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.
