The TPS92629-Q1 single-channel LED driver includes a unique thermal management design to reduce temperature rising on the device. The TPS92629-Q1 is a linear driver directly powered by automotive batteries with large voltage variations to output full current loads up to 250 mA. External shunt resistors are leveraged to share output current and dissipate power out of the driver. The device’s full-diagnostic capabilities include LED open, LED short-to-GND, LED short-to-battery circuit and device overtemperature protection. The high accuracy and optimized slew rate of analog dimming control supports off board long wire driving with enhanced EMC performance and eliminates the flick and afterimage issue. The multiple fault could be reported out by different voltage levels through fault pins for safety critical applications.
