Product Details

TPS92611QDGNRQ1 is the eight-pin HVSSOP version of Texas Instruments' automotive single-channel linear LED driver, regulating as much as 300 mA for one high-side LED string.

The sense resistor establishes current and the PWM control pin sets brightness, so the same device can serve several lamp-current targets without changing the control method.

Its 4.5 to 40 V input range suits vehicle-battery operation, and an external heat-sharing resistor gives the board designer a way to move dissipation away from the driver package.

Open-circuit and short-circuit detection with auto-recovery helps the lamp controller tell an LED or wiring fault from an intentional dimming command.

A configurable shared fault bus supports coordinated shutdown or only the affected channel turning off across multiple automotive drivers.
