Tool/software:
Hi Team,
PIN7 has a 5V input, PIN2 has a 3.3V input, and PIN8 has a 20V input.
INHA, INLA, INHB, INLB, INHC, and INLC have square wave signal inputs.
But there is no voltage output of 3.3V on pin 17, and no signal output on pins 10-12.
Please help to check the schematic diagram for any issues and analyze the cause,
