LTC4235CUFD-2#PBF

Hot Swap Controllers Overview

The LTC4235CUFD-2#PBF is a hot swap voltage controller manufactured by Analog Devices Inc., housed in a 20-pin QFN package. It integrates dual ideal diode OR controllers for 12V rails and a single hot swap controller with current monitoring. The device operates within a supply voltage range of 2.7V to 18V, drawing a typical operating supply current of 2.7 mA. Designed for surface mount installation, it supports redundant power architectures where individual ideal diodes manage input rails while the hot swap circuit protects the load connection.
