AP5054HTCER from Wuxi Chipown Micro electronics, in a SOT-23-6L. 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	output	Open-drain charge status output. Pulled low by an internal N-channel MOSFET while charging; goes high-impedance during undervoltage lockout or upon completion of the charge cycle. Typical low-level output voltage is 1.2V at 1mA (max 1.5V).
2	GND	power_in	Device ground reference.
3	BAT	power_out	Charge current output to the Li-Ion battery. Regulates the final float voltage to 4.2V (4.16-4.24V) and supplies up to ~750mA. An internal precision resistor divider from this pin sets the float voltage and is disconnected in shutdown mode.
4	VCC	power_in	Positive input supply. Operates from 4.25V to 5.5V (absolute range 4.25V-20V with 5.8-6.4V OVP). Bypass with at least a 1uF capacitor. When VCC drops within ~30mV of VBAT the device enters shutdown, dropping IBAT to <2uA.
5	STDBY	output	Open-drain standby/charge-complete status output. Pulled low by an internal switch when the battery charge is complete; otherwise high-impedance. Typical low-level output voltage is 1.2V at 1mA (max 1.5V). Used to drive a 'charge done' indicator (e.g., green LED).
6	PROG	bidirectional	Charge current program, charge current monitor, and shutdown pin. Program charge current with a 1% resistor RPROG to GND: IBAT = (VPROG/RPROG) * 1000. Servos to 0.1V in trickle mode and 1.0V in constant-current mode. Floating RPROG lets an internal 3uA pull-up drive the pin to the 1.21V shutdown threshold, entering shutdown (Icc drops to ~180uA); pin is clamped near 2.4V.

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`ap5054htcer.step`	97 KB	You want the bare part, or you mark your own boards.
`ap5054htcer-etched.step`	1.9 MB	You want the part with `AP5054HTCER` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 491 faces against 117 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.
