LTC4416EMS#PBF

OR Controllers, Ideal Diodes Overview

The LTC4416EMS#PBF is a dual-channel PowerPath controller manufactured by Analog Devices Inc., designed to manage power source selection between two inputs. It utilizes external P-channel MOSFETs to create near-ideal diode functionality for efficient OR-ing of power sources. The device operates within a supply voltage range of 3.6V to 36V and supports an operating temperature range from -40°C to +85°C. Packaged in a space-saving 10-MSOP format, it features low static current consumption of 35µA per channel. Key electrical characteristics include a typical on-state voltage drop of 25mV across the MOSFETs, with turn-on and turn-off delays specified at 60µs and 30µs respectively.
