Texas Instruments TPS3760A012DYYR

Overview

TPS3760A012DYYR from Texas Instruments is a high-voltage, low-quiescent-current supervisor IC designed for overvoltage/undervoltage monitoring of industrial 12 V/24 V rails. It features a fixed 12 V sense threshold (±1.5% accuracy), 65 V-rated SENSE and RESET pins, 1 µA typical quiescent current, programmable sense delay (1.28 ms to 1.28 s), and push-pull or open-drain reset output. It is used in servo drive functional safety modules where precise rail supervision and latch-capable reset behavior are required.

For engineers reviewing the TPS3760A012DYYR datasheet, TPS3760A012DYYR pinout, TPS3760A012DYYR application, or TPS3760A012DYYR equivalent, this page delivers verified electrical parameters, validated SOT-23-14 pin functions, confirmed timing behavior across –40°C to +125°C, and real-world implementation guidance for industrial power-rail supervision with programmable delays and latch mode.

Technical Context

The TPS3760A012DYYR implements a dual-threshold comparator architecture with independent OV/UV detection on the SENSE pin, using an internal precision voltage reference and trimmed resistor divider. Its SENSE input operates up to 65 V independently of VDD (2.7–65 V), enabling direct monitoring of higher-voltage rails while powered from a lower auxiliary supply.

Reset assertion is controlled by two capacitor-programmable timing channels: CTS sets sense delay (1.28 ms–1.28 s), and CTR sets reset release delay (12.8 ms–12.8 s); both support latch mode activation via the CTS/LATCH pin. The device supports active-low or active-high push-pull and open-drain outputs, with built-in hysteresis options (0.5–2.5 V fixed or 2–13% adjustable) to suppress noise-induced false triggers.

Key Specifications

Pinout & Package

TPS3760A012DYYR is housed in a 4.1 mm × 1.9 mm SOT-23-14 (DYY) package with exposed pad for thermal performance. All GND pins (8, 13) must be electrically connected to PCB ground plane; NC pins (2, 4, 5, 7, 11, 12, 14) must remain unconnected.

FAQ

What is the exact voltage threshold and accuracy of TPS3760A012DYYR?

The TPS3760A012DYYR has a fixed 12 V sense threshold with ±1.5% maximum accuracy over –40°C to +125°C ambient temperature. This value is factory-trimmed using internal resistor dividers and does not require external components. The specification applies to both overvoltage and undervoltage detection windows, with built-in hysteresis configurable from 0.5 V to 2.5 V fixed steps or 2–13% relative to threshold.

Does TPS3760A012DYYR support latch mode, and how is it activated?

Yes, TPS3760A012DYYR supports latch mode via the CTS/LATCH pin (Pin 10). To activate latch mode, drive Pin 10 to ≤1.4 V (e.g., with a 10 kΩ pull-down to GND); once asserted, the RESET output remains active even after the SENSE fault clears. Deactivation requires applying ≥2.1 V to Pin 10 for ≥3 µs while SENSE is within valid range. This behavior is confirmed in Section 6.1 and Figure 6-1 of the official SBVS420A datasheet.

What are the absolute maximum voltage ratings for SENSE and RESET pins on TPS3760A012DYYR?

The SENSE and RESET pins of TPS3760A012DYYR are rated for continuous operation up to 65 V, matching the absolute maximum rating specified in Section 7.1 of the datasheet. This allows direct connection to 48 V and 60 V industrial rails without external clamping diodes. Note that the device contains no internal voltage clamps-external TVS or Zener protection must be added if transients exceed 70 V (absolute max).

Can TPS3760A012DYYR monitor a 24 V rail while powered from a separate 3.3 V supply?

Yes. TPS3760A012DYYR supports independent voltage domains: VDD may be supplied from 2.7–65 V (e.g., 3.3 V auxiliary rail), while SENSE monitors a separate 24 V rail up to 65 V. This decoupling is explicitly supported per Section 3 ("Description") and Section 8.3.1, enabling redundancy in high-reliability systems where VDD and monitored rail sources are physically isolated.

What is the quiescent current of TPS3760A012DYYR at 125°C and 65 V VDD?

At 65 V VDD and +125°C, the TPS3760A012DYYR draws 2.6 µA maximum quiescent current (IDD), with typical value of 1 µA. This is confirmed in Table 7.5 (Electrical Characteristics), where IDD is specified as 1 µA (typical) and 2.6 µA (max) for VIT = 800 mV, and 1 µA (typical) and 2 µA (max) for VIT = 2.7–36 V, across full temperature range including +125°C.
