Hello i'm trying to build the circuit showed on the datasheet of the SM72445 but i have the following questions:
1- If I set the pin A2 to 3.44 V to opperate in low frequency and to use the H-bridge for PM operation. Does that means that the PM_OUT pin becomes useless and i can avoid using the whole circuit related to it? I mean the PM driver and the 2 Transistors?
2- Wich H-Bridge driver would yo recomend me to use? ir2110 is ok? Idon't know if i can use bootstrap because the high side of the bridge couln't opperate in ON state continuously.Could you suggest me a circuit?
somebody has an idea about it? I'm trying to do that circuit but i don't know if i can avoid the PM stage.
to know if you really exit PM stage, check pin PM_OUT. If there are pulses, your circuit is in PM mode.
