TPS92623QPWPRQ1 has three high-side linear LED outputs, each independently adjustable to 150 mA, and operates from a 4.5 to 40 V supply. Independent current settings and PWM inputs allow separate lamp functions to share one driver. External shunt resistors move part of the dissipation away from the IC, which matters when battery voltage is well above the LED-string voltage.
Fault-bus behavior can be configured for coordinated shutdown or failed-channel-only handling. LED open and short-to-ground diagnostics therefore support different lamp fault policies without changing the basic linear drive topology.
