruption by enforcing 210ms minimum reset hold time while consuming only 14µA - enabling multi-year battery life. | Use Scenario: Modular PLC base unit with isolated 24V DC input converted to 5V and 3.3V rails powering controller and field I/O drivers. IC Role / Device Role / Timing Role: Monitors 5V primary rail and 3.3V logic rail; asserts reset if either sags below 4.625V or 3.075V during load transients or ESD events. Use Value: Guarantees reset validity down to 0.8V on either rail - maintains fail-safe behavior even during severe undervoltage conditions. |
| Network Router Power Management | Medical Point-of-Care Monitor |
Use Scenario: Multi-rail AC/DC-powered router with 12V, 5V, and 3.3V outputs feeding CPU, PHY, and memory subsystems. IC Role / Device Role / Timing Role: Supervises critical 5V and 3.3V domains using dedicated VCC1/VCC2 inputs; manual reset (MR) enables field-service recovery. Use Value: Internal 50kΩ MR pullup eliminates external components; 1µs MR pulse width supports compact pushbutton designs. | Use Scenario: Portable diagnostic monitor with dual-battery backup, requiring deterministic boot sequencing across main and backup 3.3V supplies. IC Role / Device Role / Timing Role: Ensures coordinated reset release only after both supplies exceed 4.625V and 3.075V thresholds - preventing partial initialization faults. Use Value: Factory-trimmed thresholds eliminate calibration drift over 10-year product lifetime - meeting IEC 60601-1 reliability requirements. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-voltage supervisory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6715UTLTD3+ | Same 5-pin SOT23 package, identical VCC1/VCC2 thresholds (4.625V/3.075V) and 210ms timeout, but lacks MR input | No manual reset capability - unsuitable where field-service or test-mode reset is required | Select MAX6717UKVDD3+ when MR functionality is needed; choose MAX6715UTLTD3+ only for cost-sensitive, MR-free designs |
| TPS3808G33DBVR | Single-supply supervisor (monitors only one rail), 3.3V fixed threshold, 200ms timeout, push-pull RST output | Cannot monitor dual rails simultaneously - requires two devices for equivalent coverage | Use only if system has only one critical rail or if board space allows dual TPS3808G33DBVR placement |
Compared with MAX6715UTLTD3+, MAX6717UKVDD3+ adds essential MR functionality without increasing footprint or cost; versus TPS3808G33DBVR, it delivers true dual-rail supervision in half the component count and PCB area - critical for space-constrained medical and portable designs.

FAQ
What is the exact reset threshold voltage for VCC1 and VCC2 on the MAX6717UKVDD3+?
The MAX6717UKVDD3+ has factory-trimmed reset thresholds of 4.625V (typ) for VCC1 and 3.075V (typ) for VCC2, with ±1.5% maximum variation over –40°C to +85°C. These values are encoded in the "VD" suffix per Maxim's Reset Voltage Threshold Suffix Guide and are confirmed in the Electrical Characteristics table. The MAX6717UKVDD3+ does not support adjustable thresholds - all monitoring is fixed and precision-trimmed.
Does the MAX6717UKVDD3+ include a watchdog timer or power-fail functionality?
No, the MAX6717UKVDD3+ does not include watchdog timer (WDI), power-fail input/output (PFI/PFO), or adjustable RSTIN functionality. Per the Selector Guide and Pin Configuration tables, it is a dual-supply supervisor with only VCC1, VCC2, MR, RST, and GND pins. Watchdog and PFI features appear only in higher-numbered variants like MAX6721–MAX6729. The MAX6717UKVDD3+ is purpose-built for simple, low-cost dual-rail monitoring.
What is the reset timeout period of the MAX6717UKVDD3+, and how is it set?
The MAX6717UKVDD3+ has a minimum reset timeout period of 210ms, indicated by the "D3" suffix in its part number per Maxim's Reset Timeout Period Suffix Guide. This value is factory-programmed and non-adjustable. The timeout begins only after both VCC1 and VCC2 rise above their respective thresholds and continues for the full 210ms - ensuring robust µP initialization before reset deassertion.
Can the MAX6717UKVDD3+ operate with supply voltages below 1.0V?
Yes - the MAX6717UKVDD3+ guarantees valid reset output logic state down to VCC1 or VCC2 = 0.8V, as explicitly stated in the General Description and Absolute Maximum Ratings. However, full functionality (e.g., MR input recognition, accurate threshold comparison) requires VCC1 ≥ 0.8V and VCC2 ≥ 0.8V. Below 0.8V, reset behavior is not specified, and the device may enter undefined states.
Is the MAX6717UKVDD3+ pin-compatible with other devices in the MAX6715–MAX6729 family?
The MAX6717UKVDD3+ uses the 5-pin SOT23-5 package and shares pinout compatibility only with other 5-pin variants: MAX6715, MAX6716, MAX6717, MAX6718, MAX6719, and MAX6720. It is not pin-compatible with 6-pin (e.g., MAX6721) or 8-pin (e.g., MAX6725) members. Pin 1 is RST, Pin 2 is GND, Pin 3 is MR, Pin 4 is VCC2, and Pin 5 is VCC1 - consistent across all 5-pin family members.
