BA6796FP Description
%Supply voltage drop muting& The internal circuits turn off when the supply voltage drops below 4.3V (typically), and turn on again when it rises above 4.5V (typically). FElectrical characteristic curves %Bias drop muting& Muting also occurs when the bias pin voltage (26 pin) is lowered below 1.4V (typically). Be sure the voltage stays between 1.6V and 6.5V during normal operation.
