HY2116-DB6B from HYCON Tech, in a SOT-23-6. 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	OD	output	Discharge-control N-MOSFET gate drive output. Drives the gate of the external discharge-control MOSFET (M1). Output-high level V_DH = VDD-0.02V typ; output-low level V_DL = 0.1V typ. Pulled low to disable discharge on overdischarge or discharge overcurrent / load short.
2	CS	input	Overcurrent detection input and charger detection terminal. Senses the voltage drop across the series MOSFETs (M1+M2) via a 2kΩ resistor for discharge-overcurrent (V_DIP=150mV), load-short-circuit (V_SIP=0.85V typ), and charge-overcurrent (V_CIP=-225mV) detection. High-voltage tolerant (absolute max V_CS = VDD-20 to VDD+0.3V, rated to 20V for charger connection).
3	OC	output	Charge-control N-MOSFET gate drive output. Drives the gate of the external charge-control MOSFET (M2). Output-high level V_CH = VDD-0.02V typ; output-low level V_CL = 0.1V typ. Pulled low to disable charging on overcharge or charge overcurrent. Pin is high-voltage tolerant (absolute max V_OC = VDD-20 to VDD+0.3V).
4	NC	unconnected	No internal connection. Leave floating or tie to any potential per PCB layout requirements.
5	VDD	power_in	Positive supply / battery positive terminal input. Connect to Li-ion cell positive through a 100Ω current-limit / ESD resistor (R1) with a 0.1µF bypass cap (C1) to VSS. Operating voltage V_DSOP1 = 1.5V to 8V (abs max VSS-0.3 to VSS+10V). Typical operating current I_DD = 3.0µA at V_DD=3.9V.
6	VSS	power_in	Ground / negative supply input. Connects to the battery negative terminal (and thus to the source of the discharge MOSFET on the low side of the pack).

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`hy2116-db6b.step`	97 KB	You want the bare part, or you mark your own boards.
`hy2116-db6b-etched.step`	1.9 MB	You want the part with `HY2116-DB6B` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 488 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.
