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.
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,
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 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).
