Product details
Overview
MAX6762TARAD0 from Maxim Integrated is a dual-voltage window detector IC that monitors both VCC (3.3V nominal) and VCC2 (1.5V nominal) supply rails for undervoltage/overvoltage conditions, featuring independent UV/OV open-drain outputs, 100ms minimum reset timeout, ±10% window tolerance (SET = VCC), latched overvoltage output, and manual reset input - used in microprocessor power supervision for telecom and industrial embedded systems.
For engineers reviewing the MAX6762TARAD0 datasheet, MAX6762TARAD0 pinout, MAX6762TARAD0 application, or MAX6762TARAD0 equivalent, key selection criteria include dual-rail monitoring capability, latched OV output behavior, TDFN-8 package compatibility, -40°C to +125°C operation, and factory-trimmed thresholds with ±10% window selectability.
Technical Context
The MAX6762TARAD0 implements two independent voltage comparators with internal precision references, each configured for fixed-threshold window detection on VCC (3.3V) and VCC2 (1.5V). Its latched OV output remains asserted until cleared via OVLATCH, while UV and OV outputs are open-drain with guaranteed logic states down to VCC ≥ 1.0V.
It uses a single SET pin to configure window width (±5%/±10%/±15%) across both monitored rails, supports manual reset with 26kΩ internal pull-up, and delivers 100ms minimum timeout on RESET/UV assertion after VCC/VCC2 recovery - all operating at 10µA typical supply current over full temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Nominal Threshold | 3.3V ±10% (factory-trimmed, SET = VCC) |
| VCC2 Nominal Threshold | 1.5V ±10% (factory-trimmed, SET = VCC) |
| Reset Timeout Period | 100ms minimum (D3 option) - ensures stable MCU boot after brownout recovery |
| Supply Current (ICC) | 13µA typical at 3.6V - enables always-on monitoring in battery-backed systems |
| Operating Temperature | -40°C to +125°C - qualified for automotive under-hood and industrial control environments |
| Output Type | Open-drain UV and OV; push-pull RESET - supports flexible level-shifting and wired-OR configurations |
| Manual Reset Input | Active-low with 26kΩ internal pull-up - eliminates external resistor for basic reset button interface |
Pinout & Package
MAX6762TARAD0 is housed in an 8-pin TDFN package (3mm × 3mm, 0.75mm height) with exposed pad (EP) internally connected to GND for thermal and electrical performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VCC | Main power supply input and first monitored rail (3.3V nominal) |
| 2 | GND | Ground reference for all internal circuitry and outputs |
| 3 | OVLATCH | High-impedance latch control: high = latch OV, low = clear latch |
| 4 | VCC2 | Second monitored rail input (1.5V nominal); powers device when VCC2 > VCC |
| 5 | MR | Active-low manual reset input with internal 26kΩ pull-up to VCC |
| 6 | UV | Open-drain undervoltage output - asserts low when VCC or VCC2 falls below UVTH |
| 7 | OV | Open-drain overvoltage output - latched low on OV condition until OVLATCH cleared |
| 8 | SET | Window select input: tied to VCC for ±10% threshold tolerance |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent voltage monitoring | Simultaneously supervises 3.3V core and 1.5V I/O rails with separate UV/OV flags - eliminates need for two discrete supervisors |
| Latched overvoltage output | OVLATCH pin enables persistent fault indication until system intervention - critical for safety-critical power sequencing |
| Factory-trimmed ±10% window | SET = VCC configures precise 3.3V/1.5V detection windows without external resistors - reduces BOM count and layout area |
| 100ms minimum reset timeout | Guarantees sufficient hold-off time for complete processor initialization after power recovery - prevents premature release |
| Low 10µA supply current | Enables continuous monitoring in energy-constrained applications like remote sensors and backup power circuits |
| Extended temperature operation | Valid functionality from -40°C to +125°C - meets AEC-Q100 Grade 0 requirements for automotive ECUs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-voltage supervisor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6761TARAD0 | Identical pinout and electrical specs; differs only in UV output polarity (active-high push-pull vs. MAX6762's active-low open-drain) | Requires level-shifting or logic inversion if downstream logic expects active-low UV signal | Select MAX6761TARAD0 only when active-high UV simplifies interface with specific MCU GPIOs |
| TPS3808G33DBVR | Single-supply (3.3V only), no VCC2 input or latched OV; 200ms timeout; SOT-23-6 package | Cannot monitor dual rails or provide latched fault indication - unsuitable for systems requiring independent 1.5V supervision | Choose only for cost-sensitive single-rail designs where latch function is unnecessary |
Compared with MAX6761TARAD0 and TPS3808G33DBVR, the MAX6762TARAD0 uniquely delivers dual-rail monitoring with latched OV in a space-efficient TDFN-8 package, enabling compact, fail-safe power supervision where coordinated fault response across multiple voltage domains is required.

FAQ
What voltage rails does the MAX6762TARAD0 monitor?
The MAX6762TARAD0 monitors two independent supply rails: VCC at 3.3V nominal and VCC2 at 1.5V nominal. Both thresholds are factory-trimmed with ±10% window tolerance (configured by tying SET to VCC). It asserts UV when either rail falls below its undervoltage threshold and OV when either exceeds its overvoltage threshold - making MAX6762TARAD0 ideal for multi-rail microprocessor systems.
Does the MAX6762TARAD0 support latched overvoltage detection?
Yes, the MAX6762TARAD0 includes a dedicated OVLATCH input that enables latched overvoltage behavior. When OVLATCH is driven high, the OV output remains asserted even after the overvoltage condition clears, providing persistent fault indication until explicitly cleared by driving OVLATCH low. This feature is unique to MAX6760/MAX6761/MAX6762 variants and is fully implemented in MAX6762TARAD0.
What is the reset timeout period for MAX6762TARAD0?
The MAX6762TARAD0 has a D3-suffixed timeout option, specifying a minimum reset timeout period of 100ms. After VCC or VCC2 recovers above its UV threshold or drops below its OV threshold, the RESET output remains asserted for at least 100ms before deasserting - ensuring reliable microprocessor initialization. Typical and maximum values are 185ms and 320ms respectively, per datasheet specifications.
What package type is used for MAX6762TARAD0?
The MAX6762TARAD0 is packaged in an 8-pin TDFN (Thin Dual Flat No-lead) case measuring 3mm × 3mm with 0.75mm height and an exposed pad (EP) internally connected to GND. This thermally enhanced package supports high-density PCB layouts and meets JEDEC moisture sensitivity level 1 (MSL-1) requirements for standard assembly processes.
Can MAX6762TARAD0 operate with supply voltages below 1.5V?
Yes, the MAX6762TARAD0 guarantees correct output logic states (RESET, UV, OV) for VCC down to 1.0V, though voltage monitoring functionality requires VCC ≥ 1.4V. Its ultra-low 10µA typical supply current and operation down to 1.0V enable use in brownout scenarios and battery-backed systems where other supervisors would fail - a key design advantage of MAX6762TARAD0.
