System checkout when the power supply and battery are connected and the low loss pwrgate is powering a load a quick check out is as follows.
Low loss power gate.

P drv is the total gate drive loss divided to calculate the driver loss r ghi is turn on of the driver.
Simply turn on your equipment then unplug the power supply.
Usb port access to monitor system or to change charge.
This keeps the power losses to a minimum.

The low loss pwrgate uses mosfet power transistors to switch the load between power sources with less then a 20 milivolt drop much smaller then similar systems that use schottky diodes.

Epic pwrgate is a 12 volt backup power system rated at 40 amperes continuous from either a power supply or a battery.
Connected equipment will instantly switch to battery during a power blackout or power supply failure.
Design based on powerpath controller and low loss mosfets on status resistance 0 0023 ohm you do not have to add heatsinks even for 30 amps of continuous working current.
Epic pwrgate is a 12 volt backup power system rated at 40 amperes continuous from either a power supply or a battery.
In previous studies power circuits using the cascode device achieved higher power density than circuits using only a sic device but.
Uses two 80 ampere schottky diodes as an or gate to isolate the battery and power supply from each other.
Connect the communications equipment to the low loss pwrgate and enjoy knowing you now have full backup power.
Low loss pwrgate provides forward voltage drop of only 0 05 volts.
Like sic devices it also has relatively high voltage rating and low c oss energy loss at high frequencies.
Like gan devices the cascode gan sic device is easy to drive at high frequencies and has low gate loss.
The low loss pwrgate transfers up to 25 amperes at up to 16 volts dc continuously.
Low loss pwrgate provides forward voltage drop of less than 0 3 volts at 20a and 0 37 volts at 40a.
