High-side current sensor has period output

摘要

You use high-side current monitoring in many battery-powered products that require accurate monitoring of load current, charger current, or both. In applications for nonportable designs, high-side-current monitoring serves as a power-supply watchdog that can flag a failure in downstream devices. The monitoring can also eliminate hazardous conditions by preventing power-supply overloads. Further, high-side-current monitor-ing of motor/servo circuits can produce useful feedback in control applications.
