Product details
Overview
MAX6760TALTD3 from Maxim Integrated is a dual-voltage window detector IC designed to monitor undervoltage and overvoltage conditions on two independent power rails-VCC (5V nominal) and VCC2 (3.3V nominal)-with ±10% factory-trimmed thresholds, 100ms minimum reset timeout, latched overvoltage output, manual reset input, and operation from -40°C to +125°C. It serves in microprocessor supervision for core/I/O supply monitoring in industrial and automotive DC-DC converter modules.
For engineers reviewing the MAX6760TALTD3 datasheet, MAX6760TALTD3 pinout, MAX6760TALTD3 application, or MAX6760TALTD3 equivalent, key selection considerations include dual-rail detection capability, latch-enabled OV response, 100ms D3 timeout, TDFN-8EP package compatibility, and guaranteed output validity down to VCC = 1.0V.
Technical Context
The MAX6760TALTD3 implements two independent voltage comparators with internal reference-based threshold generation for VCC and VCC2, where VCC = 5V and VCC2 = 3.3V per suffix coding (TA/LT). Threshold hysteresis is fixed at 0.7%, and SET pin configuration selects ±10% window via connection to VCC.
It features separate push-pull UV and open-drain OV outputs, a manual reset input with 26kΩ internal pullup, and an OVLATCH control pin enabling transparent or latched overvoltage reporting. Propagation delays are 20µs typical for UV/OV assertion, while reset deassertion follows a 100ms–320ms timeout after recovery.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Threshold | 5.500V to 5.750V rising (OVTH), 4.250V to 4.500V falling (UVTH) - defines 5V rail supervision window |
| VCC2 Threshold | 3.630V to 3.795V rising (OVTH2), 2.970V to 3.053V falling (UVTH2) - defines 3.3V rail supervision window |
| Reset Timeout | 100ms min / 185ms typ / 320ms max - ensures stable MCU reset hold time after supply recovery |
| Supply Current | 13µA to 30µA at VCC = 3.6V - enables ultra-low-power system monitoring |
| Operating Temp | -40°C to +125°C - supports automotive under-hood and industrial embedded environments |
| Output Types | Push-pull UV, open-drain OV, active-low MR, high-impedance OVLATCH - enables flexible interface with logic and latch circuits |
| Threshold Hysteresis | 0.7% - prevents chatter during slow-moving or noisy supply transitions |
Pinout & Package
MAX6760TALTD3 is housed in an 8-pin TDFN-EP (3mm × 3mm) package with exposed pad (EP) internally connected to GND. Pin 1 is marked by a dot; EP must be soldered to PCB ground for thermal and electrical performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VCC | Primary power input and monitored voltage rail (5V nominal) |
| 2 | GND | System ground reference for all analog and digital circuitry |
| 3 | OVLATCH | High-impedance control input to enable/disable latched OV reporting |
| 4 | VCC2 | Secondary monitored voltage rail (3.3V nominal); powers internal comparator when VCC2 > VCC |
| 5 | SET | Window select input: tied to VCC for ±10% threshold tolerance |
| 6 | MR | Active-low manual reset input with 26kΩ internal pullup to VCC |
| 7 | UV | Active-low push-pull undervoltage output asserted when VCC or VCC2 falls below UVTH/UVTH2 |
| 8 | OV | Active-low open-drain overvoltage output asserted immediately on VCC/VCC2 overvoltage; latched if OVLATCH = high |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent voltage monitoring | Simultaneous supervision of 5V (VCC) and 3.3V (VCC2) rails with separate UV/OV outputs |
| Latched overvoltage reporting | OVLATCH pin enables persistent OV assertion until cleared, critical for fault logging in safety-critical systems |
| Factory-trimmed ±10% window | No external resistor network required; eliminates calibration overhead and board space for precision monitoring |
| 100ms minimum reset timeout | Guarantees sufficient reset pulse width for reliable microprocessor initialization after brownout recovery |
| Low 13–30µA quiescent current | Enables always-on supervision in battery-backed or energy-constrained applications without significant drain |
| Extended temperature operation | Valid functionality across -40°C to +125°C supports under-hood automotive and industrial control environments |
Applications

IC Role / Device Role / Timing Role: Dual-channel supervisor providing independent UV/OV flags to system management controller via open-drain OV and push-pull UV. Use Value: Enables graceful failover by isolating faulty rails before cascading faults propagate across distributed power architecture. |
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 |
|---|---|---|---|
| MAX6761TALTD3 | Identical electrical specs and pinout; differs only in UV output polarity (active-high push-pull vs. MAX6760's active-low) | Requires inverted logic handling in reset signal path; unsuitable where active-low UV is mandatory | Select MAX6761TALTD3 only when system-level reset logic expects active-high UV assertion |
| TLV809E50DBZR | Single 5V supervisor (no VCC2 monitoring), no OVLATCH, no manual reset, SOT-23-3 package | Cannot replace dual-rail function; limited to basic 5V-only monitoring with no latch or secondary rail support | Use TLV809E50DBZR only for cost-sensitive single-rail applications where dual monitoring is unnecessary |
Compared with MAX6761TALTD3, the MAX6760TALTD3 provides active-low UV output compatible with standard reset controllers, while TLV809E50DBZR lacks VCC2 supervision, latch control, and manual reset-making it insufficient for full dual-rail fault coverage.

FAQ
What is the exact VCC and VCC2 threshold configuration for MAX6760TALTD3?
The MAX6760TALTD3 uses suffix "TA" for VCC = 3.3V and "LT" for VCC2 = 5V - but per ordering table and functional description, "TALTD3" decodes as VCC = 5V (L), VCC2 = 3.3V (T), and D3 timeout. Its VCC OVTH is 5.500V–5.750V, UVTH is 4.250V–4.500V; VCC2 OVTH2 is 3.630V–3.795V, UVTH2 is 2.970V–3.053V. These are factory-trimmed values with ±10% window set by connecting SET to VCC.
Does MAX6760TALTD3 support latched overvoltage behavior, and how is it controlled?
Yes, MAX6760TALTD3 supports latched overvoltage reporting via the OVLATCH pin. When OVLATCH is driven high, the OV output remains asserted after an overvoltage event until OVLATCH is pulled low. When OVLATCH is grounded, OV operates transparently (deasserts immediately upon voltage return). This latch function is exclusive to MAX6760/MAX6761/MAX6762 variants and is confirmed in the MAX6760TALTD3 functional diagram and pin description.
What package type and pin count does MAX6760TALTD3 use, and is the exposed pad connected?
MAX6760TALTD3 uses an 8-pin TDFN-EP (3mm × 3mm) package with exposed pad (EP). Per the datasheet pin description, EP is internally connected to GND and must be soldered to a PCB ground plane for optimal thermal performance and electrical stability. This package is distinct from SOT23 variants used by other family members like MAX6757 or MAX6763.
Can MAX6760TALTD3 monitor voltages below 1.0V, and what is its minimum operating VCC?
No, MAX6760TALTD3 cannot monitor voltages below 1.0V. Its VCC operating range is 1.0V to 6.0V, and outputs remain valid down to VCC = 1.0V - but the lowest supported nominal monitored voltage is 0.9V (via MAX6760AA variant with adjustable VCC2). For MAX6760TALTD3 specifically, VCC = 5V and VCC2 = 3.3V are fixed; neither rail is specified below 1.0V, and internal references require ≥1.4V for accurate monitoring.
What is the reset timeout behavior of MAX6760TALTD3, and how does it differ from the D0 option?
MAX6760TALTD3 implements the D3 timeout option: reset deassertion occurs 100ms (min) to 320ms (max) after VCC rises above UVTH or drops below OVTH. This contrasts with the D0 option (20µs typ), which provides fast propagation but no hold time. The D3 delay ensures reliable microprocessor initialization and is factory-configured - not user-adjustable - making MAX6760TALTD3 suitable for systems requiring guaranteed reset pulse width.
