TRANSMITTER CONTROL IC
The S-8474 Series is Wireless Power Transmitter Control IC, which is configured with an ON time control circuit, an OFF
time control circuit, a reception detection circuit, a UVLO circuit, a high temperature detection circuit, etc.
Power supply voltage:
VDD = 4.5 V to 6.5 V
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.
tACT = 5.0 ms typ.
tSLEEP = 25.0 ms typ.
TH pin detection voltage is selectable:
0.667 V, 0.577 V, 0.500 V, 0.429 V, 0.370 V
