HT2810AREZ from HTCSEMI, 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 NTC temperature sense input; charging is suspended if TEMP is below 45% or above 80% of the input voltage, and leaving TEMP floating or grounded disables the temperature function while other charging functions continue. |
| 2 | PROG | passive | Sets the constant-charge current through a 1% resistor to ground and monitors charge current, with the pin fixed at 0.05V in short charge, 0.1V in trickle charge and 1V in constant current, and I_BAT = (V_PROG / R_PROG) × 1000. |
| 3 | GND | power_in | Chip ground, to be connected to the exposed thermal pad and a large copper plane. |
| 4 | VCC | power_in | Power input pin, recommended operating range 4 V to 6 V with absolute maximum -0.3 V to 24 V to GND; bypass close to VCC and GND with at least 10 µF effective ceramic capacitance. |
| 5 | BAT | power_out | Battery charge output connected to the battery positive terminal, requiring at least 10 µF effective ceramic capacitor to ground; absolute maximum voltage to GND is -0.3 V to 6 V. |
| 6 | DONE | output | Full-charge indicator open-drain output connected to the LED cathode, pulled low when the battery is fully charged; absolute maximum voltage to GND is -0.3 V to 24 V. |
| 7 | CHRG | output | Charge-status indicator open-drain output connected to the LED cathode, pulled low while charging; absolute maximum voltage to GND is -0.3 V to 24 V. |
| 8 | CE | input | Enable input where high enables charging and low disables it, with CE rising high-level threshold 1.37 V and falling low-level threshold 1.16 V; absolute maximum voltage to GND is -0.3 V to 24 V. |
| 9 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
