AP5056HSPER from UMW, in a SOP-8-EP. 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	TEMP	input	Battery temperature sense input. Connects to the wiper of an NTC thermistor divider on the battery pack; charging is inhibited when the pin voltage is outside the safe window (over-temperature / under-temperature protection).
2	PROG	passive	Charge-current program pin. An external resistor RPROG from PROG to GND sets the fast-charge current (RPROG=2k -> 500 mA typ; RPROG=1k -> 1000 mA typ). Also serves as a current-monitor output; VPROG is typ 1 V during current-mode charging.
3	GND	power_in	Device ground / VSS reference. All voltages are referenced to this pin.
4	VCC	power_in	Input supply from USB / adapter. Working range 4.25-5.5 V, absolute max 30 V, with input OVP tripping at typ 6.5 V. A ~10 uF bypass capacitor to GND is recommended.
5	BAT	power_out	Charge current output to the Li-ion cell. Regulates to a preset 4.2 V float voltage (4.16-4.24 V) and sources up to ~1.4 A absolute max. A ~10 uF capacitor to GND is recommended for stability.
6	STDBY	output	Standby / charge-complete status, open-drain, active-low. Pulls low (Vol <= 0.5 V at 5 mA) when charging has terminated (input present but cell fully charged); high-Z otherwise. Typically drives an indicator LED to VCC through a series resistor.
7	CHRG	output	Charging status, open-drain, active-low. Pulls low (Vol <= 0.5 V at 5 mA) while a charge cycle is in progress; high-Z during standby or when charging is inhibited. Typically drives an indicator LED to VCC through a series resistor.
8	CE	input	Chip enable input. Drive high (or leave pulled high through ~1 k as in the typical application) to enable charging; drive low to place the device in shutdown (supply current drops to ~180 uA). Absolute max VCE = 5.5 V.
EP	EPAD	power_in	Exposed thermal pad on the ESOP-8 package underside. Solder to a copper ground plane for heat dissipation; electrically tie to GND.

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`ap5056hsper.step`	125 KB	You want the bare part, or you mark your own boards.
`ap5056hsper-etched.step`	2.4 MB	You want the part with `AP5056HSPER` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 600 faces against 152 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.
