1、SW3003 is an integrated circuit for ABS / ESC application.

2、Advantage of SW3003.
- Switching regulator and linear regulator supply power to internal circuit, external MCU, and IO.

3、Pump main switch driver controls external N-MOSFET by PWM control. Valve main switch driver is high-side pre-driver for controlling main switch of solenoid valve by ON/OFF control.

4、2-channel warning lamp driver turns on or off the warning lamp.

5、4-channel wheel speed sensor interface supplies power to wheel speed and provides wheel speed information for main MCU and external ECU.

6、CAN transceiver makes it possible to communicate with external ECU.

7、4-channel ADC converts hydraulic information coming from external hydraulic sensor into digital value and provides it to the main MCU.
