CONSTANT-CURRENT LINEAR LED CONTROLLER FOR AUTOMOTIVE APPLICATION

“Texas Instruments” Presentation.

CONSTANT-CURRENT LINEAR LED CONTROLLER FOR AUTOMOTIVE APPLICATION

The 3-channel constant-current linear LED controller has been introduced from "Texas Instruments" that is the best for designers for designing quite beautiful in more lighting flexibility. This LED controller introduced for Automotive applications 3-channel high side linear LED Controller without internet MOSFETs. The controller "TPS92831-Q1" always requires the use of external MOSFETs that is often advantageous or at least more convenient than use of fewer external components according to Texas Instruments (TI), TI refers or more believes on use of external MOSFETs because the engineers gain greater flexibility in their automotive lighting designs.

Let's tell you about linear regulators, the car manufacturers get more relaxed from linear constant-current regulators that always help them to meet strict EMC and reliability requirements. The regulators make more lighting effects to the car's brake light, tail light and headlight as bright as the sun. This is the high current power MOSFETs.

This IC requires normal range of temperature that is -40°C to 125°C is considered a wide ambient temperature range for automotive grade. it will have to be protected from faulty channel by the help of short-to-GND and open circuit detection, once it detected, the TPS92831-Q1 runs and disables the faulty channel and enters an automatic retry mode, when the auto-retry mode completed and determines the faulty channel has been resolved then IC resumes normal operation. This controller has the three methods of dimming the LEDs.

These three functions "temperature range" "short-to-GND and open circuit detection" "dimming" are the protection and features for this constant-current linear LED controller.

The automotive application manufacturers should to adopt the said LED controller for taking more powerful results from lighting flexibility because this is the new and latest technology in this regards. The data sheet also describes its functions for lighting effects positively and rather clearly. You can find it more convenient right there in the sheet.
