# 4060H

**HL** · Battery Management · SOT23-5

4060H from HL, in a SOT23-5. 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 indicator output that is pulled low while charging and goes high-impedance when charging is finished or in a fault or out-of-temperature state. |
| 2 | GND | power_in | Ground reference pin for the charger; the PROG charge-current resistor is connected between PROG and this pin. |
| 3 | BAT | bidirectional | Battery connection that receives the charge current; the datasheet limits the BAT pin to -0.3V to 12V with a maximum pin current of 600mA. |
| 4 | VCC | power_in | Positive input supply that accepts 5V operation with an absolute maximum of 28V, and the internal OVP stops charging when VCC reaches 6.5V. |
| 5 | PROG | passive | Charge-current programming pin; a resistor to GND sets the constant charge current (e.g. 2K gives 450mA), with 1.0V on the pin in constant-current mode and a maximum pin current of 600uA. |
