Automatic changeover circuit

Automatic Changeover Switch using IC LTC4412 from Linear Technologies. This Automatic changeover circuit using IC LTC4412 can be used for the automatic switchover of a load between a battery and a wall adapter.LTC4412 controls an external P-channel MOSFET to create a near ideal diode function for power switch over and load sharing.

This makes the LT4412 an ideal replacement for power supply ORing diodes. A wide range of MOSFETs can be driven using the IC and this gives much flexibility in terms of load current. The Automatic changeover Switch circuit also has a bunch of good features like reverse battery protection, a manual control input, MOSFET gate protection clamp etc.
