概述

Description

The TPS92623QPWPRQ1 is a TI automotive-grade, multi-channel LED driver IC designed to drive several LED strings from a vehicle supply with regulated current per channel. It typically offers programmable output current per channel (via an external sense resistor), PWM dimming, and comprehensive protections (LED open/short, overcurrent, undervoltage, thermal). It operates over a wide automotive input range and helps reduce BOM by integrating multiple current sinks in one package. The QPWPRQ1 suffix indicates a RoHS-compliant QFN package with automotive qualification. Typical applications include automotive exterior and interior lighting such as tail/stop lamps, indicators, and backlighting. For exact channel count, current ranges, dimming interface, and pinout, consult the TPS92623 datasheet and TI product page.

Features

Here are the general features of TPS92623QPWPRQ1 (automotive LED driver):
- 2-channel high-side constant-current LED driver
- Independent current regulation per channel with external sense resistor
- Dimming options: PWM dimming and analog dimming
- Wide input voltage range suitable for automotive applications
- Protection: open/short LED protection, overcurrent, overvoltage, short-circuit protection
- Thermal shutdown and thermal protection
- UVLO / supply monitoring
- Fault/diagnostic status reporting
- Automotive-grade (AEC-Q100 qualified), RoHS compliant
- Small-package option (QFN) with robust ESD and protection features
Note: For exact electrical specifications (current range, tolerances, timing, and pinout), please refer to the official datasheet.

Package

QFN-16 (4×4 mm) package, wettable-flank variant (QPWPRQ1).

Pinout

- Pin count: 24-pin device in the PWPR package (automotive-grade, QFN style).
- Function: Automotive high-side LED driver with two independent constant-current LED channels. It provides programmable LED current, supports PWM and analog dimming, and includes protections (overcurrent, overtemperature, UVLO, open/short LED).

Manufacturer

- Manufacturer: Texas Instruments (TI).
- What kind of company: TI is a global semiconductor company that designs and manufactures analog and embedded processing integrated circuits for automotive, industrial, consumer electronics, and communications markets.

Application

TPS92623QPWPRQ1 is a multi‑string constant‑current LED driver. Typical application areas include:
