Product details
Overview
MAX6760TATAD0+T from Analog Devices is a dual-voltage window detector IC monitoring both VCC and VCC2 supplies with factory-trimmed thresholds (3.3V/2.5V nominal), ±10% window tolerance, 20μs propagation delay, latched overvoltage output, and manual reset input. It operates from -40°C to +125°C in automotive and industrial power-rail supervision.
For engineers reviewing the MAX6760TATAD0+T datasheet, MAX6760TATAD0+T pinout, MAX6760TATAD0+T application, or MAX6760TATAD0+T equivalent, key selection criteria include dual-supply monitoring capability, latch-enabled OV response, 20μs fast timeout, AEC-Q100-qualified operation, and TDFN-8 package compatibility with high-density PCB layouts.
Technical Context
The MAX6760TATAD0+T implements independent undervoltage and overvoltage comparators for two supply rails-VCC (3.3V nominal) and VCC2 (2.5V nominal)-with internal reference trimming and SET-pin programmable ±10% window. Its OVLATCH input enables persistent OV fault signaling until cleared externally.
It features a 20μs propagation delay (D0 suffix), push-pull UV/RESET outputs, open-drain OV output, and MR input with 26kΩ internal pullup. The device asserts outputs when either monitored rail falls below UVTH or exceeds OVTH, with guaranteed functionality down to VCC = 1.0V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Nominal | 3.3V - primary monitored supply voltage; sets internal UV/OV thresholds |
| VCC2 Nominal | 2.5V - secondary monitored supply; supports dual-rail supervision |
| Window Tolerance | ±10% - selected via SET = VCC; defines hysteresis band around nominal thresholds |
| Timeout Period | 20μs typ - fast reset assertion/deassertion timing for real-time fault response |
| Supply Current | 13–30µA at 3.6V - ultra-low quiescent current enabling battery-backed or energy-sensitive systems |
| Operating Temp | -40°C to +125°C - qualified for under-hood automotive and industrial environments |
| Output Types | UV/RESET: push-pull; OV: open-drain - enables flexible interface with µP reset logic and external pull-up requirements |
Pinout & Package
MAX6760TATAD0+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 = 41°C/W on multilayer board enables reliable operation at full temperature range without heatsinking.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 MR | Active-low manual reset input | Asserts UV/RESET outputs when pulled low; 26kΩ internal pullup to VCC ensures default high state |
| 2 OVLATCH | Overvoltage latch control | High = latch OV output; low = clear latch; high-impedance input requires external pullup/pulldown |
| 3 UV | Undervoltage output | Push-pull active-low output; asserts when VCC or VCC2 falls below respective UVTH |
| 4 OV | Overvoltage output | Open-drain active-low output; asserts immediately on OV condition; latched if OVLATCH = high |
| 5 SET | Window threshold select | Connected to VCC for ±10% window; GND = ±5%; biased at VCC/2 = ±15% |
| 6 VCC2 | Secondary supply input | Monitored voltage rail (2.5V nominal); powers internal circuitry only when VCC2 > VCC |
| 7 GND | Ground reference | Common return path for all analog and digital functions; EP must be connected to GND |
| 8 VCC | Primary supply input | Main power and primary monitored rail (3.3V nominal); valid down to 1.0V for output integrity |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent voltage monitoring | Simultaneously supervises VCC (3.3V) and VCC2 (2.5V) with separate UV/OV comparators and thresholds |
| Latched overvoltage output | OVLATCH pin enables persistent OV fault flagging until system-level intervention clears the latch |
| Factory-trimmed ±10% window | Eliminates external resistor networks; SET = VCC configures precise 3.3V/2.5V detection with ±10% tolerance |
| 20μs fast-response timeout | Enables immediate microprocessor reset or fault shutdown without delay-induced system instability |
| AEC-Q100 qualified | Validated for automotive applications including engine control units and ADAS power domains |
| Low 10µA supply current | Supports always-on monitoring in battery-powered telematics and ECU sleep modes |
Applications
| Automotive Engine Control Unit (ECU) | Industrial PLC Power Sequencing |
|---|---|
Use Scenario: Monitoring 3.3V microcontroller core supply and 2.5V sensor interface rail in engine management systems.

Use Value: Ensures deterministic MCU reset behavior during cold-start voltage sag and alternator overvoltage spikes up to 16V. | Use Scenario: Coordinating startup/shutdown sequencing of 3.3V logic and 2.5V analog subsystems in programmable logic controllers. IC Role / Device Role / Timing Role: Independent UV/OV detection per rail with 20μs response guarantees synchronized power-good signaling across FPGA, ADC, and I/O banks. Use Value: Prevents metastability and configuration corruption by enforcing strict voltage sequencing before firmware execution begins. |
| Telecom Base Station DC-DC Modules | Rail-Specific Server Power Management |
Use Scenario: Supervising isolated 3.3V control and 2.5V transceiver supplies in 48V-to-point-of-load converters. IC Role / Device Role / Timing Role: Dual-supply monitor with open-drain OV output interfaces directly to baseband processor interrupt lines; MR allows remote reset initiation. Use Value: Enables rapid fault isolation and graceful degradation when one DC-DC stage fails while maintaining uptime on unaffected subsystems. | Use Scenario: Detecting brownout conditions on 3.3V motherboard management controller (BMC) and 2.5V memory buffer rails in data center servers. IC Role / Device Role / Timing Role: Push-pull UV output drives BMC reset pin directly; latched OV output triggers hardware watchdog escalation on sustained overvoltage. Use Value: Reduces mean time to recovery (MTTR) by eliminating software polling delays and enabling autonomous hardware-level fault containment. |
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 |
|---|---|---|---|
| MAX6761TATAD0+T | Identical pinout and electrical specs; differs only in UV output polarity (active-high push-pull vs. MAX6760's active-low) | Requires inverted reset logic handling in µP interface; otherwise drop-in compatible for same voltage pairs | Select when host microcontroller expects active-high reset assertion |
| TPS3808G33DBVR | Single-supply only (3.3V), no VCC2 monitoring; fixed ±3% window; 200ms min timeout (no D0 option) | Cannot supervise dual rails; lacks OVLATCH and MR functionality; unsuitable for systems requiring latch persistence | Use only for cost-sensitive single-rail applications where fast 20μs timeout is not required |
Compared with MAX6761TATAD0+T, the MAX6760TATAD0+T provides native active-low UV output for direct µP reset pin compatibility; versus TPS3808G33DBVR, it delivers true dual-rail supervision, latch control, and sub-millisecond response-critical for automotive safety-critical power domains.

FAQ
What is the function of the OVLATCH pin on the MAX6760TATAD0+T?
The OVLATCH pin on the MAX6760TATAD0+T controls latching behavior of the overvoltage output. When driven high, it latches the OV output in asserted state until cleared by pulling OVLATCH low after overvoltage conditions resolve. When tied to GND, the OV output operates transparently-deasserting immediately upon return to safe voltage. This enables fail-safe fault logging in automotive ECUs.
Does the MAX6760TATAD0+T monitor both VCC and VCC2 simultaneously?
Yes, the MAX6760TATAD0+T monitors VCC (3.3V nominal) and VCC2 (2.5V nominal) simultaneously using independent comparator circuits. An undervoltage or overvoltage condition on either rail asserts the corresponding UV or OV output. Both rails are supervised with identical ±10% window tolerance set by the SET pin connected to VCC.
What does the 'D0' suffix indicate in MAX6760TATAD0+T?
The 'D0' suffix in MAX6760TATAD0+T specifies a 20μs typical timeout period for the RESET and UV outputs. This fast response enables immediate microprocessor reset assertion upon supply fault detection-critical for real-time systems like automotive ADAS where latency must be minimized. The alternative D3 suffix provides 100ms minimum timeout.
Can the MAX6760TATAD0+T operate with VCC below 3.3V?
Yes, the MAX6760TATAD0+T operates with VCC as low as 1.0V while maintaining correct output logic states. Its internal reference and comparators remain functional down to this level, though the specified 3.3V nominal threshold applies only when VCC ≥ 1.4V. Below 1.4V, outputs hold last valid state-ensuring robustness during brownout recovery.
Is the MAX6760TATAD0+T AEC-Q100 qualified?
Yes, the MAX6760TATAD0+T is AEC-Q100 qualified for automotive applications. It meets Grade 1 temperature requirements (-40°C to +125°C) and undergoes stress testing for reliability in harsh environments such as engine compartments and transmission control modules.
