Brushed DC motor drive ICs for automotive applications

December 03, 2013 // By Graham Prophet
Toshiba Electronics Europe (TEE) has announced TB9101FNG and TB9102FNG, small-sized brushed DC motor drivers for automotive applications including control of air-conditioner valves and door mirrors

Automotive applications that use small motors require low power consumption driver ICs. The new motor drivers are fabricated with a low power consumption, fine pitch BiCD process, and have low on-resistance. The respective on-resistances are TB9101FNG: 0.6Ω (typ.) and TB9102FNG: 0.5Ω (typ.).

A small sized SSOP24 package (5.6 x 7.8mm) reduces the mounting area to approximately 1/3 that of equivalent products. The ICs integrate multiple abnormality detection circuits, including 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.
