9.4.4 Device Soft Mute

Asserting CMUTE low initiates the device soft mute function. The soft mute function initiates a ramp down sequence of the outputs, and the output FETs go into a Hi-Z state after the ramp down is complete. All internal circuits are powered while in soft mute state. External control of the soft mute function must provide high impedance output when not engaged (open drain output) to allow the CMUTE node to charge/discharge during device ramp up and ramp down when de-asserting and asserting RESET.
