BCT4054DEUK-TR from BROADCHIP, in a SOT-23-5. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | CHRG | tri_state | Open-drain charging status indicator internally pulled low during charging, in high-impedance state for all other conditions |
| 2 | GND | power_in | Ground connection |
| 3 | BAT | power_out | Battery charging connection pin with fixed charging termination voltage of 4.35V for BCT4054D variant |
| 4 | VCC | power_in | Power supply input pin; chip enters sleep mode when supply voltage falls within 80mV of BAT voltage with battery leakage current reduced to 2μA |
| 5 | PROG | input | Constant current setting and charging current monitoring pin; charging current set via external resistor RPROG to ground with formula IBAT = 1100 × VPROG / RPROG |
