The Texas Instruments TPS92633QPWPRQ1 is an automotive-qualified three-channel high-side LED driver with thermal sharing and off-board binning support, supplied in a 20-pin HTSSOP package measuring 6.5 mm by 4.4 mm with a 1.2 mm height. The HTSSOP body includes an exposed thermal pad, which is what allows a linear driver to shed the heat it generates when regulating current. TI lists the part as in Production. Thermal sharing distributes dissipation across the driver and an external ballast device so that the LED string can run over a wider input range without thermal shutdown.

Automotive high-side LED drivers of this type run exterior and interior lighting where the current in each string must be held constant despite a varying battery rail: rear combination lamps, daytime running lights, position and turn indicators, and interior ambient lighting. Off-board binning lets the same driver be matched to the specific LED bin fitted to a lamp module, so brightness is consistent across production units without a firmware change. Buyers are automotive tier-one lighting suppliers and lamp module manufacturers. Only seven attributes are recorded for this product and all of them describe the package, so confirm channel current, input voltage range and thermal ratings against the TI datasheet.
