LT2940IMS#PBF

Power Management - Specialized Overview

The LT2940IMS#PBF is a high-side current and power monitor IC manufactured by Analog Devices Inc. It measures high-side current and differential voltage, multiplying these signals to output a current proportional to instantaneous power. The device operates on a single supply voltage ranging from 6V to 80V with a typical supply current of 3.5mA. It features complementary open-collector comparators for alarm functions. The component is housed in a 12-lead MSOP package and is rated for an operating temperature range of -40°C to +85°C.
