Current Sense Switches Target Remote RF LNAs

For automotive-grade designs, the MAX16913 and MAX16913A high-voltage current-sense switches prevent system damage due to fault conditions. The devices monitor load current and provide an analog output voltage proportional to the sensed load current. Features include internal current-limiting circuitry, two open-drain fault-indicator outputs, an input supply voltage range from 5V to 42V, a fault-blanking feature, thermal-overload protection, short-to-battery detection during startup, and an enable control. AEC-Q100 qualified and available in 16-pin QSOPs, pricing starts at $1.50 each/1,000. MAXIM INTEGRATED PRODUCTS, Sunnyvale, CA. (800) 998-8800.
