Product details
Overview
MAX6760TALAD3 from Maxim Integrated is a dual-voltage window detector IC that monitors both VCC (5V nominal) and VCC2 (3.3V nominal) for undervoltage/overvoltage conditions, with independent UV/OV open-drain outputs, 100ms minimum reset timeout, latched OV output, manual reset input, and ±5% threshold window. It operates across -40°C to +125°C and supports automotive-grade power-rail supervision in microprocessor-based systems.
For engineers reviewing the MAX6760TALAD3 datasheet, MAX6760TALAD3 pinout, MAX6760TALAD3 application, or MAX6760TALAD3 equivalent, this device is selected for dual-rail monitoring where latch-hold on overvoltage fault, low 13µA supply current, and guaranteed output validity down to VCC = 1.0V are critical design requirements.
Technical Context
The MAX6760TALAD3 implements two independent voltage comparators-one for VCC (5V nominal) and one for VCC2 (3.3V nominal)-each with factory-trimmed thresholds and shared SET pin control of window tolerance (±5% in this variant). Its latched OV output remains asserted until cleared via OVLATCH, enabling fault persistence in safety-critical power sequencing.
It features a manual reset input (MR) with internal 26kΩ pullup, 100ms minimum timeout delay (D3 option), and operates with VCC as both supply and monitored rail for VCC path while VCC2 serves as second monitored rail. Output logic states are valid even when VCC drops to 1.0V, supporting brownout detection during power collapse.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Nominal Threshold | 5.0V (factory-trimmed; OVTH = 5.25–5.75V, UVTH = 4.50–4.75V at TA = -40°C to +125°C) |
| VCC2 Nominal Threshold | 3.3V (factory-trimmed; OVTH2 = 2.97–3.135V, UVTH2 = 2.97–3.135V at TA = -40°C to +125°C) |
| Threshold Window | ±5% (SET = GND; enables tight tolerance for stable 5V/3.3V rail validation) |
| Reset Timeout | 100ms minimum (D3 option; ensures reliable µP reset hold time after power recovery) |
| Supply Current | 13µA typical at VCC = 3.6V (enables always-on supervision in battery-backed systems) |
| Operating Temp | -40°C to +125°C (supports under-hood automotive and industrial embedded environments) |
| Output Type | Open-drain UV and OV (allows wired-OR logic, level translation, and flexible pullup selection) |
Pinout & Package
MAX6760TALAD3 is housed in an 8-pin TDFN-EP package (3mm × 3mm, 0.75mm height) with exposed pad connected to GND for thermal and EMI performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VCC | Primary power supply input and first monitored voltage rail (5V nominal) |
| 2 | GND | Ground reference for all internal circuitry and outputs |
| 3 | OVLATCH | Active-high latch control: high = hold OV assertion, low = clear latch after fault removal |
| 4 | VCC2 | Second monitored voltage rail input (3.3V nominal); also powers device if VCC2 > VCC |
| 5 | UV | Active-low open-drain undervoltage output; asserts when VCC or VCC2 falls below UVTH |
| 6 | OV | Active-low open-drain overvoltage output; asserts when VCC or VCC2 exceeds OVTH; latched via OVLATCH |
| 7 | MR | Active-low manual reset input; internally pulled up to VCC (26kΩ); initiates UV/OV assertion on falling edge |
| 8 | SET | Window select input: GND = ±5%, VCC = ±10%, VCC/2 = ±15%; configures hysteresis for both rails |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent rail monitoring | Simultaneous supervision of VCC (5V) and VCC2 (3.3V) with separate UV/OV outputs enables robust multi-supply system validation |
| Latched overvoltage output | OVLATCH pin allows persistent fault indication until explicitly cleared-critical for fail-safe shutdown sequencing |
| 100ms minimum reset timeout | Guaranteed D3 timing ensures µP reset pulse meets JEDEC JESD76 and Intel VRD specifications |
| Low 13µA supply current | Enables continuous supervision in energy-constrained applications such as automotive body controllers and IoT edge nodes |
| Valid outputs down to VCC = 1.0V | Ensures correct reset/UV state during deep brownout, supporting graceful system shutdown before complete power loss |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-rail voltage monitoring applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6761TALAD3 | Identical pinout, specs, and function; differs only in output configuration-push-pull UV instead of open-drain | Requires no external pullup; less flexible for wired-OR bus sharing but lower BOM cost | Select when UV signal drives dedicated µP input without shared bus constraints |
| TLV809E50DBZR | Single 5V supervisor only; no VCC2 monitoring, no OV latch, no SET-adjustable window; SOT23-3 package | Cannot replace dual-rail functionality; suitable only for simplified single-rail backup monitoring | Use only if system has separate 3.3V monitor or does not require latched OV behavior |
Compared with MAX6761TALAD3, the MAX6760TALAD3 offers open-drain UV for bus arbitration and compatibility with legacy reset architectures; versus TLV809E50DBZR, it delivers full dual-rail supervision with latch persistence-making it irreplaceable in safety-critical multi-supply systems.

FAQ
What is the function of the SET pin on the MAX6760TALAD3?
The SET pin on the MAX6760TALAD3 selects the voltage threshold window tolerance: grounded for ±5%, tied to VCC for ±10%, or biased to VCC/2 for ±15%. For MAX6760TALAD3, SET = GND configures the ±5% window used to supervise 5V and 3.3V rails with tight accuracy. This setting directly determines OVTH and UVTH hysteresis margins per the datasheet's electrical characteristics tables.
Does the MAX6760TALAD3 support operation when VCC drops below 1.4V?
Yes-the MAX6760TALAD3 guarantees correct output logic states (UV/OV asserted/deasserted) for VCC down to 1.0V, though voltage monitoring functionality requires VCC ≥ 1.4V per datasheet Note 2. This means MAX6760TALAD3 maintains valid reset signaling during deep brownout events, enabling controlled system shutdown even as supply collapses toward 1.0V.
How does the OVLATCH pin affect the OV output behavior of the MAX6760TALAD3?
The OVLATCH pin on the MAX6760TALAD3 controls latching of the OV output: driving OVLATCH high holds the OV signal asserted after an overvoltage event, even if VCC/VCC2 returns to normal; driving OVLATCH low clears the latch once fault conditions are removed. When OVLATCH is grounded, the OV output operates transparently (non-latched). This behavior is exclusive to MAX6760/MAX6761/MAX6762 variants and is confirmed in the MAX6760TALAD3 functional diagram and pin description.
What are the absolute maximum ratings for VCC and VCC2 on the MAX6760TALAD3?
The MAX6760TALAD3 has absolute maximum ratings of -0.3V to +6.5V for both VCC and VCC2 pins (with respect to GND), as specified in the Absolute Maximum Ratings table. Exceeding these limits may cause permanent damage. Normal operating range is 1.4V to 6.0V for VCC and 0V to 6.0V for VCC2, with full functionality guaranteed across -40°C to +125°C ambient temperature.
Is the MAX6760TALAD3 pin-compatible with other devices in the MAX6760–MAX6762 series?
Yes-MAX6760TALAD3 shares identical 8-pin TDFN-EP pinout and footprint with MAX6761TALAD3 and MAX6762TALAD3, differing only in UV output type (open-drain vs. push-pull vs. open-drain) and VCC2 threshold suffix. All three support same PCB layout, enabling drop-in substitution where output drive requirements align. Pin compatibility is confirmed in the Pin Configurations section and Ordering Information table.
