产品详细说明

TPS92610QPWPRQ1 is a Texas Instruments single-channel automotive linear LED driver in a 14-pin HTSSOP package, capable of regulating up to 450 mA through one LED string.

An external sense resistor sets the constant current, and a PWM input adjusts light output without requiring a separate current-regulation loop on the vehicle lighting board.

The 4.5 to 40 V supply span covers a battery-connected input, while an external resistor can share heat with the IC when the LED forward voltage leaves a large drop across the driver.

Open-string, short-circuit and single-LED-short diagnostics report faults that would otherwise be hard to distinguish from a simple loss of brightness.

Its configurable fault bus can coordinate several drivers in one lamp, including an all-off response when the lighting function requires paired strings to fail together.
