[AP4203] AP4203 15ch 100mA LED Driver IC 1. General Description The AP4203 is a 15 channel LED Driver that supports 2 types of serial interfaces (SCI serial interface or serial F/F cascade interface) to program LED lighting. The built-in 100mA drivable power MOSFET is used to shut off the LED current, and LEDs are controlled by a PWM method in accordance with the LED gradation data that is programmed into the device. Constant current output and Open drain output are selectable by DRSET setting pin. To reduce wirings in the system, voltage on anode side of LEDs can be communized. A maximum of 32 devices can be connected on a single BUS to a common master device; furthermore, each AP4203 retains its own programmed commands allowing continuous autonomous lighting.
