DC2314A-B

DC2314A-B demonstration circuit features the LTC4236-2 dual ideal diode-OR and single hot swap controller with current monitor. The controller operates in redundant supply circuits, where each rail has an individual ideal diode, and O/P are connected to the load through a single Hot Swap circuit. The controller enables monitoring of the load current by providing a signal that is 100× the sense resistor voltage. The DC2314A allows verification of the LTC4236 Hot Swap and ideal diode functionality during individual rail ramp-up and ramp-down events, during power supply switchover, in steady state, and in overcurrent fault conditions. The main board components are the LTC4236 controller, two power MOSFETs functioning as ideal diodes and one power MOSFET controlled as a Hot Swap switch, two jumpers for enabling the second ideal diode and Hot Swap, four LEDs, 7 banana jacks for connecting power supplies and loads, and many turrets and pads for observing circuit signals.
