DESCRIPTION

· The MC34652 is a highly integrated -48V hot swap controller with an internal Power MOSFET, designed for safe board installation and removal from live -48V backplanes without system power-down.

· It features inrush current regulation, programmable current limits, and a disable function for safe load disconnection.

· The device includes programmable under- and overvoltage detection, a start-up delay timer, and active high/low power good signals.

FEATURES

· Integrated Power MOSFET and Control IC in a 16-PIN SOICN package.

· Operates from -15V to -80V input voltage.

· Programmable overcurrent limit with auto retry and independent charging current limit.

· Programmable start-up and retry delay timer.

· Programmable overvoltage and undervoltage detection.

· Active high and low power good output signals.

· Thermal shutdown and Pb-Free packaging.

APPLICATIONS

· Safe hot swap of boards in -48V systems.

· Inrush current control in power supply applications.

· Load management in telecommunications and networking equipment.
