Product details
Overview
MAX6717UKZGD3+T from Maxim Integrated is a dual-voltage microprocessor supervisory circuit in 5-pin SOT23 package, monitoring VCC1 (1.575V threshold) and VCC2 (0.788V threshold) with 210ms minimum 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 MAX6717UKZGD3+T datasheet, MAX6717UKZGD3+T pinout, MAX6717UKZGD3+T application, or MAX6717UKZGD3+T 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
The MAX6717UKZGD3+T integrates two independent voltage comparators with factory-trimmed thresholds (VTH1 = 1.575V, VTH2 = 0.788V), a 210ms reset timeout timer, and logic-controlled reset assertion via VCC1/VCC2 undervoltage detection or MR low pulse. It guarantees correct reset state when either supply remains ≥0.8V, enabling robust operation during deep brownouts.
Its open-drain RST output requires external pullup and drives low on fault; MR features internal 50kΩ pullup to VCC1 and accepts TTL/CMOS logic levels. No watchdog, power-fail, or RSTIN functionality is included - confirmed by Selector Guide and Pin Configuration tables for MAX6717 series.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC1 Threshold | 1.575V (typ), ±2.5% over -40°C to +85°C - sets primary supply brownout detection point for 1.8V I/O rails |
| VCC2 Threshold | 0.788V (typ), ±2.5% over -40°C to +85°C - enables monitoring of 0.9V core supplies with margin |
| Reset Timeout | 210ms (min) - ensures µP reset hold time exceeds typical boot initialization sequences |
| Supply Current | 14µA (typ) at 3.6V - supports multi-year battery life in portable equipment |
| Operating Temp | -40°C to +85°C - qualified for industrial and telecom edge applications |
| Reset Output | Open-drain, active-low RST - compatible with bidirectional µP reset pins and level-shifted interfaces |
| VCC Validity | Reset logic guaranteed valid down to VCC1 or VCC2 = 0.8V - prevents spurious resets during slow power ramps |
Pinout & Package
MAX6717UKZGD3+T is housed in a 5-pin SOT23 package (2.9mm × 1.6mm × 1.1mm), surface-mount, lead-free (+T suffix), RoHS-compliant. Pin 1 marked with dot; pin numbering follows standard SOT23 convention (counterclockwise from mark).
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | RST | Active-low open-drain reset output - must be pulled up externally; asserts low on VCC1/VCC2 fault or MR low |
| 2 | GND | Analog/digital ground reference - common return for all internal comparators and timers |
| 3 | MR | Active-low manual reset input - internal 50kΩ pullup to VCC1; 1µs minimum pulse width required |
| 4 | VCC2 | Secondary supply input - powers internal circuitry when > VCC1 and sets VTH2 comparator reference |
| 5 | VCC1 | Primary supply input - powers device when > VCC2 and sets VTH1 comparator reference |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent voltage monitoring | Simultaneous 1.575V (VCC1) and 0.788V (VCC2) thresholds enable 1.8V/0.9V rail supervision without external resistors |
| Guaranteed reset validity at low VCC | Correct RST logic state maintained even when VCC1 or VCC2 drops to 0.8V - critical for graceful brownout recovery |
| Ultra-low quiescent current | 14µA typical at 3.6V - reduces system standby power by >90% vs. discrete supervisor solutions |
| Immunity to short VCC transients | No reset assertion for negative-going VCC glitches <20µs (at 100mV overdrive) - eliminates false resets in noisy environments |
| Manual reset with integrated pullup | 50kΩ internal MR pullup to VCC1 eliminates external resistor - simplifies PCB layout and reduces BOM count |
Applications
| Industrial PLC I/O Modules | Portable Medical Sensors |
|---|---|
Use Scenario: Compact programmable logic controller modules powered by dual DC-DC outputs (3.3V I/O, 1.2V FPGA core). IC Role / Device Role: Dual-rail supervisor ensuring synchronized reset assertion across I/O and processing domains during input voltage sag. Use Value: Prevents partial initialization and metastability by holding reset until both 3.3V and 1.2V rails stabilize above 1.575V and 0.788V respectively. |
Use Scenario: Battery-powered glucose monitor with 1.8V MCU and 0.9V sensor interface ASIC. IC Role / Device Role: Low-power supervisor monitoring main LDO (1.8V) and sensor bias rail (0.9V) to guarantee safe shutdown before battery depletion. Use Value: 14µA supply current extends single-CR2032 battery life beyond 3 years in sleep mode while maintaining accurate undervoltage detection. |
| Network Edge Routers | Smart Energy Meters |
Use Scenario: Fanless enterprise switch operating in uncontrolled ambient (-20°C to +70°C) with 1.2V CPU and 3.3V PHY supplies. IC Role / Device Role: Temperature-stable dual-supply monitor providing reset hold time exceeding PHY lock-in and CPU PLL stabilization periods. Use Value: ±2.5% threshold accuracy over full temperature range avoids premature resets during cold startup or thermal throttling events. |
Use Scenario: ANSI C12.20-certified electricity meter using isolated 5V auxiliary and 1.8V metrology ADC supplies. IC Role / Device Role: Supervisory guardrail ensuring metrology subsystem resets cleanly if either supply dips below specification during line transients. Use Value: Guaranteed reset validity down to 0.8V prevents latch-up during 100ms AC zero-crossing dropout events on auxiliary rail. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-voltage supervisory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS3808G15DBVR | Fixed 1.5V VDD threshold only; no secondary supply monitor - requires external resistor divider for second rail | Lacks native dual-threshold architecture; adds design complexity and component count for dual-rail systems | Select when only primary rail supervision is needed and board space permits external feedback network |
| ADM6717AKSZ-REEL7 | Same 5-pin SOT23 package, but 1.6V/0.8V thresholds and 200ms timeout - tighter tolerance (±1.5%) but no MR input | Missing manual reset function eliminates field serviceability and test-mode entry capability | Choose for higher-precision single-point monitoring where operator-initiated reset is unnecessary |
Compared with TPS3808G15DBVR and ADM6717AKSZ-REEL7, MAX6717UKZGD3+T uniquely delivers factory-trimmed dual thresholds, integrated MR with pullup, and guaranteed 0.8V VCC operation - making it optimal for compact, battery-sensitive dual-rail systems requiring field serviceability and brownout resilience.

FAQ
What is the exact reset threshold voltage for VCC1 and VCC2 on MAX6717UKZGD3+T?
The MAX6717UKZGD3+T has factory-trimmed reset thresholds of 1.575V (typical, ±2.5%) for VCC1 and 0.788V (typical, ±2.5%) for VCC2, as defined by the 'Z' and 'G' suffixes per Maxim's Reset Voltage Threshold Suffix Guide - verified in Electrical Characteristics Table on page 2 of the datasheet.
Does MAX6717UKZGD3+T include watchdog or power-fail functionality?
No, MAX6717UKZGD3+T does not include watchdog timer or power-fail input/output. Per the Selector Guide and Pin Configuration table, it is a dual-supply-only variant with RST, GND, MR, VCC2, and VCC1 pins - confirming absence of WDI, PFI, PFO, or RSTIN terminals.
What is the reset timeout period for MAX6717UKZGD3+T, and how is it set?
The MAX6717UKZGD3+T has a 210ms minimum reset timeout period, set by the 'D3' suffix in its part number per Maxim's Reset Timeout Period Suffix Guide - confirmed in Electrical Characteristics (tRP = 140ms min / 210ms typ / 280ms max) and Ordering Information tables.
Can MAX6717UKZGD3+T operate with VCC1 = 1.8V and VCC2 = 0.9V simultaneously?
Yes, MAX6717UKZGD3+T is explicitly designed for this configuration: VCC1 (1.575V threshold) monitors 1.8V I/O rails, and VCC2 (0.788V threshold) monitors 0.9V core supplies - validated by Typical Operating Circuit (page 1), Absolute Maximum Ratings, and Applications list.
Is the MR input on MAX6717UKZGD3+T internally pulled up, and what is its voltage threshold?
Yes, the MR input on MAX6717UKZGD3+T includes an internal 50kΩ pullup resistor to VCC1, and its logic threshold is VIL ≤ 0.3×VCC1 and VIH ≥ 0.7×VCC1 - specified in Electrical Characteristics (page 3) and Pin Description (page 7), eliminating need for external pullup components.
