Overview
The ADM4210-1AUJZ-RL7 is a hot swap controller produced by Analog Devices Inc. This device is designed to safely enable the insertion and removal of a printed circuit board from a live backplane, preventing damage from excess currents. It operates over a supply voltage range of 2.7 V to 16.5 V and features an undervoltage lockout circuit to ensure proper operation. The ADM4210-1AUJZ-RL7 uses an external N-channel power MOSFET with a current control loop and an internal charge pump to enhance the gate of the MOSFET. It is available in a 6-lead TSOT package and is pin compatible with the LTC4210-1 and LTC4210-2.
