The MAX16913/MAX16913A high-voltage high-side current-sense switches feature internal current limiting to prevent system damage due to fault conditions. The input voltage range extends from 5 to 18 V, suiting them for providing phantom power to remote radio-frequency LNAs in automotive applications.
They monitor the load current and provide an analog output voltage proportional to the sensed load current. Features include adjustable current limiting, overcurrent blanking during startup, and a short-to-battery detection every time the internal switch turns on. Fully specified over the –40° to 105°C temperature range, these parts are AEC-Q100 qualified and are available in a 16-pin QSOP package. ($1.50 ea/1,000 — available now.)
