Freescale Semiconductor has announced what it says are the industry's first highly integrated, dedicated ICs intended for motorcycle and scooter applications. By incorporating the 7mm x 7mm SB0400 and SB0401 products into their designs, manufacturers of electronic control units (ECUs) have no need to rely on much larger ABS ICs developed for automobiles, and instead can achieve savings in cost, weight and space, stated the company.

The two-wheel SB0400 IC is designed for motorcycles, while the single-wheel SB0401 IC is intended for scooters and lighter motorcycles. Both products are leadless, and neither require bulky heat sinks. Featuring Freescale's SMARTMOS analogue-mixed signal technology, the devices 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.

The introduction of the products coincides with the upcoming initial implementation of European Commission legislation making the fitment with ABS for all new motorcycles above 125cc to be mandatory beginning 1 January 2016.

Compatible hardware and software between the two ICs greatly reduces system design efforts and enables easy implementation, added Freescale. Integrated hardware safety functions for protection/diagnostics include overvoltage, undervoltage, overtemperature, short and open load detection.

The SB0400 is priced at $3.35 in 10K quantities and the SB0401 is priced at $3.05 in 10K quantities. Both ICs are in volume production and available.
