Product details
Overview
MAX6717UKZWD3 from Maxim Integrated is a dual-voltage microprocessor supervisory circuit in 5-pin SOT23 package, monitoring VCC1 (1.62V threshold) and VCC2 (0.788V threshold) with 210ms reset timeout, push-pull RST output, manual reset input, and guaranteed reset validity down to VCC1 or VCC2 = 0.8V - used in portable battery-operated systems for reliable power-up sequencing and brownout protection.
For engineers reviewing the MAX6717UKZWD3 datasheet, MAX6717UKZWD3 pinout, MAX6717UKZWD3 application, or MAX6717UKZWD3 equivalent, key selection criteria include dual-supply monitoring range (1.62V/0.788V), 210ms min timeout, push-pull reset drive capability, MR input compatibility with TTL/CMOS logic, and operation over –40°C to +85°C industrial temperature range.
Technical Context
The MAX6717UKZWD3 integrates two independent voltage comparators with factory-trimmed thresholds (VTH1 = 1.62V, VTH2 = 0.788V) and a digital reset timeout timer. It asserts an active-low push-pull RST output when either supply falls below its threshold and holds reset for ≥210ms after both supplies recover.
It features a manual reset input (MR) with internal 50kΩ pullup to VCC1, supports reset assertion via MR low pulse ≥1µs, and guarantees valid RST logic state as long as VCC1 or VCC2 remains ≥0.8V - enabling robust operation during deep brownout conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC1 Reset Threshold | 1.62V (typ), factory-trimmed for precise 1.62V primary supply monitoring |
| VCC2 Reset Threshold | 0.788V (typ), factory-trimmed for accurate 0.788V secondary supply monitoring |
| Reset Timeout Period | 210ms (min), ensures sufficient hold time for µP initialization after power recovery |
| Supply Current | 14µA (typ) at 3.6V, enables ultra-low-power operation in battery-critical applications |
| Operating Temperature | –40°C to +85°C, qualified for industrial and extended-temperature embedded systems |
| Reset Output Type | Push-pull active-low RST, eliminates need for external pullup and drives directly into µP reset pin |
| MR Input Logic | TTL/CMOS-compatible with 0.3×VCC1 low / 0.7×VCC1 high thresholds and 1µs minimum pulse width |
Pinout & Package
MAX6717UKZWD3 is housed in a 5-pin SOT23-5 package (2.9mm × 1.6mm × 1.1mm), optimized for space-constrained PCB layouts in portable electronics. Pin 1 is marked with dot; pin numbering follows standard SOT23 convention (counterclockwise from mark).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | RST | Active-low push-pull reset output; drives low on fault and remains low ≥210ms after recovery |
| 2 | GND | Ground reference for all internal comparators, timers, and I/O circuits |
| 3 | MR | Active-low manual reset input; internal 50kΩ pullup to VCC1, accepts TTL/CMOS logic levels |
| 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 VCC1 (1.62V) and VCC2 (0.788V) supervision with separate comparators and hysteresis |
| Guaranteed reset validity down to 0.8V | Ensures correct RST logic state even during severe brownout - no external pull-down needed |
| Push-pull RST output | Eliminates external pullup resistor, reduces BOM count, and provides stronger drive than open-drain |
| Manual reset with internal pullup | 50kΩ internal pullup to VCC1 allows direct switch-to-GND connection without external components |
| Low 14µA supply current | Minimizes quiescent drain on battery rails - critical for always-on or sleep-mode portable devices |
Applications
| Portable Battery-Powered Devices | Industrial Control Systems |
|---|---|
Use Scenario: Power management in handheld medical monitors with dual-core SoC requiring independent 1.6V core and 3.3V I/O rail supervision. IC Role / Device Role / Timing Role: Dual-supply supervisor asserting synchronized reset across processor and peripherals during battery sag or charger disconnect. Use Value: Prevents corrupted memory writes and firmware lockup by enforcing 210ms minimum reset hold time after VCC1/VCC2 recovery. |
Use Scenario: PLC I/O module with isolated 5V logic and 24V field-side supplies needing coordinated reset on undervoltage events. IC Role / Device Role / Timing Role: Monitoring 5V logic rail (VCC1) and 3.3V auxiliary rail (VCC2) to trigger system-wide reset before logic errors propagate. Use Value: Factory-trimmed 1.62V/0.788V thresholds eliminate calibration overhead; –40°C to +85°C rating ensures reliability in uncontrolled environments. |
| Telecom Edge Equipment | Embedded Computing Modules |
Use Scenario: Small-cell base station radio card with 1.2V FPGA core and 1.8V transceiver supply subject to thermal derating. IC Role / Device Role / Timing Role: Supervising both rails to detect simultaneous or staggered brownouts and assert clean reset before configuration loss. Use Value: Immunity to short VCC transients (<20µs at 100mV overdrive) prevents spurious resets during switching noise events. |
Use Scenario: RISC-V-based edge AI module using 1.0V CPU core and 1.8V DDR interface, requiring deterministic boot sequence. IC Role / Device Role / Timing Role: Providing deterministic reset timing and MR input for JTAG-initiated debug reset without modifying PCB layout. Use Value: Push-pull RST output interfaces directly to bidirectional µP reset pins without series resistor contention risk. |
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-T | 6-pin SOT23-6, open-drain RST output, same VTH1/VTH2 thresholds and 210ms timeout | Requires external pullup resistor; better suited for systems needing level-shiftable reset or shared bus reset lines | Select when open-drain flexibility or additional pin for future feature enablement is required |
| TPS3808G16DBVR | Single-supply monitor (1.6V threshold only), 200ms timeout, 1.6µA quiescent current, SOT23-5 | Lacks VCC2 monitoring - requires second supervisor or discrete solution for dual-rail systems | Choose only if monitoring one rail suffices and ultra-low ICC (1.6µA vs. 14µA) is critical |
Compared with MAX6717UKZWD3, MAX6715UTLTD3-T offers open-drain flexibility but adds layout complexity; TPS3808G16DBVR reduces power consumption significantly but cannot replace dual-monitoring functionality without system redesign.

FAQ
What is the exact reset threshold voltage for VCC1 on MAX6717UKZWD3?
The MAX6717UKZWD3 has a factory-trimmed VCC1 reset threshold of 1.62V (typical), with guaranteed range 1.575V to 1.665V across temperature and process variation. This value is fixed by the 'W' suffix in the part number per Maxim's Reset Voltage Threshold Suffix Guide and applies specifically to the MAX6717UKZWD3 variant.
Does MAX6717UKZWD3 support monitoring a third voltage rail?
No, MAX6717UKZWD3 is a dual-supply supervisor and does not include RSTIN or PFI inputs. Only MAX6719–MAX6729 variants in the family provide triple-voltage monitoring capability. The MAX6717UKZWD3 monitors only VCC1 and VCC2 as defined by its pinout and functional description.
What is the reset timeout period for MAX6717UKZWD3 and how is it set?
The MAX6717UKZWD3 has a minimum reset timeout period of 210ms, set by the 'D3' suffix in the part number per Maxim's Reset Timeout Period Suffix Guide. This is a factory-programmed, non-adjustable delay that begins after VCC1 and VCC2 both rise above their respective thresholds and ensures sufficient hold time for microprocessor initialization.
Can MAX6717UKZWD3 operate with VCC2 higher than VCC1?
Yes, MAX6717UKZWD3 is designed to operate with either VCC1 or VCC2 as the dominant supply. When VCC2 > VCC1, the device is powered from VCC2 and VCC2 serves as the reference for the RST output driver. The supervisory function remains fully operational regardless of which supply is higher, as confirmed in the Absolute Maximum Ratings and Detailed Description sections.
Is the MR input on MAX6717UKZWD3 internally pulled up, and what is the resistance value?
Yes, the MR input on MAX6717UKZWD3 includes an internal pullup resistor to VCC1 with a nominal value of 50kΩ (range 25kΩ to 80kΩ). This allows direct connection of a momentary switch from MR to GND for manual reset without external components, and the input accepts standard TTL/CMOS logic levels per datasheet specifications.
