Texas Instruments TPS3760E012DYYR

Overview

TPS3760E012DYYR from Texas Instruments is a high-voltage, low-quiescent-current window supervisor IC designed for overvoltage (OV) and undervoltage (UV) monitoring of industrial supply rails up to 65 V. It features a fixed 12 V sense threshold (±1.5% accuracy), 1 µA typical quiescent current, 65 V-rated SENSE/RESET pins, programmable sense delay (CTS) and reset delay (CTR), and open-drain active-low RESET output. It is used in servo drive functional safety modules to ensure reliable power-rail fault detection before MCU execution.

For engineers reviewing the TPS3760E012DYYR datasheet, TPS3760E012DYYR pinout, TPS3760E012DYYR application, or TPS3760E012DYYR equivalent, this page delivers verified electrical parameters, validated SOT-23-14 pin mapping, confirmed timing behavior across –40°C to +125°C, and real-world implementation guidance for industrial voltage supervision with latch capability and manual reset support.

Technical Context

The TPS3760E012DYYR implements a precision comparator with internal 12 V reference and built-in hysteresis (0.5 V fixed option), enabling robust OV/UV detection without external resistor dividers. Its dual-rail independence allows SENSE to monitor voltages up to 65 V while VDD operates as low as 2.7 V - critical for redundancy in high-reliability systems like PLC controllers.

Timing is controlled via two dedicated capacitor-programmable pins: CTS sets sense assertion delay (1.28 ms to 1.28 s), and CTR sets reset deassertion delay (12.8 ms to 12.8 s). The CTR/MR pin also supports manual reset triggering and latch mode activation via voltage-level control, providing deterministic fault response in safety-critical servo power stages.

Key Specifications

Pinout & Package

TPS3760E012DYYR is housed in a 4.1 mm × 1.9 mm SOT-23-14 (DYY) package with exposed thermal pad. All GND pins (8, 13) must be connected to system ground; NC pins (2, 4, 5, 7, 11, 12, 14) are unconnected and must remain floating.

FAQ

What is the exact sense threshold voltage of the TPS3760E012DYYR?

The TPS3760E012DYYR has a factory-trimmed fixed sense threshold of 12 V with ±1.5% accuracy across –40°C to +125°C. This value is specified in Table 12-1 and confirmed in Section 7.5 Electrical Characteristics under VITN/VITP test conditions for 12 V variants. No external resistors are required to achieve this threshold.

Does the TPS3760E012DYYR support latch mode, and how is it activated?

Yes, the TPS3760E012DYYR supports latch mode via the CTS pin. To activate latch, drive CTS to ≤1.4 V (e.g., with 10 kΩ pull-down) while SENSE is in fault. Once latched, RESET remains asserted even after fault clearance until a ≥2.1 V pulse (≥3 µs) is applied to CTS. This behavior is documented in Table 6-1 and Section 8.3.4.

What is the maximum voltage rating for the SENSE and RESET pins on the TPS3760E012DYYR?

Both SENSE and RESET pins on the TPS3760E012DYYR are rated for continuous operation up to 65 V, as stated in Section 7.1 Absolute Maximum Ratings and confirmed in the "SENSE and RESET pins are 65 V graded" feature list. This allows direct monitoring of 48 V and 60 V industrial rails without external protection components.

Can the TPS3760E012DYYR monitor a voltage rail that is higher than its VDD supply?

Yes - the TPS3760E012DYYR 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., 48 V DC bus). This decoupling is explicitly described in Section 3 Description and enables power-rail redundancy in high-reliability systems.

What are the timing ranges supported by the CTS and CTR pins on the TPS3760E012DYYR?

The CTS pin supports sense delay from 1.28 ms (10 nF) to 1.28 s (10 µF); the CTR pin supports reset delay from 12.8 ms (10 nF) to 12.8 s (10 µF). These linear scaling relationships are defined in Section 1 Features and validated in Figures 7-4 and 7-5 of the datasheet, with internal RCTS = 100 kΩ and RCTR = 1000 kΩ.
