Table 3. VOP/VON Shutdown Discharge Selection with SWIRE Pulse

Pulse

21

Enable

Once pulse 21 received on SWIRE pin, the RT4723 will enable the discharge function to discharge the VOP/VON

outputs for 20ms and then enter high impedance state when fault or power-off condition. The discharge function

is default disabled and outputs keep high impedance state when fault or power-off condition .
