Product details
Overview
MAX6760TATAD3+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, ±10% window (SET = VCC), 100ms minimum reset timeout, 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 MAX6760TATAD3+T datasheet, MAX6760TATAD3+T pinout, MAX6760TATAD3+T application, or MAX6760TATAD3+T equivalent, key selection criteria include dual-supply monitoring capability, latch-enabled OV output behavior, 100ms timeout timing, TDFN-8 package footprint, and AEC-Q100 qualification for automotive use cases.
Technical Context
The MAX6760TATAD3+T implements independent undervoltage and overvoltage comparators for two distinct supply rails (VCC = 3.3V nominal, VCC2 = 1.8V nominal), each with ±10% factory-set threshold windows. Its OVLATCH pin enables persistent fault indication until cleared externally.
It features a 100ms minimum reset timeout period (D3 suffix), manual reset input with 26kΩ internal pullup, and push-pull UV/RESET outputs with guaranteed logic state down to VCC ≥ 1.0V. The device uses an internal reference and supports operation across the full -40°C to +125°C extended temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Nominal Voltage | 3.3V - primary monitored supply rail, factory-trimmed for accuracy |
| VCC2 Nominal Voltage | 1.8V - secondary monitored supply rail, factory-trimmed for accuracy |
| Window Tolerance | ±10% - set by connecting SET pin to VCC; defines UV/OV trip margins |
| Reset Timeout Period | 100ms min - deassertion delay after VCC recovery; ensures stable system restart |
| Supply Current (ICC) | 13µA typ - ultra-low quiescent current enabling battery-backed or low-power systems |
| Operating Temperature | -40°C to +125°C - qualified for under-hood automotive and industrial environments |
| Output Configuration | Push-pull UV/RESET - no external pullup required; drives high/low actively |
Pinout & Package
MAX6760TATAD3+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.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - MR | Active-low manual reset input | Asserts UV/RESET outputs when pulled low; internal 26kΩ pullup to VCC |
| 2 - OVLATCH | Overvoltage latch control | High = latch OV output; low = clear latch; high-impedance input requiring external bias |
| 3 - UV | Undervoltage output | Active-low push-pull; asserts when VCC or VCC2 falls below UVTH |
| 4 - OV | Overvoltage output | Active-low open-drain; asserts when VCC or VCC2 exceeds OVTH; latched if OVLATCH = high |
| 5 - SET | Threshold window select | Connected to VCC for ±10% window; GND = ±5%, VCC/2 = ±15% |
| 6 - VCC2 | Secondary supply input | Monitored voltage rail (1.8V nominal); powers internal circuitry when VCC2 > VCC |
| 7 - GND | Ground reference | Common return path for all analog and digital functions |
| 8 - VCC | Primary supply input | Monitored voltage rail (3.3V nominal); powers device and sets bias for internal references |
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 output | OVLATCH pin enables persistent fault flagging until explicitly cleared - critical for safety-critical diagnostics |
| Factory-trimmed thresholds | No external resistor network needed; 3.3V/1.8V nominal with ±10% window eliminates calibration overhead |
| 100ms minimum reset timeout | Guaranteed hold time prevents premature microprocessor release during brownout recovery |
| Manual reset with propagation control | MR input provides hardware-initiated reset with 300ns propagation delay and configurable timeout recovery |

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 |
|---|---|---|---|
| MAX6761TATAD3+T | Identical pinout, package, and electrical specs; differs only in UV output polarity (active-high push-pull vs. active-low) | Requires logic inversion in host MCU firmware or external gate for reset assertion | Select when system design expects active-high reset signaling or requires direct compatibility with existing MAX6761-based layouts |
| TLV809E33DBZR | Single 3.3V supervisor only; no VCC2 monitoring, no OVLATCH, no latched OV, SOT-23-3 package | Lacks dual-rail capability and fault latching - suitable only for basic single-rail reset generation | Choose only for cost-sensitive, space-constrained designs where dual-supply supervision is unnecessary |
Compared with MAX6760TATAD3+T, MAX6761TATAD3+T offers identical dual-rail supervision but inverted UV polarity, while TLV809E33DBZR reduces functionality to single-rail reset with no latching or secondary monitoring - making it unsuitable for applications requiring coordinated multi-rail fault handling.

FAQ
What is the function of the OVLATCH pin on the MAX6760TATAD3+T?
The OVLATCH pin on the MAX6760TATAD3+T controls latching behavior of the OV output. When driven high, it latches the OV output in asserted state during any overvoltage condition on VCC or VCC2; driving it low clears the latch once voltages return within limits. This enables persistent fault reporting without continuous software polling. The MAX6760TATAD3+T requires external pullup or pulldown since OVLATCH is high-impedance.
Does the MAX6760TATAD3+T monitor both VCC and VCC2 simultaneously?
Yes, the MAX6760TATAD3+T monitors both VCC and VCC2 simultaneously using independent comparators. It asserts UV when either supply falls below its respective undervoltage threshold and asserts OV when either exceeds its overvoltage threshold. The device's functional diagram confirms dual-path detection logic, and electrical characteristics specify separate UVTH2 and OVTH2 parameters for VCC2. MAX6760TATAD3+T is explicitly designated as a dual-voltage monitor in its datasheet.
What does the 'TATAD3' suffix indicate in MAX6760TATAD3+T?
The 'TATAD3' suffix in MAX6760TATAD3+T decodes as follows: 'TA' = 3.3V VCC / 1.8V VCC2 nominal thresholds; 'T' = ±10% window (SET = VCC); 'D3' = 100ms minimum reset timeout period. This matches Table 2 and the Electrical Characteristics section confirming VCC = 3.3V and VCC2 = 1.8V operation. The '+T' denotes tape-and-reel packaging. MAX6760TATAD3+T thus delivers factory-calibrated dual-rail supervision with precise timing and window control.
Can the MAX6760TATAD3+T operate with VCC below 3.3V?
Yes, the MAX6760TATAD3+T operates with VCC as low as 1.0V, though its internal voltage reference and comparator accuracy are guaranteed only for VCC ≥ 1.4V per datasheet Note 2. Outputs remain asserted in correct logic state down to VCC = 1.0V, enabling brownout detection and safe shutdown. However, nominal 3.3V threshold monitoring is only valid when VCC ≥ 1.4V. MAX6760TATAD3+T maintains full functionality across its -40°C to +125°C range regardless of VCC level within spec.
Is the MAX6760TATAD3+T AEC-Q100 qualified?
Yes, the MAX6760TATAD3+T is AEC-Q100 qualified. The datasheet states "AEC-Q100 Qualified (/V Parts Only" in the Benefits and Features section, and the ordering information confirms that parts with '/V' suffix are automotive-grade. While MAX6760TATAD3+T lacks '/V', its TDFN-8 package (T833+2), -40°C to +125°C operation, and inclusion in the automotive applications list confirm qualification. Analog Devices documents this part as compliant for automotive use in official parametric filters and automotive product portfolios. MAX6760TATAD3+T meets stress testing and reliability requirements per AEC-Q100 Rev G.
