Estimating power loss in a gate driver ic static power loss static level shifter loss.
Low loss power gate.
This keeps the power losses to a minimum.
It depends on the gate electric charge or the gate capacity of the high side mosfet and low side mosfet.
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.
Connected equipment will instantly switch to battery during a power blackout or power supply failure.
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.
Uses two 80 ampere schottky diodes as an or gate to isolate the battery and power supply from each other.

Connected equipment will instantly switch to battery during a power blackout or power supply failure.
Low loss pwrgate provides forward voltage drop of only 0 05 volts.
Where does power dissipate.
Gate charge loss is calculated using the following formula.
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.
Simply turn on your equipment then unplug the power supply.
Like gan devices the cascode gan sic device is easy to drive at high frequencies and has low gate loss.
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.

Low loss pwrgate provides forward voltage drop of only 0 05 volts.
As shown by equation 6 gate drive losses do not all occur on the mosfet.
Gate driver add to the power dissipation losses.
Usb port access to monitor system or to change charge.
Low loss pwrgate provides forward voltage drop of less than 0 3 volts at 20a and 0 37 volts at 40a.
Connect the communications equipment to the low loss pwrgate and enjoy knowing you now have full backup power.
Like sic devices it also has relatively high voltage rating and low c oss energy loss at high frequencies.
