High-Side Positive Current Sensor Monitors Negative Supply


关键词: current sensor, negative supply, current sense amplifier, negative current monitor, current sense amp, current monitor


Abstract: This application note uses a high-side current-sense amplifier to monitor the current from a negative supply voltage. The circuit uses the IC's wide common-mode input range to amplify a small Vsense signal at the negative supply and level shift it up to a positive output voltage.
