When using the chip GIPS30C60-H, a 10k pull-up resistor is used to set SD/OD high and the CIN pin is directly grounded, but there is no three-phase output voltage when the correct pwm signal is input. The chip is used in a motor controller and has a...

When using the chip GIPS30C60-H, sometimes the three-phase bridge switching signal is given but there is no output, regardless of whether the SD/OD pin is set high or not. This chip is used in a motor controller with a 0-270V DC bus supply and input ...
