WIRELESS POWER TRANSMITT
Key Features
Power supply voltage:
VDD = 4.5 V to 6.5 V.
Current consumption:
During operation: ISS1 = 200 A typ. During standby: ISTB = 3.0 A max.
UVLO detection voltage:
VUVLO = 4.1 V typ.
tON time is settable by connecting an external resistor to the RTON pin.
Power saving is possible by intermittent operation during standby time of a receiver module. Active time:
tACT = 5.0 ms typ. Sleep time:
tSLEEP = 25.0 ms typ.
