Switch Hall IC
SDC477
Function Description
The figure below is the circuit diagram of H-bridge
transistors. The single-phase motor rotation depends on a
switching current of coil L1. When the magnetic pole is N
pole, Q2, Q3, Q5 are turn-off and Q1, Q4, Q6 are turn-on,
L1 has a current from DOB to DO. And when the magnetic
pole is S pole, Q1, Q4, Q6 are turn-off and Q2, Q3, Q5 are
turn-on. There is a current from DO to DOB between L1.
