Advance Information

ABS motorcycle braking chip

33SB0400

The SB0400 is an antilock brake controller designed for use in harsh motorcycle

environments.

It has four high-current low-side drivers for use with solenoid valves, two

configurable wheel speed sense inputs capable of handling active sensors, and

high-side gate drivers for controlling two external N-channel MOSFETs for use

with a pump motor and master relay for solenoid coils. Along with this main

functionality, the SB0400 also has a warning lamp driver and a K-line transceiver.

The SB0400 boosts an internal charge pump, allowing the high-side drivers to

use inexpensive N-channel MOSFETs. The digital I/O pins can be configured for

both 5.0 V and 3.3 V levels for easy connection to any microprocessor. The

SB0400 uses standard SPI protocol for communication.

MOTORCYCLE BRAKING CHIP

The SB0400 is a solution for ABS braking application, and powered by

SMARTMOS technology.
