Low level, positive supply adjustment circuit and interface protective circuit are closed.(3) when positive supply breaks down, (open circuit is short over the ground
Road), N_EN signal and EN signal export low level, and EN signal is low level, then power supply regulator circuit is closed；Although N_EN believes
Number be low level when, interface protection chip allows to be connected, but due to interface protective circuit lost power supply supply, input and output
It is still off-state, defencive function can be played.Since the closing velocity of power supply regulator circuit is in musec order, negative pressure monitoring
The control signal of circuit output simultaneously closes off the modulation power source for being supplied to transmitting branch amplifier, to accelerate closing velocity, thus
Realize the protection to component internal device.
