Texas Instruments TPS92623-Q1 Automotive High-Side LED Driver

Texas Instruments TPS92623-Q1 Automotive High-Side LED Driver is a three-channel device featuring a unique thermal management design to reduce the temperature rising. Automotive batteries directly power the TPS92623-Q1 linear driver with large voltage variations to output full current loads up to 150mA per channel. The external shunt resistors are leveraged to share output current and dissipate power out of the driver. The TPS92623-Q1 driver’s full-diagnostic capabilities include LED open, LED short-to-GND circuit, and device overtemperature protection. The one-fails–all-fail feature of TI TPS92623-Q1 can work together with other LED drivers, such as the TPS9261x-Q1, TPS9262x-Q1, TPS92630/8-Q1, and TPS92830-Q1 devices, to address different requirements.
