Product details
Overview
The MAX6717UKWGD3+ from Maxim Integrated is a dual-voltage microprocessor supervisory circuit in a 5-pin SOT23 package, monitoring VCC1 (1.62V threshold) and VCC2 (0.788V threshold) with 210ms reset timeout, open-drain active-low RST output, manual reset input, and guaranteed reset validity down to VCC = 0.8V - used for reliable power-up sequencing and brownout protection in battery-powered embedded systems.
For engineers reviewing the MAX6717UKWGD3+ datasheet, MAX6717UKWGD3+ pinout, MAX6717UKWGD3+ application, or MAX6717UKWGD3+ equivalent, key selection criteria include dual-supply threshold accuracy (±2.5% over temperature), ultra-low 14µA supply current at 3.6V, immunity to sub-20µs VCC transients, and compatibility with 1.8V/0.9V core-I/O rail architectures.
Technical Context
This device implements two independent voltage comparators with factory-trimmed thresholds referenced to internal bandgap references, each feeding a shared reset timeout timer. The RST output remains asserted low for ≥210ms after both VCC1 and VCC2 exceed their respective thresholds, with no watchdog or power-fail functionality enabled.
It uses BiCMOS process technology (1072 transistors), features an internal 50kΩ pullup on MR, guarantees correct reset logic state when either VCC1 or VCC2 ≥ 0.8V, and supports operation across –40°C to +85°C with <20ppm/°C reset threshold tempco.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC1 Threshold | 1.62V (typ), ±2.5% tolerance over temperature - sets reliable reset point for 1.8V primary supply |
| VCC2 Threshold | 0.788V (typ), ±2.5% tolerance - enables monitoring of 0.9V secondary rails like core voltages |
| Reset Timeout | 210ms (min) - ensures µP completes full boot before release from reset |
| Supply Current | 14µA (typ) at 3.6V - minimizes quiescent drain in always-on battery systems |
| Operating Temp | –40°C to +85°C - qualified for industrial and extended-temperature embedded use |
| Package | 5-pin SOT23 - 2.9mm × 1.6mm footprint, compatible with high-density PCB layouts |
| Reset Output | Open-drain active-low RST - allows wired-OR with other reset sources and flexible voltage-level translation |
Pinout & Package
MAX6717UKWGD3+ is housed in a 5-pin SOT23 package (2.9mm × 1.6mm × 1.1mm height) with gull-wing leads, RoHS-compliant lead-free finish (+ suffix), and thermal pad not present.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | RST | Active-low open-drain reset output - requires external pullup; asserts when VCC1 < 1.62V or VCC2 < 0.788V |
| 2 | GND | Analog/digital ground reference - must be connected directly to system ground plane |
| 3 | MR | Active-low manual reset input - internally pulled up to VCC1 (50kΩ); initiates reset when pulled low ≥1µs |
| 4 | VCC2 | Secondary supply input - powers internal comparator for VCC2 monitoring and sets RST2 reference if present (not used in this variant) |
| 5 | VCC1 | Primary supply input - powers device core and sets RST output reference; valid down to 0.8V |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent voltage monitoring | Simultaneous supervision of 1.8V I/O (VCC1) and 0.9V core (VCC2) rails without external components |
| Factory-trimmed precision thresholds | 1.62V (VCC1) and 0.788V (VCC2) with ±2.5% max deviation over –40°C to +85°C |
| Guaranteed reset validity at low VCC | Outputs remain functional and correctly asserted even when VCC1 or VCC2 drops to 0.8V |
| Immunity to short VCC transients | No false reset triggered by negative-going glitches ≤20µs (at 100mV overdrive) |
| Ultra-low quiescent current | 14µA typical at 3.6V - extends battery life in portable equipment requiring continuous supervision |
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) supplies 1.8V I/O and 0.9V MCU core via DC/DC converters. IC Role / Device Role / Timing Role: MAX6717UKWGD3+ monitors both converter outputs and holds MCU in reset until both rails stabilize post-power-up or during brownout. Use Value: Prevents firmware corruption by ensuring 210ms minimum reset hold time and rejecting sub-20µs supply noise common in switching regulator environments. | Use Scenario: An industrial programmable logic controller with isolated 24V input stage powering local 5V and 3.3V rails, feeding 1.8V FPGA configuration and 0.9V logic. IC Role / Device Role / Timing Role: Supervises dual downstream regulators to guarantee deterministic FPGA startup and prevent metastability in digital I/O interfaces. Use Value: Factory-trimmed thresholds eliminate need for external resistor dividers, reducing BOM count and layout area in space-constrained DIN-rail modules. |
| Medical Wearable Monitor | Point-of-Sale Terminal |
Use Scenario: A wearable ECG monitor using coin-cell battery (1.8–2.2V) with buck-boost to generate stable 1.8V and 0.9V rails for analog front-end and ARM Cortex-M0+ MCU. IC Role / Device Role / Timing Role: Provides fail-safe reset assertion during battery sag below 2.0V, while maintaining valid reset logic state down to 0.8V VCC1 to avoid premature release. Use Value: 14µA supply current extends operational runtime between battery replacements without compromising supervision reliability. | Use Scenario: A retail POS terminal with hot-swap 12V input, generating 5V USB, 3.3V logic, and 1.8V/0.9V SoC rails - subject to transient surges during peripheral insertion. IC Role / Device Role / Timing Role: Monitors critical 1.8V SoC I/O and 0.9V core supplies; asserts reset only on sustained undervoltage, ignoring brief transients from USB hot-plug events. Use Value: Immunity to ≤20µs VCC glitches prevents spurious reboots during routine peripheral operations, improving system uptime. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-voltage supervisory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6316LUK31D3+ | Single-supply supervisor (VCC only), 3.08V threshold, same 5-pin SOT23 package and 210ms timeout | Lacks VCC2 monitoring - suitable only where secondary rail supervision is unnecessary | Select when only primary rail supervision is required and board space is constrained |
| TPS3808G33DBVR | Single-supply, 3.3V threshold, push-pull RST output, 200ms timeout, 1.5µA IQ | No dual-monitoring capability; lower IQ but incompatible pinout and no MR input hysteresis spec | Prefer for ultra-low-power single-rail systems where manual reset is handled externally |
Compared with MAX6717UKWGD3+, MAX6316LUK31D3+ reduces cost and complexity in single-rail designs, while TPS3808G33DBVR offers lower quiescent current but sacrifices dual-supply visibility and MR integration - making MAX6717UKWGD3+ optimal for compact, battery-operated dual-rail systems requiring guaranteed reset behavior down to 0.8V.

FAQ
What is the exact reset threshold voltage for VCC1 on the MAX6717UKWGD3+?
The MAX6717UKWGD3+ has a factory-trimmed VCC1 reset threshold of 1.62V (typical), with guaranteed limits of 1.575V (min) and 1.665V (max) over –40°C to +85°C. This value is encoded in the "W" suffix per Maxim's Reset Voltage Threshold Suffix Guide and applies specifically to the MAX6717UKWGD3+ variant - not inferred from family data.
Does the MAX6717UKWGD3+ support monitoring a third voltage rail?
No, the MAX6717UKWGD3+ is a dual-voltage supervisor and does not include RSTIN or PFI inputs. Its pinout (5-pin SOT23) and Selector Guide entry confirm it monitors only VCC1 and VCC2. For triple-voltage supervision, consider MAX6719UKWGD3+ or MAX6723UKWGD3+, which add RSTIN functionality.
What is the function of Pin 3 (MR) on the MAX6717UKWGD3+?
Pin 3 is the active-low Manual Reset input (MR) on the MAX6717UKWGD3+. It features an internal 50kΩ pullup to VCC1 and asserts the RST output when pulled low for ≥1µs. Reset remains active for the full 210ms timeout period after MR returns high, enabling hardware-initiated recovery without µP intervention.
Is the reset output of the MAX6717UKWGD3+ push-pull or open-drain?
The MAX6717UKWGD3+ provides an open-drain active-low RST output (Pin 1), as confirmed by its Selector Guide entry and Pin Description table. This requires an external pullup resistor and allows wired-OR connection with other reset sources - unlike push-pull variants such as MAX6718UKWGD3+.
What is the minimum supply voltage at which MAX6717UKWGD3+ guarantees correct reset output logic?
The MAX6717UKWGD3+ guarantees correct reset output logic state when either VCC1 or VCC2 remains ≥0.8V, as explicitly stated in the Absolute Maximum Ratings and Detailed Description sections. Below 0.8V, reset behavior is not specified - a design constraint critical for brownout detection in Li-ion battery systems.
