Hi team,
It is nice to know you here. My customer is evaluating our device as below, they find that the EN pin will have Vpp=400mV voltage fluctuation when they apply the PWM signal to the INA/INB pin in below two cases. Customer suspect that our internal circuit causes this issue, could you please help share with me what may cause this abnormal waveform? Thanks.
