SC4250 Negative Voltage / Hot Swap Controller

SC4250 Description

Negative Voltage Hot Swap Controller POWER MANAGEMENT .
The SC4250 is a negative voltage hotswap controller that allows the insertion of line cards into a live backplane.

SC4250 Features

* ‹ Programmable slew of the inrush current when ‹ ‹ ‹ ‹ ‹ ‹ ‹ used for hot insertion in the negative 24V and 48V backplane Closed loop operation limits the maximum current even in short circuit condition Built in timer prevents false shutdown when the closed loop operation limits the current Sensing

SC4250 Applications

* ‹ Central office switching ‹ -48V Distributed power systems ‹ Power supply hotswap & inrush control Typical Application Circuit GND C1 0.1 8 PWRGD/PWRGD 1 U1 SC4250 PWRGD /PWRGD VCC GND(remote) R1 562k 2 OV DRAIN 7 Vee VEE R6 18k 3 UV GATE 6 C4 3.3nF C5 150 R2 9.31k 4 VEE SENSE 5 R5 1
