Hi,

As below, switching pulses appear after SS/SD goes low.

Though I suppose to stop switching immediately, is this correct work?

Best Regards,

Hello TQ,

Is the SS/SD scope shot measured right at the SS/SD pin? Can you measure with Short Gnd lead and right at the SS/SD pin and also decrease the scale to 100mV/division ?

Thanks.

David.
