The TIDA-01183 TI Design details a solution on how to use pulse width modulation (PWM) to dim an automotive headlight or tail light with a precision of better than 2% duty cycle without the necessity of using a micro controller. This allows the design to be very cost competitive. Devices used in this design are the TPS92691-Q1 multi-topology LED Driver in boost and boost to battery configuration controlling the LEDs. The TLC555-Q1 LinCMOS timer, together with the OPA2377-Q1 operational amplifier, measure and generate an accurate PWM signal by applying a feedback loop and a precision shunt regulator for setting the duty cycle accurately. The designs input stage is EMI/EMC filtered and can be directly supplied by the cars battery.

The TIDA-01381 TI Design details a solution on how to drive a string of matrix LED headlights, measure the temperature of the LEDs, and implement support for thermal foldback, which reduces the current in the LEDs as the LED temperature rises to prevent damage to the LEDs. The design uses TI temperature sensing solutions instead of negative temperature coefficient (NTC) thermistors in order to reduce the number of components, number of physical wires, and reduce number of pins used on microcontroller. This TI Design should be interfaced with a microcontroller to do the thermal foldback current derating of the LEDs. The input stage of the design includes electromagnetic interference (EMI) and electromagnetic compatibility (EMC) filters and can be directly supplied by a car battery.
