Product details
Overview
MAX6762TATAD0+T from Analog Devices is a dual-voltage window detector IC that monitors both VCC (3.3V nominal) and VCC2 (adjustable down to 0.9V) for undervoltage/overvoltage conditions, with ±10% factory-set window tolerance, 20μs typical reset timeout, latched overvoltage output, manual reset input, and operation from -40°C to +125°C. It serves as a system-level power supervisor in telecom DC-DC modules.
For engineers reviewing the MAX6762TATAD0+T datasheet, MAX6762TATAD0+T pinout, MAX6762TATAD0+T application, or MAX6762TATAD0+T equivalent, key selection criteria include dual-supply monitoring capability, latched OV output behavior, TDFN-8 package footprint, ±10% threshold accuracy across temperature, and compatibility with automotive-grade thermal and reliability requirements.
Technical Context
The MAX6762TATAD0+T implements independent UV/OV comparators for two supplies: VCC (fixed 3.3V nominal) and VCC2 (externally adjustable via resistor divider to 0.9–3.3V), each with ±10% window set by SET = VCC. It features a transparent OVLATCH input enabling persistent OV assertion until cleared, and a manual reset (MR) with 4μs minimum pulse width and internal 26kΩ pullup.
Its timing architecture delivers 20μs propagation delay on UV/OV assertion and no timeout on OV deassertion (latched mode), while RESET/UV outputs deassert after 20μs once supply recovers. The device maintains valid output states down to VCC = 1.0V and draws only 13–30μA supply current at 3.6V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Nominal Voltage | 3.3V - fixed internal reference for primary supply monitoring |
| VCC2 Monitoring Range | 0.9V to 3.3V - externally adjustable via resistor divider, enabling flexible secondary rail supervision |
| Window Tolerance | ±10% - set by connecting SET pin to VCC; provides defined margin against supply ripple and drift |
| Reset Timeout | 20μs (typ) - fast recovery timing option (D0 suffix), suitable for high-speed microprocessor reset coordination |
| Supply Current | 13–30μA at 3.6V - enables always-on supervision in battery-backed or low-power systems |
| Operating Temperature | -40°C to +125°C - qualified for under-hood automotive and industrial embedded environments |
| OVLATCH Function | Latched overvoltage output - holds OV low until explicitly cleared, preventing transient-induced false resets |
Pinout & Package
MAX6762TATAD0+T is housed in an 8-pin TDFN package (package code T833+2, outline 21-0137) with exposed pad connected to GND. This thermally enhanced package supports high-reliability operation in compact, high-density PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - MR | Active-low manual reset input | Asserts UV and RESET outputs when pulled low; internal 26kΩ pullup to VCC ensures default high state |
| 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 low when VCC or VCC2 falls below UVTH; deasserts after 20μs recovery |
| 4 - OV | Active-low overvoltage output | Open-drain; asserts low when VCC or VCC2 exceeds OVTH; remains latched until OVLATCH is cleared |
| 5 - SET | Window threshold select | Connected to VCC for ±10% window; biasing determines hysteresis width for noise immunity |
| 6 - VCC2 | Secondary monitored supply input | Accepts 0–6.0V; used with external divider to set adjustable 0.9–3.3V monitoring point |
| 7 - GND | Ground reference | Common return for all analog and digital circuitry; EP (pin 8) must be connected to GND for thermal performance |
| 8 - VCC | Primary supply input & power rail | 3.3V nominal monitored voltage and device power source; valid operation down to 1.0V |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent voltage monitoring | Simultaneously supervises VCC (3.3V fixed) and VCC2 (0.9–3.3V adjustable), eliminating need for two discrete supervisors |
| Latched overvoltage output | OVLATCH pin enables fail-safe OV reporting that persists through supply transients, critical for fault logging and safety shutdown |
| Factory-trimmed ±10% window | Reduces BOM count and layout complexity vs. resistor-programmable alternatives; guarantees accuracy over full temperature range |
| 20μs fast timeout option | Enables rapid system recovery after brownout events without compromising noise immunity or stability |
| Low 13–30μA quiescent current | Supports permanent connection to always-on rails in automotive body control modules and IoT edge nodes |

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 |
|---|---|---|---|
| MAX6761TATAD0+T | Identical pinout, package, and electrical specs; differs only in UV output polarity (active-high push-pull vs. active-low) | Requires inverted logic handling in host firmware; otherwise drop-in compatible for same voltage rails and timing | Select when system requires active-high UV signal to avoid external inverter |
| TLV809E33DBZR | Single 3.3V supervisor only; no VCC2 monitoring, no OVLATCH, no manual reset, SOT-23-3 package | Limited to basic single-rail reset generation; lacks dual-monitoring, latch, and adjustability needed for complex systems | Use only for cost-sensitive, single-supply applications where dual-rail supervision is unnecessary |

FAQ
What is the exact VCC2 voltage range supported by the MAX6762TATAD0+T?
The MAX6762TATAD0+T supports VCC2 monitoring from 0.9V to 3.3V using an external resistor divider that sets the VCC2 pin to 0.4255V. This allows precise adjustment of the secondary supply threshold while maintaining ±10% window accuracy across temperature. The device does not monitor VCC2 directly above 3.3V or below 0.9V per its specified operating range.
How does the OVLATCH function behave during a VCC2 overvoltage event?
When VCC2 exceeds its overvoltage threshold, the MAX6762TATAD0+T asserts the OV output low. If OVLATCH is driven high, this OV state remains latched even after VCC2 returns to normal-only driving OVLATCH low clears it. This behavior applies identically to VCC overvoltage events, ensuring fault persistence regardless of which supply triggers the condition.
Can the MAX6762TATAD0+T operate with VCC below 3.3V?
Yes, the MAX6762TATAD0+T operates with VCC from 1.0V to 6.0V. Its internal reference and comparators remain functional down to 1.0V, and outputs retain correct logic states. However, the nominal 3.3V VCC threshold is factory-trimmed and fixed-reducing VCC below 3.3V does not shift the UV/OV trip points; it only affects the supply powering the IC itself.
What is the purpose of the SET pin, and how is it configured for ±10% window tolerance?
The SET pin selects the window tolerance for both VCC and VCC2 thresholds. For ±10%, SET must be connected directly to VCC. This configures internal comparator hysteresis to provide noise immunity against supply ripple up to 330mV on a 3.3V rail. Connecting SET to GND or biasing at VCC/2 selects ±5% or ±15%, respectively.
Is the MAX6762TATAD0+T AEC-Q100 qualified?
No, the MAX6762TATAD0+T is not AEC-Q100 qualified. Only /V-suffixed variants (e.g., MAX6762TATAD0/V+) in the same family meet AEC-Q100 Grade 1 (-40°C to +125°C) requirements. The MAX6762TATAD0+T shares the same operating temperature range but lacks formal automotive qualification documentation and stress testing certification.
