PS3
– C6 at S0ix
The SoC sends a SVID command SetVID_decay with 0V to enter the PS3 mode. DA6021 switches off all
unnecessary functional blocks minimizing the quiescent current. When detecting an exit from S0ix state, the SoC
sends SetVID_fast/slow and DA6021 recovers VCC to the operating voltage level.
