Product details
Overview
MAX6717AUKLTD3+T from Maxim Integrated is a dual-supply ultra-low-voltage microprocessor supervisory circuit in 6-pin SOT23 package, monitoring VCC1 (1.8V–5.0V) and VCC2 (0.9V–3.3V) with factory-trimmed reset thresholds, 140ms minimum reset timeout, open-drain active-low RST output, and manual-reset input - deployed in telecom power systems to ensure reliable boot sequencing and brownout recovery.
For engineers reviewing the MAX6717AUKLTD3+T datasheet, MAX6717AUKLTD3+T pinout, MAX6717AUKLTD3+T application, or MAX6717AUKLTD3+T equivalent, key selection criteria include dual-rail voltage monitoring capability, guaranteed reset validity down to VCC1/VCC2 = 0.8V, low 14μA typical supply current at 3.6V, and compatibility with industrial temperature range (−40°C to +125°C).
Technical Context
The MAX6717AUKLTD3+T integrates two independent voltage comparators with hysteresis (0.5% of threshold), a 140ms reset timeout timer, and a manual-reset input with internal 50kΩ pullup to VCC1. It asserts an open-drain RST output when either VCC1 or VCC2 falls below its factory-set threshold (VTH1 = 2.550V–2.700V, VTH2 = 1.350V–1.425V), maintaining reset for ≥140ms after both supplies recover.
No watchdog, RSTIN, PFI, or PFO functions are implemented in this variant - confirmed by suffix "D3" (140ms timeout) and "UKLT" (6-pin SOT23, open-drain RST, manual reset, dual-supply only). Pin configuration excludes WDI, RSTIN, PFI, PFO, and RST2 terminals per MAX6717A pin mapping.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC1 Reset Threshold | 2.550V to 2.700V (factory-trimmed, falling edge; supports 2.5V/3.3V system rails) |
| VCC2 Reset Threshold | 1.350V to 1.425V (factory-trimmed, falling edge; enables core voltage monitoring at 1.2V–1.35V) |
| Reset Timeout Period | 140ms minimum (suffix D3; ensures sufficient hold time for slow-start DC-DC converters) |
| Supply Current | 14μA typical at 3.6V (enables battery-backed operation in portable equipment) |
| Operating Temperature | −40°C to +125°C (AEC-Q100 qualified variants exist; this part meets full industrial grade) |
| Reset Output Type | Open-drain active-low RST (requires external pullup; compatible with bidirectional μP reset pins) |
| Valid Reset Down To | VCC1 or VCC2 ≥ 0.8V (guaranteed logic state integrity during deep brownout conditions) |
Pinout & Package
MAX6717AUKLTD3+T is housed in a 6-pin SOT23-6 package (package code U6+1), with 1.6mm × 2.8mm footprint and 0.95mm height. Thermal resistance θJA = 115°C/W on multilayer board.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | RST | Active-low open-drain reset output; asserted when VCC1 or VCC2 drops below threshold; requires external pullup resistor |
| 2 | GND | Ground reference for all internal comparators and timing circuits |
| 3 | MR | Active-low manual-reset input; internal 50kΩ pullup to VCC1; 1µs minimum pulse width required |
| 4 | VCC2 | Secondary supply input (0.9V–3.3V); powers internal VCC2 comparator and sets RST2 reference if present (not used in MAX6717A) |
| 5 | VCC1 | Primary supply input (1.8V–5.0V); powers device core, sets RST output reference, and pulls up MR |
| 6 | NC | No connect; unused pin (confirmed by MAX6717A pin table - no WDI, RSTIN, PFI, or PFO assigned) |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent voltage monitoring | Simultaneous supervision of primary (VCC1) and secondary (VCC2) rails without external components |
| Factory-trimmed precision thresholds | VTH1 = 2.550–2.700V and VTH2 = 1.350–1.425V with ±1.5% tolerance over temperature |
| Immunity to short VCC transients | Rejects <20µs negative glitches at ≥100mV overdrive - prevents spurious resets in noisy power environments |
| Low-power operation | 14μA typical ICC at 3.6V enables >10-year battery life in always-on monitoring applications |
| Guaranteed reset assertion at low VCC | Valid RST logic state maintained even when VCC1 or VCC2 drops to 0.8V - critical for graceful shutdown |
Applications
| Telecom Power Management | Industrial PLC I/O Modules |
|---|---|
|
Use Scenario: Monitoring dual-rail power (3.3V control logic + 1.2V FPGA core) in 48V-powered telecom line cards subject to hot-swap transients and partial brownouts. IC Role / Device Role / Timing Role: Dual-supply supervisor asserting open-drain RST to hold processor in reset until both rails stabilize post-insertion. Use Value: Prevents firmware corruption during hot-swap by enforcing 140ms minimum reset hold time after VCC1/VCC2 recovery. |
Use Scenario: Ensuring deterministic startup of programmable logic controllers with isolated 24V field power and 3.3V logic supply in factory automation cabinets. IC Role / Device Role / Timing Role: Supervising VCC1 (3.3V logic rail) and VCC2 (24V-to-5V converted rail) to guarantee clean boot before I/O initialization. Use Value: Eliminates need for discrete RC reset circuits while supporting −40°C to +125°C ambient operation in uncooled enclosures. |
| Medical Diagnostic Imaging Subsystems | Automotive ADAS Camera Modules |
|
Use Scenario: Securing power-up sequence of high-speed ADCs and FPGAs in portable ultrasound units powered by Li-ion batteries with variable discharge profiles. IC Role / Device Role / Timing Role: Monitoring battery-derived 3.3V analog supply and regulated 1.8V digital core to prevent partial initialization under low-battery conditions. Use Value: 0.8V valid-reset floor ensures reset remains asserted until battery recovers above critical threshold - avoids silent data corruption. |
Use Scenario: Validating dual power domains (5V image sensor bias + 1.2V ISP core) in automotive surround-view cameras exposed to load-dump and cold-crank events. IC Role / Device Role / Timing Role: Dual-rail supervisor triggering hardware reset upon simultaneous drop of VCC1 and VCC2 during cranking. Use Value: 14μA quiescent current minimizes parasitic drain on vehicle battery during extended parking modes. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-supply supervisory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6715AUTTWD3+T | 5-pin SOT23-5; identical VTH1/VTH2 thresholds and 140ms timeout; no MR input | Used where manual reset is unnecessary and PCB space is constrained | Select when MR functionality is omitted and footprint reduction is prioritized |
| TLV809E25DBZR | Single-supply supervisor (2.5V threshold only); 140ms timeout; SOT23-3; no VCC2 monitoring | Requires separate IC for secondary rail supervision; higher BOM count | Choose only for cost-sensitive single-rail systems where dual monitoring is not required |
Compared with MAX6717AUKLTD3+T, MAX6715AUTTWD3+T saves one pin but removes manual reset capability, while TLV809E25DBZR reduces package size yet forces duplication for dual-rail coverage - making MAX6717AUKLTD3+T the optimal balance of integration, diagnostics, and layout efficiency for compact dual-voltage systems.

FAQ
What is the exact reset threshold voltage for VCC1 and VCC2 on the MAX6717AUKLTD3+T?
The MAX6717AUKLTD3+T has factory-trimmed VCC1 reset threshold of 2.550V to 2.700V (R-suffix) and VCC2 threshold of 1.350V to 1.425V (I-suffix), specified at falling edge with ±1.5% tolerance over −40°C to +125°C. These values are fixed per device ordering code and cannot be adjusted externally.
Does the MAX6717AUKLTD3+T support watchdog timer functionality?
No, the MAX6717AUKLTD3+T does not include watchdog timer functionality. Its ordering suffix "UKLT" identifies it as a dual-supply supervisor with manual reset and open-drain RST output only - WDI, RSTIN, PFI, and PFO pins are unassigned and NC on this variant.
Can the MAX6717AUKLTD3+T monitor a 1.0V supply rail?
Yes - the MAX6717AUKLTD3+T supports VCC2 monitoring down to 0.9V, and its VCC2 threshold of 1.350V–1.425V is appropriate for supervising 1.0V rails with margin. However, the device itself requires VCC2 ≥ 0.9V to operate; for sub-0.9V rails, consider MAX6720A with RSTIN input.
What is the maximum allowable load on the open-drain RST output of the MAX6717AUKLTD3+T?
The MAX6717AUKLTD3+T RST output sinks up to 3.2mA at VCC1 ≥ 4.5V with VOL ≤ 0.4V. For reliable operation, external pullup should limit current to ≤1mA (e.g., 4.7kΩ to 3.3V), ensuring VOL stays below 0.3V and enabling direct interface with bidirectional μP reset pins.
Is the MAX6717AUKLTD3+T qualified for automotive applications?
The MAX6717AUKLTD3+T is rated for −40°C to +125°C operation and meets industrial reliability standards, but it is not AEC-Q100 qualified. For automotive use, select the pin-compatible MAX6719AUTTWD3+T (AEC-Q100 Grade 2) or MAX6729AUKLTD3+T (AEC-Q100 Grade 1), which share identical electrical specs and package.
