Automotive high-side dimming rear light reference design

TIDA-00846

Overview

This TI reference design is for an automotive high-side dimmable taillight that uses a BCM to provide the taillight. In this TI reference design, the high-side driver TPS1H100-Q1 is used to output PWM power with different duty cycles. Linear LED drivers TPS92630-Q1 and TPS92638-Q1 are used to drive LEDs with constant current.

characteristic

● High-side dimming
●Wide input voltage range: 9V to 16V, typical 12V
● High-side driver with programmable current limit
● Provide LED open circuit, LED short circuit, LED driver output, battery short circuit, and device thermal shutdown protection
● Thermal foldback function for LED drivers
● Joint failure function
