DESCRIPTION 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.
