Datasheet Summary
Powered by GS/AI

The A8522KLPTR-T is a multi-channel LED driver designed for automotive applications, featuring a wide input voltage range of 4.5 to 36 V and the capability to withstand load-dump conditions up to 40 V. It integrates an 8-channel current sink configuration, allowing for individually programmable LED currents of up to 60 mA per channel. The device supports I¬=C communication for programming LED currents, PWM dimming, and fault reporting, making it suitable for complex lighting applications. This LED driver includes advanced features such as extensive PWM dimming capabilities with a ratio of up to 10,000:1 at 100 Hz, thermal warning, and derating of LED current at elevated temperatures. It also offers robust fault protection mechanisms, including open/shorted LED detection, input overcurrent protection, and cycle-by-cycle current limiting. The A8522KLPTR-T is packaged in a 28-pin TSSOP with an exposed thermal pad, suitable for applications requiring high reliability and performance in challenging environments.
