Texas Instruments TPS3760E012DYYRQ1

Overview

TPS3760E012DYYRQ1 from Texas Instruments is an AEC-Q100 Grade 1 automotive-grade high-voltage supervisor IC designed for overvoltage monitoring of 12V/24V battery rails. It features a fixed 800mV sense threshold (±1% accuracy), 2% hysteresis, open-drain active-low reset output, and operates across 2.7V–65V supply range with 1µA typical quiescent current. Used in telematics control units to prevent MCU malfunction during battery transients.

For engineers reviewing the TPS3760E012DYYRQ1 datasheet, TPS3760E012DYYRQ1 pinout, TPS3760E012DYYRQ1 application, or TPS3760E012DYYRQ1 equivalent, this page delivers verified electrical specs, SOT-23-14 pin functions, automotive thermal performance (–40°C to +125°C), and real-world timing behavior for cold-crank transient immunity.

Technical Context

The TPS3760E012DYYRQ1 implements a dedicated overvoltage detection architecture with independent VDD and SENSE pins-enabling monitoring of higher-voltage rails (e.g., 48V battery) while powered from a lower-voltage domain. Its internal reference and resistor ladder eliminate external components for the 800mV threshold variant, reducing BOM count and leakage error.

Timing is controlled via two capacitor-programmable pins: CTS sets sense delay (1.28ms–1.28s), and CTR sets reset release delay (12.8ms–12.8s). The device supports manual reset via CTR/MR and includes built-in hysteresis to reject noise-induced false triggers during engine start-stop cycles.

Key Specifications

Pinout & Package

TPS3760E012DYYRQ1 is housed in a 14-pin SOT-23 (DYY) package measuring 4.1mm × 1.9mm, optimized for space-constrained automotive PCBs. All GND pins (8, 13) must be connected to system ground; NC pins (2, 4, 5, 7, 11, 12, 14) are internally unconnected and must remain floating.

FAQ

What is the exact overvoltage threshold voltage of the TPS3760E012DYYRQ1?

The TPS3760E012DYYRQ1 has a fixed overvoltage threshold of 800mV ±1% across –40°C to +125°C ambient temperature. This value is factory-trimmed and does not require external resistor configuration. The 800mV setting enables direct use with external voltage dividers for higher-rail monitoring (e.g., 12V or 24V), and its tight tolerance ensures reliable detection during battery transients without calibration.

Does the TPS3760E012DYYRQ1 support undervoltage detection?

No, the TPS3760E012DYYRQ1 is configured exclusively for overvoltage (OV) detection, as indicated by the "E" prefix in its part number per TI's nomenclature. It cannot monitor undervoltage conditions. For combined UV/OV supervision, TI recommends the TPS3762-Q1, which supports both thresholds in a single device and includes latch functionality.

What package type and dimensions does the TPS3760E012DYYRQ1 use?

The TPS3760E012DYYRQ1 uses the SOT-23-14 (DYY) package with nominal body dimensions of 4.1mm × 1.9mm. It is distinct from the WSON-10 (DSK) variant and is not pin-compatible with it. The DYY package exposes two GND pins (8 and 13) for improved thermal and electrical grounding in automotive PCB layouts.

How is reset timing controlled on the TPS3760E012DYYRQ1?

Reset timing on the TPS3760E012DYYRQ1 is controlled by two external capacitors: CTS sets the sense delay (time from OV detection to RESET assertion), and CTR sets the reset release delay (time from OV clearance to RESET deassertion). With 10nF, CTS yields 1.28ms and CTR yields 12.8ms; scaling to 10µF extends both to 1.28s and 12.8s respectively. Internal timing resistors are factory-trimmed for ±12% accuracy.

Is the TPS3760E012DYYRQ1 qualified for automotive safety applications?

Yes, the TPS3760E012DYYRQ1 is AEC-Q100 Grade 1 qualified (–40°C to +125°C ambient) and explicitly labeled "Functional Safety-Capable." Texas Instruments provides FIT rate data, FMEA reports, and safety manuals to support ISO 26262 ASIL-B system-level integration-making it suitable for safety-related vehicle functions including instrument clusters and telematics.
