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. The internal UVLO function
prevents the LEDs from incorrect operations when the supply voltage is 4V or less. An internal over current
protection function and a thermal protection function are also integrated.
2. Features
Power Supply Voltage 8.0V~24.0V
4.5V~5.5V (connect VIN pin and VDC1 pin)
Oprating Temperature 0 ~ 70C
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/ch
- Open Drain Output 100mA/ch
(Each channel current is less than the value when 15 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)
Protection Function
- Under voltage lock our (UVLO)
- Over current protection (timer latch recovery type)
- Thermal shutdown (automatic recovery)
Package 48-pin LQFP
Application A LED loading machine for the decoration
