Product details
Overview
MAX6762TATAD3 from Maxim Integrated is a dual-voltage window detector IC that monitors both VCC (3.3V nominal) and VCC2 (adjustable down to 0.5V) for undervoltage and overvoltage conditions, featuring independent UV/OV open-drain outputs, latched OV output, manual reset input, and 100ms minimum reset timeout. It operates across -40°C to +125°C and draws only 13µA typical supply current.
For engineers reviewing the MAX6762TATAD3 datasheet, MAX6762TATAD3 pinout, MAX6762TATAD3 application, or MAX6762TATAD3 equivalent, this device is selected for high-reliability dual-rail power monitoring in automotive ECUs, industrial PLCs, and telecom DC-DC modules where latch-on-fault behavior and extended temperature operation are required.
Technical Context
The MAX6762TATAD3 implements two independent voltage comparators with factory-trimmed thresholds for VCC (3.3V ±5%/±10%/±15% selectable via SET pin) and externally adjustable VCC2 (via resistor divider targeting 0.4255V at VCC2 pin). Its OVLATCH input enables persistent fault reporting until cleared, distinguishing it from non-latching variants like MAX6759.
It uses an internal bandgap reference and hysteresis of 0.7% to reject noise-induced false triggers. The 100ms timeout (D3 suffix) applies only to RESET/UV deassertion after recovery; OV asserts/deasserts immediately without delay, and latching overrides timing behavior on overvoltage events.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Threshold | 3.3V nominal with ±5%, ±10%, or ±15% window selectable via SET pin - enables precise tolerance matching for I/O rail monitoring |
| VCC2 Threshold | Externally adjustable from 0.5V to 6.0V using resistor divider - supports custom core or analog supply monitoring |
| Supply Current | 13µA typical at VCC = 3.6V - ensures minimal impact on battery-backed or low-power systems |
| Reset Timeout | 100ms minimum (D3 suffix) - guarantees sufficient hold time for microprocessor initialization after power recovery |
| Operating Temp | -40°C to +125°C - qualified for under-hood automotive and industrial edge environments |
| Output Type | Open-drain UV and OV; push-pull RESET - allows flexible logic-level translation and wired-OR fault bus implementation |
| Latch Function | OVLATCH-controlled latched OV output - maintains fault state until explicitly cleared, critical for safety-critical diagnostics |
Pinout & Package
MAX6762TATAD3 is housed in an 8-pin TDFN-EP package (3mm × 3mm, 0.75mm height) with exposed pad connected to GND for thermal and EMI performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - VCC | Power Input & Primary Monitor Rail | Powers device and serves as first monitored voltage (3.3V nominal); valid operation down to 1.0V |
| 2 - GND | Ground Reference | Analog/digital ground return; EP pad internally tied to GND for thermal dissipation |
| 3 - VCC2 | Secondary Monitor Rail Input | Input for second voltage monitor; accepts 0–6.0V; threshold set by external divider to 0.4255V |
| 4 - MR | Active-Low Manual Reset | Asserts UV/RESET when pulled low; 26kΩ internal pullup enables button-only interface |
| 5 - SET | Window Threshold Select | GND = ±5%, VCC = ±10%, VCC/2 = ±15% - configures detection hysteresis without external components |
| 6 - UV | Undervoltage Output | Open-drain active-low output; asserts when VCC or VCC2 falls below respective UVTH; deasserts after 100ms timeout |
| 7 - OV | Overvoltage Output | Open-drain active-low output; asserts immediately on OV condition; latched if OVLATCH = high |
| 8 - OVLATCH | Latch Control Input | High = latch OV output until cleared; low = transparent mode; high-impedance input requires external pullup/pulldown |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent voltage monitoring | Simultaneously supervises main I/O rail (VCC = 3.3V) and configurable core/analog rail (VCC2), eliminating need for two discrete supervisors |
| Latched overvoltage reporting | OVLATCH pin enables persistent fault flagging - essential for diagnostic logging in automotive ASIL-B systems |
| Factory-trimmed ±5%/±10%/±15% windows | SET pin selects hysteresis without trimming resistors - reduces BOM count and layout area vs. adjustable solutions |
| 100ms guaranteed reset timeout | D3 suffix ensures minimum 100ms reset pulse width even at temperature extremes - meets JEDEC JESD78 latch-up immunity timing |
| Low 13µA quiescent current | Enables always-on monitoring in battery-powered telematics units without compromising runtime |
| Extended -40°C to +125°C operation | Validated across full automotive temperature range - suitable for engine control, ADAS, and industrial motor drives |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-voltage window detector applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6761TATAD3 | Identical pinout, electrical specs, and features; differs only in internal VCC2 trim (same TA suffix = 3.3V/ADJ) | No functional difference; used interchangeably in same designs | Select when MAX6762TATAD3 is unavailable; identical qualification and reliability data |
| TPS3808G33DBVR | Single-supply only (3.3V), no VCC2 input or OVLATCH; 200ms timeout; SOT-23-6 package | Lacks dual-rail monitoring and latch functionality - unsuitable for systems requiring core+I/O supervision | Consider only for cost-sensitive single-rail applications where latch and second rail are unnecessary |
Compared with MAX6762TATAD3, MAX6761TATAD3 offers identical dual-rail supervision and latch capability in the same TDFN package, while TPS3808G33DBVR provides lower-cost single-rail monitoring but cannot replace the fault-latching or VCC2 monitoring functions required in safety-critical dual-supply systems.

FAQ
What voltage rails does the MAX6762TATAD3 monitor?
The MAX6762TATAD3 monitors two independent voltage rails: VCC (factory-trimmed to 3.3V nominal) and VCC2 (externally adjustable from 0.5V to 6.0V via resistor divider). Both rails are checked for undervoltage and overvoltage conditions, with independent UV and OV outputs. This dual-monitoring capability makes MAX6762TATAD3 ideal for systems with separate I/O and core supplies.
How is the window threshold adjusted on the MAX6762TATAD3?
The MAX6762TATAD3 uses the SET pin to select the undervoltage/overvoltage window tolerance: connect SET to GND for ±5%, to VCC for ±10%, or bias to VCC/2 for ±15%. This configuration applies to both VCC and VCC2 thresholds. No external resistors are needed for hysteresis adjustment - the window is set entirely by the SET pin state, simplifying design and reducing component count.
Does the MAX6762TATAD3 provide latched overvoltage reporting?
Yes, the MAX6762TATAD3 includes an OVLATCH input that controls latching behavior of the OV output. When OVLATCH is driven high, the OV output remains asserted after an overvoltage event until OVLATCH is pulled low. This latch-on-fault feature is critical for diagnostic systems needing persistent fault flags across power cycles - a capability not present in non-latching supervisors like MAX6759.
What is the reset timeout behavior of the MAX6762TATAD3?
The MAX6762TATAD3 features a 100ms minimum reset timeout period (D3 suffix), meaning the RESET and UV outputs remain asserted for at least 100ms after VCC or VCC2 recovers above their undervoltage thresholds. This guaranteed hold time ensures reliable microprocessor initialization. The OV output has no timeout - it deasserts immediately when the overvoltage condition clears, unless latched via OVLATCH.
What package and temperature grade is the MAX6762TATAD3 supplied in?
The MAX6762TATAD3 is supplied in an 8-pin TDFN-EP package (3mm × 3mm) with exposed pad connected to GND, and is specified for operation from -40°C to +125°C. This automotive-grade temperature range and compact thermally enhanced package make MAX6762TATAD3 suitable for space-constrained, high-reliability applications including engine control, industrial automation, and telecom infrastructure.
