Description
The AP4202 is a 9 channel LED Driver that supports 2 types of serial interfaces (SCI serial interface or serial F/F cascade interface) to program LED lighting.
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, LEDR0~2, LEDG0~2, LEDB0~2).
- 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/ch - Open Drain Output 100mA/ch (Each channel current is less than the value when 9 channels are set simultaneously).
- LED Gradation 8-bit PWM gradation method (256 gradation).
- Built-in PWM Generator, Adjustable PWM Period.
- Simultaneous lighting-off function (SCI interface).
- Prote.
