DC motor drivers support functional safety features

December 02, 2013 // By Christoph Hammerschmidt
With two new DC motor driver ICs, Toshiba Electronics Europe (TEE) expands its line-up of such devices for automotive applications. The ICs integrate multiple abnormality detection circuits, which help to improve the functional safety of automotive systems. These include overcurrent detection, overtemperature detection, overvoltage detection, and undervoltage detection.

Automotive applications that use small motors, such as control of air-conditioner valves and door mirrors, require low power consumption driver ICs. The new motor drivers - type designations TB9101FNG and TB9102FNG - are fabricated with the low power consumption, fine pitch BiCD process - a wafer-level process that integrates bipolar, CMOS and DMOS (Double-Diffused MOS). This process ensures low on-resistance and reduced power consumption. The respective on-resistances are TB9101FNG 0.6Ω (Typ.) and TB9102FNG 0.5Ω (Typ.).

Adoption of a small sized SSOP24 package (5.6 x 7.8mm) reduces the mounting area to approximately 1/3 that of equivalent products, contributing to the downsizing of PCBs.

The TB9101FNG can drive two motors and TB9102FNG can drive up to six motors, allowing selection to meet the number of motors required for applications. Mass production is scheduled to start in February 2014.
