... To reduce the pop noise, turn OFF power supply while controlling in the following timing (PWM=BD mode). Protection Circuit LV4924VH incorporates the over-current protection circuit, thermal protection circuit, supply voltage drop protection circuit and output offset detection protection circuit. Activation of any one of these circuits causes the SOS output pin to become active and thus " ...
