PT16976 is a linear LED controller for automotive exterior lighting. The controller drives an external NPN transistor to regulate a current for LED lamps. The typical application of the device is a rear combination lamps for automotive. A single driver gives the user flexibility to add single channels to multichannel systems. LED brightness can be easily programmed using a single resistor in series with the NPN transistor. It gives the user the flexibility to use the device over a wide range of currents.

A single controller can drive multiple strings of LEDs. The controller provides a dedicated dimming function via the PWM input. Setback current limit function helps to reduce the device power consumption during overvoltage conditions.

Additional fault protection features include open load and short circuit protection, the controller is turned off when an open load or short circuit is detected.
