Toshiba Launches Small Sized Brushed DC Motor Driver ICs for Automotive Applications

News

Toshiba Electronics Europe (TEE) has announced TB9101FNG and TB9102FNG, the latest additions to its line-up of small sized brushed DC motor drivers for automotive applications. 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 are fabricated with the low power consumption, fine pitch BiCD process, and realize low on-resistance, reducing 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 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. 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
