Allegro Offers Family of Pre-Driver ICs

Allegro MicroSystems Inc. (Worcester, MA) announced it family of pre-driver integrated circuit (IC) products designed to drive external n-channel MOSFETs. The family fills the need for driving either dc brush, or dc brushless motors in systems with motor supply voltages as low as 7 V and as high as 60 V.

The A3925 (18 V to 60 V), A3932 (12 V to 50 V), A3935 (7 V to 40 V), A3938 (12 V to 50 V), A3940 (7 V to 40 V) and A3946 (7 V to 60 V) pre-driver ICs are targeted for the automotive market. The devices feature a wide operating operating temperature range, fault diagnostics and reporting, and operation over a wide supply voltage range. Several of the ICs are designed to fully operate up to 60 V, allowing use in next-generation automotive 42 V systems.

Each IC is offered in various options of surface-mount packages, including some in low-profile and thermally effecient e-LQFP and e-TSSOP packages. The A3925 is priced at $3.59, the A3932 is priced at $3.80, the A3935 is priced at $3.31, the A3938 is priced at $3.91, the A3940 is priced at $2.46, and the A3946 is priced at $1.61.
