Product details
Overview
MAX6717AUKZGD3+ from Maxim Integrated is a dual-voltage microprocessor supervisory circuit 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, open-drain active-low RST output, and guaranteed reset validity down to VCC1 or VCC2 = 0.8V - used in portable battery-powered equipment for reliable power-up sequencing and brownout protection.
For engineers reviewing the MAX6717AUKZGD3+ datasheet, MAX6717AUKZGD3+ pinout, MAX6717AUKZGD3+ application, or MAX6717AUKZGD3+ equivalent, key selection criteria include dual-supply threshold accuracy (±1.5% over temperature), ultra-low 14µA typical supply current at 3.6V, immunity to sub-100ns VCC transients, and compatibility with manual-reset and watchdog-free system architectures.
Technical Context
The MAX6717AUKZGD3+ implements independent voltage comparators for VCC1 and VCC2, each with 0.5% hysteresis referenced to its threshold, and asserts reset when either supply falls below its trimmed threshold. It uses internal bandgap reference (626.5mV) for threshold stability and features 20µs typical VCC-to-RST delay with no external components required.
Reset assertion is latched for a fixed 210ms (min) timeout after all monitored supplies recover; the timer restarts if any supply dips again before timeout completion. The device operates across -40°C to +125°C and maintains valid reset logic state even as VCC1 or VCC2 decays to 0.8V - critical for graceful shutdown in low-power embedded systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC1 Threshold | 4.625V (factory-trimmed, ±1.5% over temp) - sets primary supply brownout detection point for 5V rail monitoring |
| VCC2 Threshold | 3.075V (factory-trimmed, ±1.5% over temp) - enables secondary supply monitoring of 3.3V I/O domain |
| Reset Timeout | 210ms (minimum) - ensures µP completes boot sequence before releasing reset |
| Supply Current | 14µA (typ at 3.6V) - minimizes quiescent drain in always-on battery backup circuits |
| Operating Temp | -40°C to +125°C - supports industrial and automotive under-hood applications |
| Reset Output | Open-drain active-low RST - allows wired-OR reset bus sharing and flexible pullup voltage selection |
| VCC Validity | Reset guaranteed valid down to VCC1 or VCC2 = 0.8V - enables deterministic reset release during deep brownout |
Pinout & Package
Package: 5-pin SOT23 (1.6mm × 2.9mm × 1.1mm, 0.95mm pitch), RoHS-compliant, tape-and-reel.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - RST | Active-low reset output | Open-drain driver referenced to VCC1; requires external pullup; asserts low on VCC1/VCC2 undervoltage |
| 2 - GND | Ground reference | Common return for all internal comparators, timers, and output drivers |
| 3 - MR | Active-low manual-reset input | Internal 50kΩ pullup to VCC1; logic-low pulse ≥1µs forces reset assertion |
| 4 - VCC2 | Secondary supply input | Powers internal VCC2 comparator and sets VCC2 reset threshold reference; monitors 0.9V–3.3V rails |
| 5 - VCC1 | Primary supply input | Powers device core and sets VCC1 reset threshold reference; monitors 1.8V–5.0V rails |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent voltage monitoring | Simultaneous VCC1 and VCC2 supervision with separate thresholds eliminates need for two discrete supervisors |
| Factory-trimmed precision thresholds | ±1.5% total accuracy over -40°C to +125°C reduces calibration overhead in production test |
| Ultra-low quiescent current | 14µA typical at 3.6V extends battery life in always-on monitoring circuits (e.g., RTC backup) |
| Glitch-immune reset timing | Immunity to VCC transients <100ns prevents spurious resets during switching noise events |
| Valid reset down to 0.8V supply | Ensures controlled reset deassertion during deep brownout - avoids undefined µP state |
Applications
| Battery-Powered IoT Sensor Node | Industrial PLC I/O Module |
|---|---|
Use Scenario: Monitors Li-ion battery voltage (VCC1) and 3.3V sensor rail (VCC2) during cold-start and deep discharge. IC Role / Device Role / Timing Role: Dual-supply supervisor asserting reset until both rails stabilize above 4.625V and 3.075V respectively, with 210ms hold time. Use Value: Prevents firmware execution on marginal power - eliminates corrupted sensor readings and radio transmission errors. | Use Scenario: Ensures deterministic startup of ARM-based controller and isolated CAN transceiver after 24V DC input fluctuation. IC Role / Device Role / Timing Role: Supervises primary 5V logic supply and secondary 3.3V I/O supply; MR pin tied to front-panel reset button. Use Value: Guarantees µP reset remains asserted until both domains are fully regulated - avoids CAN bus arbitration failure at power-up. |
| Medical Wearable ECG Monitor | Automotive Body Control Module (BCM) |
Use Scenario: Validates 1.8V analog front-end and 3.3V digital core supplies before enabling ADC sampling and Bluetooth LE transmission. IC Role / Device Role / Timing Role: Dual-threshold supervisor with open-drain RST shared across multiple subsystems via pullup to 3.3V. Use Value: Eliminates need for discrete RC reset networks - improves timing repeatability across temperature and unit-to-unit variation. | Use Scenario: Monitors 5V microcontroller supply and 3.3V CAN transceiver supply in under-dash environment with wide thermal cycling. IC Role / Device Role / Timing Role: Industrial-grade supervisor operating from -40°C to +125°C; reset timeout ensures bootloader execution completes before peripheral initialization. Use Value: Meets AEC-Q100 stress requirements without derating - reduces qualification effort for automotive Tier-1 suppliers. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-voltage supervisory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6716AUTLTD3+T | 6-pin SOT23, push-pull RST output, same VCC1/VCC2 thresholds and 210ms timeout | Requires PCB layout change for 6-pin footprint; eliminates need for external pullup resistor | Select when board space allows larger package and system requires active-drive reset signal |
| TPS3808G33DBVR | Single-supply supervisor (3.3V only), 200ms timeout, 1.6µA IQ, SOT23-5 | Monitors only one rail; lacks VCC2 input and dual-threshold capability | Select only for single-rail systems where cost and ultra-low IQ outweigh dual-monitoring need |
Compared with MAX6716AUTLTD3+T, MAX6717AUKZGD3+ saves board area and simplifies BOM with open-drain RST but requires external pullup; versus TPS3808G33DBVR, it provides true dual-rail supervision essential for mixed-voltage SoC designs - not a drop-in replacement.

FAQ
What is the exact reset threshold voltage for VCC1 and VCC2 on the MAX6717AUKZGD3+?
The MAX6717AUKZGD3+ has factory-trimmed VCC1 reset threshold of 4.625V (±1.5% over -40°C to +125°C) and VCC2 threshold of 3.075V (±1.5%). These values are encoded in the part number suffix 'ZG' per Maxim's Reset Voltage Threshold Suffix Guide and are verified in the Electrical Characteristics table of the official datasheet.
Does the MAX6717AUKZGD3+ support watchdog functionality?
No, the MAX6717AUKZGD3+ does not include watchdog functionality. It belongs to the MAX6715A–MAX6718A subgroup, which omits WDI pin and internal watchdog timer. Watchdog capability is present only in MAX6721A–MAX6729A/MAX6797A variants - confirmed by pin configuration tables showing pin 5 as unused (no WDI) for MAX6717A.
Can the MAX6717AUKZGD3+ monitor a third voltage rail?
No, the MAX6717AUKZGD3+ is a dual-supply supervisor only. It monitors VCC1 and VCC2 exclusively. Third-rail monitoring (via RSTIN) is supported only in MAX6719A/MAX6720A and MAX6723A–MAX6727A variants - confirmed by absence of RSTIN pin in the MAX6717A pin description and functional block diagram.
What is the reset output type and drive strength of the MAX6717AUKZGD3+?
The MAX6717AUKZGD3+ features an open-drain, active-low RST output (pin 1). It sinks up to 3.2mA at VCC ≥ 4.5V with VOL ≤ 0.4V, and requires an external pullup resistor. This is specified in the "RESET/POWER-FAIL OUTPUTS" section of the datasheet and confirmed by pin function description stating "open-drain outputs require an external pullup resistor."
Is the MAX6717AUKZGD3+ compatible with 1.8V-only systems?
Yes, the MAX6717AUKZGD3+ supports VCC1 as low as 1.8V and VCC2 as low as 0.9V, with guaranteed reset validity down to 0.8V on either supply. Its 4.625V/3.075V thresholds are appropriate for monitoring higher rails, but the device itself operates correctly in 1.8V systems - validated by Absolute Maximum Ratings (VCC = 0.8V to 5.5V) and Electrical Characteristics test conditions.
