DESCRIPTION  
The Si9979 is a monolithic brushless dc motor controller with  
integral high-side drive circuitry. The Si9979 is configured to  
allow either 60° or 120° commutation sensor spacing. The  
internal low-voltage regulator allows operation over a wide  
input voltage range, 20- to 40-V dc.  
quadrature select, and braking inputs are included for control  
along with a tachometer output. Protection features include  
cross conduction protection, current limiting, and undervoltage  
lockout. The FAULT output indicates when undervoltage, over  
current, disable, or invalid sensor shutdown has occurred.  
The Si9979 provides commutation from Hall-effect sensors.  
The integral high-side drive, which utilizes combination  
bootstrap/charge pump supplies, allows implementation of an  
all n-channel MOSFET 3-phase bridge. PWM, direction,  
The Si9979 is specified to operate over the commercial  
temperature range of 0 to 70°C (C suffix), and the industrial  
temperature range of -40 to 85°C (D suffix).
