The better control timing is as below. Please refer to the circuit diagram in the page 8. VDD PD >100ms >100ms PDPR >350ms Music Power-on sequence Power-off sequence In power-on sequence, the initial state of /PD is low and PDPR is high, and then PDPR sets low after the /PD sets high at least 100ms. In power-off sequence, enable PDPR function and delay 100ms, and then sets low to /PD. POWER DOWN SEQUENCE The power down sequence is a power-save mode (VDD is on), the power down current of MS6330 is less than 1uA. The control timing is as below. PD >100ms Delay time PDPR >350ms Music Disable Power-down Enable Power-down The delay time is decided by the value of the bypass capacitor. It is 5second for 10uF bypass capacitance.
