HY2120-AB
HYCON Tech · Battery Management · SOT-23-6
HY2120-AB from HYCON Tech, in a SOT-23-6. 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 | OD | output | MOSFET gate connection pin for discharge control; the OD output voltage is rated VSS-0.3 V to VDD+0.3 V. |
| 2 | OC | output | MOSFET gate connection pin for charge control; the OC output voltage is rated VDD-33 V to VDD+0.3 V. |
| 3 | CS | input | Input pin for current sense and charger detect; the CS input voltage is rated VDD-33 V to VDD+0.3 V. |
| 4 | VC | input | Input pin for the center voltage between the two cells; the connection example uses a series resistor R2 of 100 Ω to 470 Ω (330 Ω typ.) to limit current and strengthen ESD protection. |
| 5 | VDD | power_in | Power supply pin; the operating voltage between VDD and VSS is 1.5 V to 10 V, with an absolute maximum of VSS-0.3 V to VSS+10 V. |
| 6 | VSS | power_in | Ground pin, the reference point (0 V) for all voltages in the datasheet. |
