Freescale specs analog IC for motorcycles' ABS

October 06, 2015 // By Julien Happich
Measuring only 7x7mm, Freescale Semiconductor’s SB0400 and SB0401 analog ICs were specifically engineered for motorcycle and scooter’s anti-lock braking systems (ABS), helping ECU manufacturers reduce the cost, size and weight of the electronic control units.

The two-wheel SB0400 IC is designed for use with motorcycles, while the single-wheel SB0401 IC is intended for scooters and lighter motorcycles. Both products are leadless, and neither require bulky heat sinks, saving system cost and space.

Built on Freescale’s SMARTMOS analog-mixed signal technology, they integrate an ABS system’s wheel speed sensor interface, valve drivers, motor pump driver, safety switch and safety state machine into the smallest package size available on the market for motorcycle and/or scooter designs.

This product introduction coincides with the upcoming initial implementation of European Commission legislation making ABS mandatory for all new motorcycles above 125cc, beginning 1 January 2016. Integrated hardware safety functions for protection/diagnostics include over-voltage (OV), under voltage (UV), over temperature, short and open load detection.
