Product Details

TPS92633QPWPRQ1 is a three-channel Texas Instruments automotive high-side LED driver in a 20-pin HTSSOP package, with up to 150 mA regulated independently on each channel.

Separate current-setting resistors and PWM pins let a lamp board assign different brightness and current to three LED strings without forcing them through one common control path.

External shunt resistors share dissipation with the IC when battery voltage exceeds the LED string voltage, and an optional NTC input can derate current as the lamp warms.

Off-board binning-resistor support lets the assembled LED module carry its brightness calibration information, which reduces the need to sort every driver board for a particular LED lot.

Open, short-to-ground and single-LED-short detection with auto-recovery make this option appropriate for automotive lighting that must report a failed string rather than silently lose light.
