1_00 The S-8473 Series is Wireless Power Receiver Control IC, which is configured with an overvoltage detection circuit, a charge current control circuit, a VBAT voltage detection circuit, a UVLO circuit, high temperature / low temperature detection circuit, etc.
This IC has a charge function to a small lithium-ion rechargeable battery.
 Features • Power supply voltage: VDD = 2.
2 V to 5.
0 V • Current consumption during charge operation: ISS1 = 250 μA typ.
• VBAT pin current consumption during power-down: IPDN = 1.
0 μA max.
• UVLO detection voltage: VUVLO− = 2.
0 V typ.
• Charge function to a small lithium-ion rechargeable battery Charge current: ILIM = 33 mA typ.
Precharge current: IPRE = 3.
3 mA typ.
Precharge completion voltage: 2.
4 V to 3.
4 V (50 mV step) Charge completion voltage: 4.
0 V to 4.
5 V (50 mV step) Recharge start voltage: 3.
6 V to 4.
45 V*1 Short-circuit detection voltage: 1.
5 V to 2.
0 V (50 mV step) Charge timer function: The charge operation stops after the elapse of 4.
0 hours.
(CCT = 4.
7 nF) The time is settable by connecting an external capacitor to the CT pin.
• High temperature / low temperature protection function: Available by connecting a thermistor to the TH pin.
• Status display function: Available by connecting an external LED to the STATUS pin.
During charge operation: Lighting During charge operation stop: Lights-out During error detection: Blinking • Operation temperature range: Ta = −40°C to +85°C • Lead-free (Sn 100%), halogen-free *1.
Recharge start voltage = charge completion voltage − charge hysteresis voltage (The charge hysteresis voltage can be selected from a range of 0.
05 V to 0.
