AP4203 Datasheet Led Driver

Manufacturer: AKM (Asahi Kasei Microdevices)

Overview: [AP4203] AP4203 15ch 100mA LED Driver IC 1. General.

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.

Key Features

  • Power Supply Voltage 8.0V~24.0V 4.5V~5.5V (connect VIN pin and VDC1 pin).
  • Oprating Temperature 0 ~ 70C.
  • Absolute Maximum Voltage 30V (VIN, LEDR4~8, LEDG4~8, LEDB4~8).
  • 2 Types of Serial Interface for Setting Lighting Data - 4-wire SCI interface (maximum communication clock: 5MHz) - Serial-F/F cascade (maximum communication clock: 10MHz) - Applicable to both 3.3V and 5.0V input signal (output is fixed to 5.0V).
  • LED Current maximum 100mA/ch - Constant Current Output 50mA/.
