RYCHIP · Battery Management · ESOP-8
RY4056AP8 from RYCHIP, in a ESOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | TEMP | input | Battery temperature detection input; if TEMP is directly grounded, the battery temperature detection function is cancelled and the other functions remain normal. Absolute maximum voltage is -0.3V to 10V. |
| 2 | PROG | bidirectional | Charge current program, charge current monitor and shutdown pin: a program resistor to ground sets the charge current (IBAT = 1000 × VPROG / RPROG, with VPROG nominally 1.0V), and floating the pin enters manual shutdown. Voltage range is -0.3V to VCC+0.3V. |
| 3 | GND | power_in | Ground pin. |
| 4 | VCC | power_in | Positive input supply voltage pin; input supply range is 4.25V to 6.5V, with undervoltage lockout threshold of 3.7V to 3.92V and absolute maximum of 10V. |
| 5 | BAT | power_out | Charge current output pin to the battery; BAT pin current is rated 1000mA maximum and BAT voltage absolute maximum is 7V. |
| 6 | STDBY | output | Battery charge completion indicator output; absolute maximum voltage is -0.3V to 10V. |
| 7 | CHRG | output | Open-drain charge status output: strong pull-down (~10mA) during a charge cycle, weak pull-down (~20µA) when charge is complete with VCC in UVLO-free range, and high impedance in undervoltage lockout; absolute maximum voltage is -0.3V to 10V. |
| 8 | EN | input | Chip enable terminal: a high level input allows normal operation, and a low level prohibits charging; absolute maximum voltage is -0.3V to 10V. |
| 9 | EPAD | power_in | Exposed pad, ground pin. |
