TI’s New Automotive LED Lighting Controller


Automotive 3-Channel High-side High-Power Constant-Current Linear LED Driver. Texas Instruments (TI) introduced the first 3-channel high-side linear automotive light-emitting diode (LED) controller without internal MOSFETs which gives designers greater flexibility for their lighting designs. With the trend of better lighting homogeneity, high-current LEDs are often used in automotive front and rear lamps with lighting diffusers and light-guides. Meanwhile, in order to meet strict EMC and reliability requirements, linear LED drivers are popular in automotive applications. However, it is a challenge to deliver high current for linear LED drivers with integrated power transistors. The TPS92830-Q1 device is an advanced automotive-grade high-side constant-current linear LED controller for delivering high current using external N-channel MOSFETs. The device has a full set of features for automotive applications and is compatible with a wide selection of N-channel MOSFETs. http://www.ti.com/tps92830q1-pr
