RY4064AT5 from RYCHIP, in a SOT-23-5. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | CHRG | output | Open-drain charge status output pin. Strong pull-down (~10 mA sink capability) during an active charge cycle to drive an LED; weak pull-down (~20 µA) when charging has terminated with valid VCC; high impedance in UVLO. Absolute maximum voltage 10 V. |
| 2 | GND | power_in | Device ground return. Connect directly to the system ground plane for proper thermal dissipation of the internal power MOSFET. |
| 3 | BAT | power_out | Charge current output pin. Connects to the positive terminal of the single-cell Li-Ion battery; regulated to 4.2 V float voltage in constant-voltage mode. Absolute maximum voltage 7 V; typical charge current up to 500 mA. |
| 4 | VCC | power_in | Positive input supply voltage pin (from USB or wall adapter). Recommended operating range 4.25 V to 30 V; 6.4 V typical over-voltage protection threshold; absolute maximum 32 V. UVLO threshold ~3.8 V with ~200 mV hysteresis. |
| 5 | PROG | bidirectional | Charge current program, charge current monitor, and shutdown pin. Connect a resistor RPROG to GND to program charge current (ICHG = 1000 V / RPROG); voltage on this pin mirrors 1/1000 of the BAT current for monitoring. Floating the pin (or forcing >~1.21 V) places the device into shutdown mode. |
