Texas Instruments TPS3760E565DYYR

Overview

TPS3760E565DYYR from Texas Instruments is a high-voltage window supervisor IC designed for overvoltage (OV) and undervoltage (UV) monitoring in industrial power rails. It features 2.7 V to 65 V supply range, 65 V-rated SENSE/RESET pins, 1 µA typical quiescent current, ±1.5% voltage threshold accuracy (2.7–36 V), and programmable sense/reset delays via external capacitors. It is used in servo drive functional safety modules to ensure reliable system reset during rail faults.

For engineers reviewing the TPS3760E565DYYR datasheet, TPS3760E565DYYR pinout, TPS3760E565DYYR application, or TPS3760E565DYYR equivalent, key selection criteria include its 65 V input tolerance, latch-capable CTS pin, dual OV/UV detection with configurable hysteresis, and compatibility with noisy 24 V industrial supply monitoring without external resistive dividers.

Technical Context

The TPS3760E565DYYR implements a precision comparator architecture with internal trimmed resistor divider and reference, enabling fixed-threshold operation without external components. Its SENSE and VDD pins operate independently-allowing SENSE to monitor up to 65 V while VDD is powered from as low as 2.7 V-supporting redundant monitoring in high-reliability systems.

It integrates two user-programmable timing channels: CTS (sense delay, 1.28 ms to 1.28 s with 10 nF–10 µF) and CTR/MR (reset delay/manual reset, 12.8 ms to 12.8 s). The CTS pin doubles as a latch enable: driven low (≤1.4 V) to hold RESET asserted after fault clearance, requiring ≥2.1 V for 3 µs to release.

Key Specifications

FAQ

What is the maximum voltage the SENSE pin of TPS3760E565DYYR can withstand?

The SENSE pin of TPS3760E565DYYR is rated for continuous operation up to 65 V, matching its absolute maximum rating. This allows direct connection to 24 V, 48 V, or 60 V industrial rails without external protection components. However, the device lacks internal clamps, so external TVS diodes must be added if transients exceed 70 V (absolute max).

Does TPS3760E565DYYR support both overvoltage and undervoltage detection simultaneously?

Yes, TPS3760E565DYYR functions as a true window supervisor-it detects both overvoltage (OV) and undervoltage (UV) conditions relative to its configured threshold. When SENSE voltage crosses either VITP (OV) or VITN (UV), the device asserts RESET after the CTS delay and holds it for the CTR delay, supporting robust rail integrity monitoring in TPS3760E565DYYR-based designs.

How is latch mode enabled on TPS3760E565DYYR?

Latch mode on TPS3760E565DYYR is activated by driving the CTS pin low to ≤1.4 V (e.g., via 10 kΩ pull-down). Once latched, RESET remains asserted even after the SENSE fault clears. To deactivate, apply ≥2.1 V to CTS for ≥3 µs while SENSE is within threshold-causing RESET to deassert after the CTR delay. This hardware latch is integral to TPS3760E565DYYR's functional safety implementation.

What is the quiescent current of TPS3760E565DYYR across its full operating temperature range?

TPS3760E565DYYR draws 1 µA typical quiescent current at 25°C, with measured values ranging from 0.5 µA to 2.6 µA across –40°C to +125°C and 2.7–65 V VDD. This ultra-low IQ enables battery-backed or energy-harvesting safety monitors to maintain supervision indefinitely without compromising runtime-confirming consistent performance in TPS3760E565DYYR deployments.

Can TPS3760E565DYYR monitor a 24 V rail while powered from a separate 3.3 V supply?

Yes, TPS3760E565DYYR supports independent VDD and SENSE voltage domains: VDD may be as low as 2.7 V (e.g., 3.3 V LDO output), while SENSE monitors up to 65 V (e.g., 24 V motor drive rail). This decoupling enables modular power architecture design and redundancy-key for TPS3760E565DYYR use in safety-critical servo drives where supply isolation is mandated.
