DC1676A: 20A OR'ing or Dual Diode, 4.5 ~ 60V in

Summary

Demonstration Circuit 1676A showcases the LTC®4359 ideal diode controller with reverse input protection. The board includes two independent LTC4359 ideal diode circuits, sharing a common ground and operating over a 4.5V to 60V range. Each circuit comprises a load switch and ideal diode connected in series. Power to the load may be turned on and off by using the SHDN input, and the load is protected against reverse inputs of up to –40VDC by the ideal diode.

In addition, input dropouts are blocked from the output, permitting capacitors or a battery to hold up the load when input power fails.

Each channel is capable of carrying 20A. Through-hole pads are included to permit modification for even higher currents, using an off-board power stage.
