4061H from HL, in a SOT23-6. 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 | CHRG | output | Open-drain charge-status output that is pulled low while charging and goes high-impedance otherwise, with V_OL of 0.5 V max at 5 mA sink. |
| 2 | GND | power_in | Ground reference pin for the charger, also the return point for the PROG programming resistor R_PROG. |
| 3 | BAT | bidirectional | Battery connection that supplies charge current and sets the 4.2 V float voltage (4.35 V customizable), with an absolute maximum of 12 V and 600 mA BAT pin current. |
| 4 | VCC | power_in | Positive input supply, operating from 5 V with an absolute maximum of 28 V, and internal OVP stops charging above 6.5 V. |
| 5 | STDBY | output | Open-drain battery-full status output that is pulled low when charge termination is complete, with V_OL of 0.5 V max at 5 mA sink. |
| 6 | PROG | passive | Constant-charge-current program pin where R_PROG to GND sets I_BAT (for example 2 kΩ gives 450 mA), regulated to 1.0 V nominal, and it is monitored for C/10 termination at 100 mV. |
