Automotive High-Side Dimming Rear Light

The car lights are significant parts of a car system. The reference design is an automotive high-side dimming rear light. The board is composed of the main component TPS1H100-Q1, high-side power switch with an integrated NMOS power field-effect transistor (FET) and charge pump. The TPS92630-Q1 and TPS92638-Q1, is a three-channel linear and eight-channel linear LED driver, respectively. The reference design also comes with a TPS7B6950, which is a high voltage LDO regulator. The TLC555-Q1 is timer that generates the PWM input for the high-side driver. This reference design uses a body control module (BCM) to supply the rear light system. Read more
