MAX16946 LDO / Current Sense Switches

Analog Devices MAX16946 high-voltage, high-side current sense LDO / switches feature internal current limiting to prevent system damage due to fault conditions. The series provides a fixed regulated 8.5V output voltage or an adjustable 3.3V to 15V output voltage. The module can also be configured as a switch. The input voltage range extends from 4.5V to 18V (45V tolerant), making it ideal for providing phantom power to remote radio-frequency LNAs in automotive applications. The MAX16946 monitors the load current and provides an analog output voltage proportional to the sensed load current. Accurate internal current limit protects against overload and short-circuit conditions. A fault-blanking feature allows the devices to ignore momentary faults, such as those caused by the charging of capacitive loads during hot-swapping, preventing false alarms to the system. Analog Devices MAX16946 current-sense LDO / switches are ideal for a variety of applications, including remote LNA phantom power, automotive safety and infotainment, and automotive remote module power.
