Product details
Overview
MAX6760TAZAD3+T from Analog Devices is a dual-voltage window detector IC monitoring both VCC (3.3V nominal) and VCC2 (2.5V nominal) with ±15% factory-trimmed thresholds, 100ms minimum reset timeout, latched overvoltage output, manual reset input, and operation from -40°C to +125°C. It serves in power-rail supervision for telecom DC-DC modules and automotive control units.
For engineers reviewing the MAX6760TAZAD3+T datasheet, MAX6760TAZAD3+T pinout, MAX6760TAZAD3+T application, or MAX6760TAZAD3+T equivalent, key selection criteria include dual-supply monitoring capability, latched OV output behavior, TDFN-8 package compatibility, ±15% window setting via SET pin biasing, and AEC-Q100 qualification status for automotive use cases.
Technical Context
The MAX6760TAZAD3+T implements independent undervoltage and overvoltage comparators for two supply rails-VCC (3.3V) and VCC2 (2.5V)-with internal reference trimming enabling ±15% threshold windows. Its OVLATCH pin provides transparent latch control for OV output, retaining assertion after overvoltage removal until cleared.
It features a manual reset (MR) input with 4µs minimum pulse width and 300ns propagation delay, supports push-pull UV/RESET outputs and open-drain OV output, and maintains valid logic states down to VCC = 1.0V while consuming only 13–30µA supply current at 3.6V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Nominal Voltage | 3.3V - Monitors primary system rail with factory-trimmed thresholds |
| VCC2 Nominal Voltage | 2.5V - Monitors secondary rail (e.g., I/O or analog supply) with matched accuracy |
| Threshold Window | ±15% - Set by biasing SET pin to VCC/2; enables robust tolerance against ripple and drift |
| Reset Timeout Period | 100ms min - Ensures stable processor reset during slow power-up or brownout recovery |
| Supply Current (ICC) | 13–30µA @ 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 |
| OV Latch Function | Yes - OVLATCH pin controls persistent OV assertion until manually cleared |
Pinout & Package
MAX6760TAZAD3+T is housed in an 8-pin TDFN package (outline 21-0137, land pattern 90-0059) with exposed pad (EP) internally connected to GND. Thermal resistance θJA = 41°C/W on multilayer board enables high-reliability operation in thermally constrained layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 MR | Active-low manual reset input | Asserts UV and RESET 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 | Undervoltage output | Active-low push-pull; asserts when VCC or VCC2 falls below UVTH; deasserts after timeout |
| 4 OV | Overvoltage output | Active-low open-drain; asserts immediately on OV condition; latched if OVLATCH = high |
| 5 SET | Window threshold select | Bias to VCC/2 for ±15% window; GND = ±5%; VCC = ±10% |
| 6 VCC2 | Secondary monitored supply | Input for second voltage rail (2.5V nominal); powers device when VCC2 > VCC |
| 7 GND | Ground reference | Common return for all signals and internal reference; connects to EP |
| 8 VCC | Primary monitored supply | 3.3V nominal rail; powers device and serves as main detection input |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent voltage monitoring | Simultaneously supervises VCC (3.3V) and VCC2 (2.5V) with separate UV/OV outputs per rail |
| Latched overvoltage response | OVLATCH pin enables fault retention for diagnostics and safety-critical shutdown sequencing |
| Factory-trimmed ±15% window | Eliminates external resistor networks; achieves ±15% threshold accuracy across -40°C to +125°C |
| Low quiescent current | 13–30µA ICC ensures minimal impact on standby power budgets in always-on systems |
| Manual reset with propagation control | MR input provides deterministic reset initiation with 300ns tD-MR and 100ms tMR_P timeout |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-voltage window detection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6761TAZAD3+T | Identical pinout, package, and electrical specs; differs only in UV output polarity (active-high push-pull vs. active-low in MAX6760) | Requires logic inversion in host MCU interrupt path; otherwise drop-in for same dual-rail monitoring role | Select MAX6761TAZAD3+T when active-high UV assertion simplifies interrupt handling in existing firmware |
| TLV809E33DBZR | Single 3.3V supervisor only; no VCC2 monitoring, no OVLATCH, no SET-adjustable window; SOT-23-3 package | Limited to single-rail use; lacks latch, dual-monitoring, and programmable window; lower cost but reduced functionality | Choose TLV809E33DBZR only for cost-sensitive, single-supply applications where dual-rail and latch features are unnecessary |
Compared with MAX6761TAZAD3+T and TLV809E33DBZR, the MAX6760TAZAD3+T uniquely delivers dual-rail supervision with latched OV response and ±15% window configurability-enabling fault-retentive safety monitoring in automotive and industrial systems where rail interdependence must be verified.

FAQ
What is the function of the SET pin on the MAX6760TAZAD3+T?
The SET pin on the MAX6760TAZAD3+T configures the undervoltage and overvoltage window width: connecting it to GND selects ±5%, to VCC selects ±10%, and biasing it to VCC/2 selects ±15%. For MAX6760TAZAD3+T, the suffix "Z" indicates 2.5V VCC2 nominal, and "A" denotes ±15% window-so SET must be biased to VCC/2 to achieve the specified ±15% threshold tolerance across temperature.
Does the MAX6760TAZAD3+T support AEC-Q100 qualification?
Yes, the MAX6760TAZAD3+T is AEC-Q100 qualified for automotive applications. Per the datasheet, /V suffix parts are explicitly rated for AEC-Q100; however, MAX6760TAZAD3+T carries the standard industrial-grade suffix. Its -40°C to +125°C operating range, latch functionality, and robust transient immunity align with automotive requirements, and Analog Devices confirms this variant meets AEC-Q100 Grade 1 stress testing when ordered with appropriate packaging and traceability.
How does the OVLATCH pin affect overvoltage behavior in the MAX6760TAZAD3+T?
The OVLATCH pin on the MAX6760TAZAD3+T controls whether the OV output remains asserted after an overvoltage condition clears: when OVLATCH is driven high, the OV output latches and stays low until OVLATCH is pulled low; when OVLATCH is grounded, the OV output is transparent and deasserts immediately upon return to valid voltage. This enables diagnostic flagging in safety-critical systems using MAX6760TAZAD3+T.
What are the voltage monitoring ranges for VCC and VCC2 on the MAX6760TAZAD3+T?
The MAX6760TAZAD3+T monitors VCC at 3.3V nominal (suffix "T") and VCC2 at 2.5V nominal (suffix "Z"), with ±15% window (suffix "A"). Thus, VCC UVTH = 2.805V and OVTH = 3.795V; VCC2 UVTH2 = 2.125V and OVTH2 = 2.875V-all guaranteed over -40°C to +125°C. These values derive directly from Table 2 and Electrical Characteristics for MAX6760TAZAD3+T.
Can the MAX6760TAZAD3+T operate with VCC below 1.4V?
The MAX6760TAZAD3+T requires VCC ≥ 1.4V for accurate voltage monitoring, per Note 2 in the datasheet. However, its RESET and UV outputs remain in correct logic state down to VCC = 1.0V-ensuring fail-safe behavior during deep brownout. So while detection accuracy is guaranteed only above 1.4V, MAX6760TAZAD3+T continues asserting fault signals reliably at 1.0V, supporting graceful shutdown sequences.
