Description
TPS92623QPWPRQ1 is an automotive-grade, single-channel constant-current LED driver from TI’s TPS926x family. It drives an LED string from a vehicle power line with the current set externally by a resistor. Key features include PWM dimming, and protections such as short-circuit, thermal shutdown, undervoltage, and reverse polarity, delivering robust, efficient regulation. It typically covers a wide automotive input range (roughly 6–40 V) and comes in TI’s compact QPWPRQ1 package suitable for tight LED-module designs. Common applications include automotive exterior and interior lighting (tail/stop lights, indicators) where reliable current control and protection are critical. Benefits are simple BOM, fast dimming, strong protection, and a compact form factor. For exact electrical specs and pinout, consult the datasheet.
Features
Key features of TPS92623QPWPRQ1 (8-pin device):
- 1-channel high-side switch with external-resistor-set LED current regulation
- Automotive input range: suitable for 4.5–42 V systems
- PWM dimming input for LED brightness control (analog dimming not required)
- Protection: undervoltage, overcurrent, short to GND, open-load, and overtemperature with thermal shutdown
- Current-limit protection and soft-start to protect LEDs
- Diagnostic/fault reporting with status flag (fault/open LED/short) and latch option
- Reverse-battery protection and robust ESD protection
- Automotive-grade (AEC-Q100 qualified) with wide operating temperature (-40°C to 125°C)
- Low quiescent current and fast fault response
- Small, simple 8-pin package (QPWPRQ1) suitable for compact LED lighting hardware
Note: LED current is programmable via external sense resistor; device is designed for LED-string applications in automotive environments.

Pinout
- Pin count: 8 pins (PWQFN/QPWPRQ1 package)
- Function: Dual high-side switch for LED drive. Two independent channels with their own inputs and outputs (IN1/OUT1 and IN2/OUT2), powered from VDD with GND, plus enable/diagnostic and protection features (e.g., short-circuit/thermal). PWM dimming is achieved via the control inputs.
