Si9979CS Datasheet (TEMIC) - 3-Phase Brushless DC Motor Controller

Si9979CS, 3-Phase Brushless DC Motor Controller

The Si9979CS is a monolithic brushless dc motor controller with integral high-side drive circuitry.

The Si9979 is configured to allow either 60 0 0r 120° commutation sensor spacing.

The internal low-voltage regulator allows operation over a wide input voltage range, 20- to 40-V dc.
