Hi,
请参阅如下答复:
Are you having one of the MOSFETs getting shorted? Or are you turning on the HS gate connecting VM to SHx? Or is VM and HX pin shorted on the IC? A little lost so would appreciate some clarity.
A short can case excessive current draw so if accidental short is occurring then that needs to be fixed.
Please check the following FAQ section 1 and 3 for help in resolving this.
Thanks
