Description

The TPS92621-Q1 single-channel LED driver includes a unique thermal management design to reduce temperature rising on the device. The TPS92621-Q1 is a linear driver directly powered by automotive batteries with large voltage variations to output full current loads up to 300 mA. Shunt resistor is leveraged to share output current and dissipate power out of the driver. The device full-diagnostic capabilities include LED open, LED short-to-GND circuit, and device overtemperature protection. The one-fails-all-fail feature of TPS92621-Q1 can work together with other LED drivers, such as the TPS9261x-Q1, TPS9262x-Q1, TPS9263x-Q1, and TPS92830-Q1 devices, to address different requirements.
