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.
