TIDA-00846 Reference Design

Texas Instruments

Automotive high-side dimming rear light reference design

Description

The TI design is for automotive high side dimming rear light: which uses BCM to supply the rear light. In the TI design the high side driver TPS1H100-Q1 is used to output PWM supply with different duty cycle. Linear LED drivers TPS92630-Q1 and TPS92638-Q1 are used to drive the LEDs in constant current.

Features
  •  • High side dimming• Wide input voltage range: 12V Typical: 9-16V Continuous• Programable current limit high side driver• LED Open circuit:  LED short circuit: LED driver output short to battery: device thermal shut down protection• Thermal Foldback function for LED driver• One fail all fail function • High side dimming• Wide input voltage range: 12V Typical: 9-16V Continuous• Programable current limit high side driver• LED Open circuit:  LED short circuit: LED driver output short to battery: device thermal shut down protection• Thermal Foldback function for LED driver• One fail all fail function
Applications
