Product details
Overview
MAX6762TALAD3+T from Analog Devices is a dual-voltage window detector IC monitoring both VCC and VCC2 supplies, with factory-trimmed 3.3V/1.8V thresholds, ±15% window select via SET pin, latched overvoltage output, manual reset input, and 100ms minimum reset timeout. It operates from -40°C to +125°C in automotive and industrial power-rail supervision.
For engineers reviewing the MAX6762TALAD3+T datasheet, MAX6762TALAD3+T pinout, MAX6762TALAD3+T application, or MAX6762TALAD3+T equivalent, key selection criteria include dual-supply monitoring capability, latch-enabled OV response, 100ms timeout period, ±15% window tolerance, and TDFN-8 package compatibility with high-temperature embedded systems.
Technical Context
The MAX6762TALAD3+T implements independent undervoltage and overvoltage comparators for two supply rails (VCC = 3.3V nominal, VCC2 = 1.8V nominal), each with programmable ±15% window via SET bias at VCC/2. It features latched OV output controlled by OVLATCH, active-low MR with 26kΩ internal pullup, and guaranteed operation down to VCC = 1.0V while maintaining correct output states.
Its architecture includes separate UV/OV outputs (UV and OV open-drain), internal reference generation, transient-immune threshold detection (300ns immunity), and temperature-stable thresholds across -40°C to +125°C. The D3 suffix confirms 100ms minimum reset timeout, and the TA/LA/RA/ZA/WA/AA suffix family supports adjustable VCC2 monitoring down to 0.9V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Nominal | 3.3V - primary monitored supply voltage with factory-trimmed UVTH/OVTH |
| VCC2 Nominal | 1.8V - secondary monitored supply voltage, internally trimmed for dual-rail supervision |
| Window Tolerance | ±15% - set by biasing SET pin to VCC/2; enables robust margin against rail drift |
| Reset Timeout | 100ms min - ensures stable microprocessor reset after power recovery |
| Supply Current | 13µA typ at 3.6V - ultra-low quiescent current for battery-backed or always-on systems |
| Operating Temp | -40°C to +125°C - qualified for under-hood automotive and industrial control environments |
| OV Latch Function | Enabled - OVLATCH pin controls persistent OV assertion until cleared externally |
Pinout & Package
MAX6762TALAD3+T is housed in an 8-pin TDFN package (package code T833+2, outline 21-0137) with exposed pad (EP) internally connected to GND. Thermal resistance θJA is 41°C/W on multilayer board, enabling high-power-density placement.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 MR | Active-low manual reset input | Asserts UV and OV outputs; internally pulled up to VCC (26kΩ); 4µs min pulse width |
| 2 OVLATCH | Overvoltage latch control | High = latch OV; low = clear latch; high-impedance input requiring external pullup/pulldown |
| 3 UV | Active-low undervoltage output | Open-drain; asserts when VCC or VCC2 falls below UVTH; deasserts after timeout |
| 4 OV | Active-low overvoltage output | Open-drain; asserts when VCC or VCC2 exceeds OVTH; latched if OVLATCH = high |
| 5 SET | Window threshold select | Bias to VCC/2 for ±15% window; GND = ±5%, VCC = ±10% |
| 6 VCC2 | Secondary supply input | Monitored voltage rail (1.8V nominal); powers device if VCC2 > VCC |
| 7 GND | Ground reference | Common return for all analog/digital circuitry and EP connection point |
| 8 VCC | Primary supply input | Main power and primary monitored rail (3.3V nominal); valid down to 1.0V |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent voltage monitoring | Simultaneously supervises 3.3V (VCC) and 1.8V (VCC2) rails with separate UV/OV outputs |
| Latched overvoltage response | OVLATCH pin enables persistent fault indication until system-level intervention clears latch |
| Factory-trimmed thresholds | Eliminates external resistor networks; ±1.5% initial accuracy over temperature for 3.3V/1.8V rails |
| Manual reset with propagation delay | MR input provides hardware-initiated reset with 300ns tD-MR and configurable timeout (D3 = 100ms) |
| Low-voltage operation guarantee | Outputs remain valid and correctly asserted even as VCC drops to 1.0V |
Applications
| Power-Rail Supervision in Automotive ECUs | Industrial PLC I/O Module Power Monitoring |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-supply voltage monitoring applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6761TALAD3+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 MCU GPIO or external inverter for UV path | Select when system design expects active-high undervoltage signaling |
| TLV809E33DBZR | Single 3.3V supervisor only; no VCC2 monitoring, no OV latch, no SET-adjustable window, SOT-23-3 package | Cannot replace dual-rail functionality; suitable only for single-rail backup monitoring | Use only as partial substitute where only primary rail supervision is needed |
Compared with MAX6762TALAD3+T, MAX6761TALAD3+T offers identical dual-rail timing and latching but inverted UV polarity-requiring minimal firmware adjustment-while TLV809E33DBZR lacks VCC2 support, latch, and window adjustability, limiting it to basic single-rail use cases.

FAQ
What voltage rails does the MAX6762TALAD3+T monitor?
The MAX6762TALAD3+T monitors two independent supply rails: VCC at 3.3V nominal and VCC2 at 1.8V nominal. Both rails have factory-trimmed undervoltage and overvoltage thresholds, with ±15% window tolerance selectable via the SET pin biased to VCC/2. This dual-monitoring capability enables comprehensive power integrity checking in systems with multiple voltage domains.
Does the MAX6762TALAD3+T support latched overvoltage detection?
Yes, the MAX6762TALAD3+T supports latched overvoltage detection via the OVLATCH pin. When OVLATCH is driven high, the OV output remains asserted after an overvoltage event until OVLATCH is actively pulled low. This latch function enables persistent fault reporting for diagnostic logging or safe shutdown sequencing without continuous software polling of the OV signal.
What is the reset timeout period for the MAX6762TALAD3+T?
The MAX6762TALAD3+T has a 100ms minimum reset timeout period, indicated by the "D3" suffix in its part number. After VCC or VCC2 recovers above its UV threshold or drops below its OV threshold, the RESET/UV output remains asserted for at least 100ms before deasserting-ensuring stable microprocessor initialization and avoiding premature release during marginal power recovery.
Can the MAX6762TALAD3+T operate with supply voltages below 3.3V?
Yes, the MAX6762TALAD3+T operates with VCC as low as 1.0V while maintaining correct output logic states. Its internal circuitry remains functional down to this level, though the monitored 3.3V rail must be ≥1.4V for accurate threshold comparison. This low-voltage capability supports brownout detection and graceful shutdown in battery-powered or energy-harvesting systems.
What package type is used for the MAX6762TALAD3+T?
The MAX6762TALAD3+T uses an 8-pin TDFN package (outline 21-0137, package code T833+2) with an exposed pad (EP) internally connected to GND. This compact, thermally efficient package delivers θJA = 41°C/W on multilayer boards and supports reflow soldering per JEDEC J-STD-020, making it suitable for high-density automotive and industrial PCB layouts.
