The LTC4252BIMS-2#PBF structure is composed of 4 principal functional blocks: dual current sense amplifiers, secondary rectifier driver, power path controller, and POR controller. The dual current sense amplifiers measure the current flowing through a power rail and create a voltage signal that is proportional to the power being fed to the system. The secondary rectifier driver is used to activate the hot swap controller and to provide the gate drive to the external MOSFET, enabling it to correctly regulate the current and voltage flowing through the system. The power path controller is used to control the power on/off status and provide safe load regulation, thereby ensuring reliable system operation. Finally, the programmable overcurrent and short-circuit protection (POR) controller is used to provide protection from over-current and over-voltage conditions.

The LTC4252BIMS-2#PBF is a low-voltage hot swap controller with an operational voltage of up to 6V. It is designed for a wide range of industrial applications and provides a cost-effective hot swapping solution. The device includes a wide variety of features such as adjustable current limit, enable latch, POR, and fast transients response.
