Selecting External Components for an Automotive Remote Antenna Regulator and Current-Sense Amplifier
The MAX16946, is a high-voltage regulator with a precision current-sense amplifier (CSA), designed to provide phantom power to remote radio antennas in automotive applications. The device provides short-circuit protection, current-limit protection, and open-load detection. The current levels for current-limit protection and open-load detection are programmable with external resistors. To ensure that antenna detection circuitry meets performance objectives, the design engineer must choose the correct external components for the design.
