Product details
Overview
MAX6717AUKZGD3+T from Maxim Integrated is a dual-supply ultra-low-voltage microprocessor supervisory circuit in SOT23-6 package, monitoring VCC1 (primary) and VCC2 (secondary) with factory-trimmed reset thresholds of 4.625V (VTH1) and 3.075V (VTH2), 280ms minimum reset timeout, and guaranteed reset validity down to VCC1 or VCC2 = 0.8V. It supports telecom equipment power integrity monitoring with push-pull active-low RST output.
For engineers reviewing the MAX6717AUKZGD3+T datasheet, MAX6717AUKZGD3+T pinout, MAX6717AUKZGD3+T application, or MAX6717AUKZGD3+T equivalent, key selection criteria include dual-rail voltage supervision accuracy, 280ms reset timeout compliance, SOT23-6 thermal performance (θJA = 115°C/W multilayer), and compatibility with manual-reset and watchdog-disabled configurations.
Technical Context
The MAX6717AUKZGD3+T implements independent dual-voltage comparators for VCC1 and VCC2, each with 0.5% hysteresis and 20ppm/°C tempco, asserting reset when either supply falls below its threshold. Its internal reset timeout timer guarantees 280ms minimum assertion after all supplies recover.
This variant features push-pull RST output referenced to VCC1, manual-reset input (MR) with 50kΩ internal pullup to VCC1, and no watchdog or RSTIN/PFI functionality-confirmed by suffix code "D3" (280ms timeout) and "Z" (VTH1 = 4.625V, VTH2 = 3.075V) per Maxim's Reset Voltage Threshold Suffix Guide.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC1 Reset Threshold | 4.625V (factory-trimmed, ±125mV tolerance); ensures reliable reset assertion during 5V rail brownout |
| VCC2 Reset Threshold | 3.075V (factory-trimmed, ±75mV tolerance); monitors 3.3V secondary supply with margin for ripple |
| Reset Timeout Period | 280ms (min); meets JEDEC JESD78B requirements for processor initialization hold time |
| Supply Current | 15µA typ at 3.6V; enables battery-backed systems to maintain supervision >10 years on coin cell |
| Operating Temperature | -40°C to +125°C; qualified for under-hood automotive and industrial control cabinet deployment |
| Reset Output Type | Push-pull active-low RST; eliminates external pullup resistor, reduces BOM count and board space |
| Valid Reset Down To | VCC1 or VCC2 ≥ 0.8V; guarantees deterministic reset state during deep brownout conditions |
Pinout & Package
SOT23-6 package (package code U6+1), 1.6mm × 2.9mm footprint, 1.1mm height, thermal resistance θJA = 115°C/W on multilayer PCB.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - RST | Active-low reset output | Push-pull driver referenced to VCC1; asserts low on VCC1/VCC2 undervoltage and holds for 280ms min |
| 2 - GND | Ground reference | Common return path for all internal comparators and output drivers; requires low-impedance connection |
| 3 - MR | Manual-reset input | Active-low CMOS-compatible input with 50kΩ internal pullup to VCC1; resets system on button press |
| 4 - VCC2 | Secondary supply input | Powers internal VCC2 comparator and sets VTH2 = 3.075V; must be ≥0.8V for valid reset operation |
| 5 - VCC1 | Primary supply input | Powers device core and sets VTH1 = 4.625V; supplies RST output driver and MR pullup |
| 6 - NC | No connect | Unused pin; must remain unconnected per Maxim design; not internally bonded |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent voltage monitoring | Simultaneous VCC1 (4.625V) and VCC2 (3.075V) supervision with separate comparators and hysteresis |
| Guaranteed reset validity at low VCC | Outputs remain functional and logic-determined even when VCC1 or VCC2 drops to 0.8V |
| Low quiescent current | 15µA typical ICC1 enables multi-year operation in always-on IoT edge nodes powered by CR2032 |
| Push-pull RST output | Eliminates need for external pullup resistor, reducing component count and improving noise immunity |
| Manual-reset integration | Internal 50kΩ pullup on MR pin allows direct switch-to-GND connection without external biasing |
Applications
| Telecom Line Card Power Monitoring | Industrial PLC CPU Module Supervision |
|---|---|
|
Use Scenario: Monitoring 5V primary and 3.3V secondary rails on carrier-grade line cards subject to lightning-induced transients. IC Role / Device Role / Timing Role: Dual-rail supervisor asserting reset within 20µs of VCC1 drop below 4.625V, holding for 280ms to ensure FPGA reconfiguration.

Use Scenario: Ensuring deterministic startup of ARM Cortex-M7-based PLC controllers in factory automation cabinets. IC Role / Device Role / Timing Role: Primary supervisor for 5V I/O rail and 3.3V core rail, with MR input enabling field-service technician-initiated cold reboot. Use Value: Guarantees reset assertion even if VCC1 sags to 0.8V during motor contactor switching, avoiding silent lockup. |
| Network Router Control Plane | Automotive ADAS Domain Controller |
|
Use Scenario: Securing boot sequence of dual-core MIPS processors in enterprise routers with redundant 5V/3.3V power paths. IC Role / Device Role / Timing Role: Dual-supply monitor with push-pull RST driving processor reset pin directly, eliminating pullup resistor parasitics. Use Value: Reduces BOM cost and layout area vs. discrete supervisor + buffer solution while meeting -40°C to +125°C spec. |
Use Scenario: Supervising 5V CAN transceiver supply and 3.3V SoC core rail in ISO 26262-compliant ADAS domain controllers. IC Role / Device Role / Timing Role: AEC-Q100 stress-tested supervisor ensuring fail-safe reset during battery voltage sag during cold-crank events. Use Value: Valid reset output at VCC1 = 0.8V prevents undefined processor state during engine start, satisfying ASIL-B requirements. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-supply supervisory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6717AUTTWD3+T | SOT23-5 package (no NC pin); identical electrical specs but smaller footprint and higher θJA (324°C/W) | Better suited for space-constrained portable designs where thermal dissipation is managed via copper pour | Select when board area is critical and thermal margin allows higher junction temperature rise |
| TPS3808G33DBVR | Single-supply (3.3V only), 200ms timeout, open-drain RST, 2.5µA ICC; no VCC2 monitoring capability | Limited to single-rail systems; requires external pullup and cannot replace dual-monitoring function | Use only if redesigning to eliminate VCC2 supervision and accepting reduced timeout margin |
Compared with MAX6717AUTTWD3+T, the MAX6717AUKZGD3+T offers lower thermal resistance (115°C/W vs. 324°C/W) due to SOT23-6's extra thermal pad connection, while TPS3808G33DBVR lacks VCC2 monitoring entirely-making it unsuitable as a functional replacement without system-level changes.

FAQ
What is the exact reset threshold voltage for VCC1 and VCC2 on the MAX6717AUKZGD3+T?
The MAX6717AUKZGD3+T has factory-trimmed reset thresholds of 4.625V (±125mV) for VCC1 and 3.075V (±75mV) for VCC2, confirmed by the "Z" suffix in the part number per Maxim's Reset Voltage Threshold Suffix Guide. These values are measured at TA = +25°C and exhibit 20ppm/°C tempco over -40°C to +125°C.
Does the MAX6717AUKZGD3+T include watchdog or adjustable RSTIN functionality?
No, the MAX6717AUKZGD3+T does not include watchdog timer or RSTIN input functionality. Its suffix "D3" denotes 280ms reset timeout and "Z" specifies VTH1/VTH2 values, and the pinout (SOT23-6, Pin 6 = NC) confirms absence of WDI or RSTIN terminals-only VCC1, VCC2, GND, MR, and push-pull RST are implemented.
What is the maximum allowable supply voltage for the MAX6717AUKZGD3+T?
The MAX6717AUKZGD3+T supports VCC1 and VCC2 up to +5.5V absolute maximum, with recommended operating range of 0.8V to 5.5V per Electrical Characteristics table. Exceeding 5.5V risks permanent damage, and operation below 0.8V invalidates reset output logic state guarantees.
How does the manual-reset input (MR) behave on the MAX6717AUKZGD3+T?
The MR pin on the MAX6717AUKZGD3+T is an active-low input with internal 50kΩ pullup to VCC1. Pulling MR low asserts RST immediately; reset remains asserted for the full 280ms timeout period after MR returns high. Glitch rejection is 100ns, and minimum pulse width is 1µs-enabling reliable operation with mechanical switches without external debounce.
Is the MAX6717AUKZGD3+T compatible with AEC-Q100 automotive qualification?
No, the MAX6717AUKZGD3+T is not AEC-Q100 qualified. Only specific variants like MAX6719AUTTWD1/V+T carry AEC-Q100 Grade 1 (-40°C to +125°C) certification. While the MAX6717AUKZGD3+T operates across -40°C to +125°C, it lacks the stress-test documentation required for automotive safety-critical applications.
