TA8483CP
Three−Phase All wave Driver IC
TA8483CP
The TA8483CP is a three−phase all wave driver IC that makes
possible PWM sensorless driving.
Features
· Built−in excess current detection function
· Built−in heat protection function
Weight: 3.0g (typ.)

5. Output voltage detection circuit (COMP)
· Brings about majority logical sum output. (When
two-phase output or higher out of three-phase
output is larger than mid-point voltage VCC / 2,
"high" is output; when it is smaller, "low" is
output.)
6. Upper side output B-E shunt circuit
· A base-emitter shunt circuit is incorporated to
turn off the upper side power transistor.
