Product details
Overview
MAX6717AUKTZD6+T from Maxim Integrated is a dual-supply ultra-low-voltage microprocessor supervisory circuit in 6-pin SOT23 package, monitoring VCC1 (factory-trimmed 4.625V threshold) and VCC2 (1.575V threshold), with 560ms reset timeout, open-drain active-low RST output, manual-reset input, and guaranteed reset validity down to VCC1 or VCC2 = 0.8V. It ensures reliable power-on reset and brownout detection in multivoltage embedded systems.
For engineers reviewing the MAX6717AUKTZD6+T datasheet, MAX6717AUKTZD6+T pinout, MAX6717AUKTZD6+T application, or MAX6717AUKTZD6+T equivalent, this page delivers verified specifications, validated pin functions, confirmed dual-supply monitoring behavior, exact reset timing, and real-world substitution guidance - all derived from Maxim's official MAX6715A–MAX6729A/MAX6797A datasheet Rev 6 (July 2019).
Technical Context
The MAX6717AUKTZD6+T implements independent voltage comparators for primary (VCC1) and secondary (VCC2) supplies, each with factory-trimmed thresholds and 0.5% hysteresis. Its reset logic asserts RST low when either supply falls below its threshold and holds for a fixed 560ms minimum timeout after recovery.
It features an internal 50kΩ pullup on MR, supports CMOS-level manual reset assertion, and guarantees correct reset state even during deep undervoltage (≥0.8V on either supply rail). No watchdog, RSTIN, PFI, or PFO functionality is included - confirmed by suffix "D6" (reset timeout) and "Z" (VCC2 threshold = 1.575V) per Maxim's Reset Voltage Threshold and Timeout Suffix Guides.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC1 Reset Threshold | 4.625V (factory-trimmed, ±125mV tolerance); ensures reliable reset assertion when main system supply drops below nominal 4.63V level. |
| VCC2 Reset Threshold | 1.575V (factory-trimmed, ±45mV tolerance); monitors auxiliary/IO supply rails such as 1.6V or 1.5V domains. |
| Reset Timeout Period | 560ms (min); provides sufficient hold time for microprocessor initialization and peripheral stabilization after power recovery. |
| Supply Current | 15µA (typ at VCC1 < 5.5V); enables long battery life in portable equipment without compromising supervision accuracy. |
| Operating Temperature | -40°C to +125°C; qualified for automotive under-hood, industrial control, and telecom infrastructure environments. |
| Reset Output Type | Open-drain active-low RST; requires external pullup, enabling level-shifting and wired-OR reset bus configurations. |
| Valid Reset Down To | VCC1 or VCC2 ≥ 0.8V; maintains deterministic reset state during severe brownout, preventing spurious release. |
Pinout & Package
MAX6717AUKTZD6+T is housed in a 6-pin SOT23 package (package code U6+1, outline 21-0058), with 1.6mm × 2.9mm footprint and 0.95mm height. Thermal resistance θJA = 115°C/W on multilayer board.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | RST / RST1 | Active-low open-drain reset output; asserted low when VCC1 < 4.625V or VCC2 < 1.575V; requires external pullup resistor. |
| 2 | GND | Analog/digital ground reference; must be connected directly to system ground plane for noise immunity and threshold stability. |
| 3 | MR | Active-low manual-reset input; internally pulled up to VCC1 (50kΩ); pulling low forces immediate reset assertion for 560ms post-release. |
| 4 | VCC2 | Secondary supply input; powers internal comparator for VCC2 monitoring and sets RST2 reference if present (not used in MAX6717A). |
| 5 | VCC1 | Primary supply input; powers device core, sets RST output reference, and enables MR pullup; valid from 0.8V to 5.5V. |
| 6 | NC | No connect; pin 6 is unused and must remain unconnected per Maxim's pin description for MAX6717A variant. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent supply monitoring | Simultaneous VCC1 (4.625V) and VCC2 (1.575V) threshold detection with separate comparators and hysteresis - eliminates need for discrete supervisors. |
| Guaranteed reset validity at low VCC | Outputs remain logically valid even when VCC1 or VCC2 drops to 0.8V - critical for fail-safe operation during deep brownout. |
| Low quiescent current | 15µA typical supply current enables integration into always-on battery-backed subsystems without significant drain. |
| Industrial temperature range | -40°C to +125°C operation supports deployment in harsh environments including automotive engine control units and base station power modules. |
| Open-drain RST with flexible interfacing | Allows direct connection to bidirectional μP reset pins and supports wired-OR reset buses across multiple ICs. |
Applications
| Industrial PLC Power Sequencing | Automotive Infotainment Core Supply Monitor |
|---|---|
Use Scenario: Monitoring 5V main and 1.6V IO supply rails in programmable logic controller backplane during cold start and load transients. IC Role / Device Role / Timing Role: Dual-threshold supervisor asserting reset until both rails stabilize above 4.625V and 1.575V, holding for 560ms to ensure FPGA configuration completion. Use Value: Prevents firmware lockup caused by premature μP release during slow-ramping 1.6V rail; eliminates need for discrete RC timers or additional supervisor ICs. |
Use Scenario: Ensuring safe boot of infotainment SoC by validating 5V system rail and 1.5V DDR IO supply before enabling clock distribution. IC Role / Device Role / Timing Role: Supervisory circuit providing synchronized reset pulse only after both supplies exceed factory-trimmed thresholds and remain stable for ≥560ms. Use Value: Meets AEC-Q100 functional safety requirements for supply sequencing integrity; reduces BOM count versus dual discrete supervisors. |
| Telecom Line Card Voltage Integrity | Portable Medical Device Power Management |
Use Scenario: Detecting undervoltage on +5V bias and +1.6V analog front-end supplies in optical line terminal modules exposed to thermal cycling. IC Role / Device Role / Timing Role: Fault detector triggering hard reset when either rail dips below spec, with 560ms timeout ensuring clean restart after transient dropout. Use Value: Maintains communication link integrity by preventing partial initialization during marginal supply conditions; operates reliably at +125°C ambient. |
Use Scenario: Managing power-up sequence for battery-powered ECG monitor using Li-ion (4.2V→3.0V) and LDO-regulated 1.6V analog sensor rail. IC Role / Device Role / Timing Role: Low-current (15µA) supervisor guaranteeing reset remains asserted until both rails are within tolerance, even as battery voltage decays to 3.0V. Use Value: Extends usable battery life while ensuring clinical-grade reliability; 0.8V reset validity prevents false release during end-of-life battery sag. |
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 | Same dual-monitor function and 6-pin SOT23 package, but with 140ms reset timeout (suffix D3) instead of 560ms (D6). | Suitable for faster-booting systems where shorter reset hold time is acceptable; not drop-in for timing-critical 560ms requirement. | Select only if system boot sequence completes within 140ms; verify μP reset deassertion timing margin. |
| TPS3808G33DBVR | TI dual-supply supervisor with 3.3V VDD1 threshold and 1.23V VDD2 threshold; 200ms fixed timeout; push-pull RST output. | Lacks 4.625V/1.575V exact threshold match; push-pull output requires redesign of reset bus termination. | Use only if thresholds can be revalidated and board layout allows replacement of open-drain RST with push-pull drive. |
Compared with MAX6717AUTTWD3+T, the MAX6717AUKTZD6+T provides 4× longer reset hold time for robust initialization; compared with TPS3808G33DBVR, it offers precise Maxim-trimmed thresholds and open-drain flexibility but requires different reset bus design.

FAQ
What is the exact reset threshold voltage for VCC1 on MAX6717AUKTZD6+T?
The MAX6717AUKTZD6+T has a factory-trimmed VCC1 reset threshold of 4.625V (typical), with ±125mV tolerance (4.500V to 4.750V) over temperature. This value is fixed by the "T" suffix in the part number per Maxim's Reset Voltage Threshold Suffix Guide and is confirmed in the Electrical Characteristics table of the official datasheet.
Does MAX6717AUKTZD6+T support watchdog timer functionality?
No, MAX6717AUKTZD6+T does not include watchdog timer functionality. The "W" suffix denotes watchdog capability; MAX6717AUKTZD6+T lacks "W" and is confirmed in the Pin Description table to omit WDI pin functionality. Only variants like MAX6721A–MAX6729A/MAX6797A support watchdog inputs.
What is the reset timeout period for MAX6717AUKTZD6+T, and is it adjustable?
The MAX6717AUKTZD6+T has a fixed minimum reset timeout period of 560ms, indicated by the "D6" suffix. This value is factory-programmed and not adjustable via external components. The datasheet specifies tRP = 560ms (min), 840ms (typ), and 1120ms (max) across temperature and voltage conditions.
Is MAX6717AUKTZD6+T pin-compatible with other MAX67xxA variants in the same package?
MAX6717AUKTZD6+T shares the 6-pin SOT23 (U6+1) package with other MAX6717x variants, but pin compatibility is limited to identical suffix groups. Pin 6 is NC in MAX6717AUKTZD6+T, whereas MAX6728A/MAX6729A use pin 6 for PFI - making them electrically incompatible despite identical footprint.
What is the maximum supply voltage rating for MAX6717AUKTZD6+T?
The MAX6717AUKTZD6+T supports VCC1 and VCC2 supply voltages from 0.8V to 5.5V (absolute maximum rating: -0.3V to +6V). Operation above 5.5V risks permanent damage; the 5.5V limit is specified in the Absolute Maximum Ratings table and applies to both supply inputs independently.
