Si9979CS Datasheet | TEMIC Semiconductors

Features - Hall-Effect mutation - 60- or 120- Sensor Spacing - Integral High-Side Drive for all N-Channel MOSFET Bridges - PWMInput - Quadrature Selection - Tachometer Output - Reversible - Braking - Output Enable Control - Cross Conduction Protection - Current Limiting - Undervoltage Lockout - Internal Pull-Up Resistors Description 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° mutation sensor spacing. The internal low-voltage regulator allows operation over a wide input voltage range, 20- to 40-V dc. The Si9979CS provides mutation from Hall-effect sensors. The integral high-side drive, which utilizes bination bootstrap/charge pump supplies, allows implementation of an all n-channel MOSFET 3-phase bridge. PWM, direction, quadrature select, and braking inputs are...
