Shut Down a Current-Sense Amplifier via Its Supply Pins


关键词: current-sense amplifiers, battery operation, NMOS transistors, shutdown


Abstract: You can shut down a current-sense amplifier by connecting an NMOS transistor in its ground path and driving it with logic-level signals capable of turning the transistor ON and OFF. When ON the amplifier operates normally, but when OFF it shuts down because its ground is floating.
