Product details
Overview
MAX6762TATAD3+T from Analog Devices is a dual-voltage window detector IC monitoring both VCC (3.3V nominal) and VCC2 (adjustable down to 0.9V), with independent undervoltage/overvoltage outputs, ±15% selectable window tolerance, 100ms minimum reset timeout, latched overvoltage function, and manual reset input. It operates across -40°C to +125°C and supports telecom power rail supervision.
For engineers reviewing the MAX6762TATAD3+T datasheet, MAX6762TATAD3+T pinout, MAX6762TATAD3+T application, or MAX6762TATAD3+T equivalent, key selection criteria include dual-supply monitoring capability, latch-enabled OV response for fault persistence, factory-trimmed 3.3V/adjustable VCC2 thresholds, TDFN-8 package compatibility, and AEC-Q100 qualification for automotive-grade reliability.
Technical Context
The MAX6762TATAD3+T implements two independent voltage comparators with internal reference and programmable hysteresis (0.7%), enabling simultaneous detection of UV/OV events on VCC (3.3V nominal) and externally adjustable VCC2 (via resistor divider to 0.4255V). Its OVLATCH pin provides transparent or latched OV output behavior based on logic level.
It features a 100ms minimum reset timeout period (D3 suffix), SET pin biasing for ±5%/±10%/±15% window selection, MR input with 4µs minimum pulse width and 26kΩ internal pullup, and guaranteed operation with VCC ≥ 1.4V while maintaining correct output state down to VCC = 1.0V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Nominal | 3.3V - factory-trimmed primary supply monitoring point |
| VCC2 Range | Adjustable from 0.9V to 3.3V - set via external resistor divider to 0.4255V reference |
| Window Tolerance | ±15% - selected by biasing SET pin to VCC/2; enables robust noise margin |
| Reset Timeout | 100ms min - ensures stable microprocessor reset after brownout recovery |
| Supply Current | 13µA typ at 3.6V - enables ultra-low-power system monitoring in always-on circuits |
| Operating Temp | -40°C to +125°C - qualified for under-hood automotive and industrial environments |
| OV Latch Control | OVLATCH pin - high-level assertion locks OV output until cleared, critical for fault logging |
Pinout & Package
MAX6762TATAD3+T is housed in an 8-pin TDFN package (package code T833+2, outline 21-0137) with exposed pad connected to GND. Thermal resistance θJA is 41°C/W on multilayer board.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 MR | Active-low manual reset input | Asserts UV and RESET outputs; internally pulled up to VCC (26kΩ); 4µs minimum pulse width |
| 2 OVLATCH | Overvoltage latch control | High = latch OV output; low = clear latch; high-impedance input requiring external pullup/pulldown |
| 3 UV | Active-low undervoltage output | Push-pull configuration; asserts when VCC or VCC2 falls below UVTH; deasserts after timeout |
| 4 OV | Active-low overvoltage output | Open-drain; asserts immediately on OV condition; latched if OVLATCH = high |
| 5 SET | Window threshold select | Bias to GND (±5%), VCC (±10%), or VCC/2 (±15%) to configure hysteresis band |
| 6 VCC2 | Secondary monitored supply input | Accepts 0–6.0V; used with external divider to monitor adjustable rail (e.g., 1.2V, 1.5V) |
| 7 GND | Ground reference | Common return for all circuitry; EP (pin 8) must be connected to GND for thermal performance |
| 8 VCC | Main supply & monitored voltage | Powers device and serves as primary 3.3V rail monitor; valid operation from 1.4V to 6.0V |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent voltage monitoring | Simultaneously supervises 3.3V main rail (VCC) and user-adjustable secondary rail (VCC2), eliminating need for two discrete monitors |
| Latched overvoltage output | OVLATCH pin enables persistent fault indication until explicitly cleared-essential for diagnostic logging in automotive ECUs |
| Factory-trimmed + adjustable thresholds | VCC fixed at 3.3V; VCC2 configurable from 0.9V to 3.3V using standard resistor values per Figure 5 |
| 100ms minimum reset timeout | Guarantees sufficient hold time for microprocessor initialization after power recovery, preventing premature release |
| Low 13µA supply current | Enables continuous monitoring in battery-backed systems without significant drain impact |
| AEC-Q100 qualified | Validated for automotive applications per Grade 1 (-40°C to +125°C) requirements |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-voltage window monitoring applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6761TATAD3+T | Identical pinout, package, and electrical specs; differs only in UV/OV output polarity (MAX6761 = active-high UV, active-low OV) | Requires inverted logic handling in host firmware; unsuitable where push-pull active-low UV is mandatory | Select MAX6761TATAD3+T only when system design expects active-high undervoltage signaling |
| TPS3808G33DBVR | Single-supply (3.3V only), no VCC2 input or OVLATCH; 200ms timeout; SOT-23-6 package | Lacks dual-rail capability and fault latching; limited to basic 3.3V monitoring without secondary rail support | Choose TPS3808G33DBVR only for cost-sensitive single-rail applications where latch and VCC2 are unnecessary |
Compared with MAX6761TATAD3+T and TPS3808G33DBVR, the MAX6762TATAD3+T uniquely delivers dual-rail monitoring with latched OV response in a space-constrained TDFN-8 package-critical for automotive and telecom designs requiring fault persistence and secondary rail visibility.

FAQ
What is the primary monitored voltage for MAX6762TATAD3+T?
The MAX6762TATAD3+T primarily monitors VCC at a factory-trimmed 3.3V nominal level. Its secondary input VCC2 supports adjustable monitoring from 0.9V to 3.3V using an external resistor divider referenced to 0.4255V. This dual-monitoring capability enables coordinated supervision of main and auxiliary rails in complex power architectures.
How does the OVLATCH pin function on MAX6762TATAD3+T?
The OVLATCH pin on MAX6762TATAD3+T controls latching behavior of the OV output: when driven high, it latches the OV signal upon any overvoltage event on VCC or VCC2; when driven low, it clears the latch after overvoltage conditions are removed. The latch remains transparent when OVLATCH is tied to GND, allowing immediate OV assertion/clearing without persistence.
What timeout period is implemented in MAX6762TATAD3+T?
The MAX6762TATAD3+T implements a D3-suffix 100ms minimum reset timeout period. After VCC or VCC2 recovers above its undervoltage threshold, the RESET and UV outputs remain asserted for at least 100ms (typical 185ms, max 320ms) to ensure stable microprocessor initialization before release.
Can MAX6762TATAD3+T monitor voltages below 1.0V?
No-MAX6762TATAD3+T requires VCC ≥ 1.4V for full functional operation, though outputs maintain correct logic state down to VCC = 1.0V. Its VCC2 input supports monitoring as low as 0.9V (suffix 'E') when configured with appropriate external resistors, but the device itself cannot operate or monitor below 0.9V nominal due to internal reference constraints.
Is MAX6762TATAD3+T qualified for automotive applications?
Yes-MAX6762TATAD3+T carries AEC-Q100 qualification for automotive use (Grade 1, -40°C to +125°C), verified per stress testing standards for humidity, temperature cycling, and ESD. Its TDFN-8 package with exposed pad meets automotive thermal and reliability requirements for engine control and ADAS subsystems.
