TIDA-00846
車用高壓側調光尾燈參考設計
TIDA-00846
概覽
This reference design is for automotive high-side dimming rear light, which uses BCM to supply the rear light. In the 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 LEDs in constant current.
特點
- High-side dimming
- Wide-input voltage range: 12-V typical, 9-V to 6-V continuous
- Programmable current limit high-side driver
- LED-open circuit, LED-short circuit, LED-driver output short to battery, device thermal shutdown protection
- Thermal foldback function for LED driver
- One fail-all-fail function
