The TPS92633-Q1 three-channel LED driver includes an unique thermal management design to reduce temperature rising on the device. The TPS92633-Q1 is a linear driver directly powered by automotive batteries with large voltage variations to output full current loads up to 150 mA per channel. External shunt resistors are leveraged to share output current and dissipate power out of the driver. The TPS92633-Q1 also drives LED units and off-board brightness binning resistors to simplify the manufacturing process and lower whole system cost. Its full-diagnostic capabilities include LED open, LED short-to-GND circuit and single LED short circuit detection.
The one-fails-all-fail feature of TPS92633-Q1 is able to work together with other LED drivers, such as the TPS9261x-Q1, TPS92630/8-Q1, and TPS92830-Q1 devices, to address different requirements.
