LTC4235IUFD-1#PBF

Hot Swap Controllers Overview

The LTC4235IUFD-1#PBF is a hot swap voltage controller manufactured by Analog Devices Inc., housed in a 20-pin QFN package. It integrates two 12V ideal diode-OR controllers and one hot swap controller with current monitoring capabilities. The device operates within a supply voltage range of 2.7V to 14V, drawing a typical quiescent current of 2.7mA. Designed for surface-mount installation, it supports adjustable current limiting and retry functions, making it suitable for robust power distribution systems requiring precise control and protection.

Hot Swap Controllers Feature Summary

• Integrates dual 12V ideal diode-OR controllers for seamless power path management
