BQ34Z100PWR-G1 from Texas Instruments, in a TSSOP-14. 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	P2	output	LED 2 drive (multi-LED display mode) or unused. Tie to VSS when not driving an LED.
2	VEN	output	Active-high voltage translation enable output. Optionally switches the external BAT-divider on/off (typ 45 uA saved) when driving a series N-FET. Leave floating or tie to VSS if unused.
3	P1	output	LED 1 drive; also used to drive the single LED in single-LED mode via an N-FET. Tie to VSS when not driving an LED.
4	BAT	input	Translated battery-voltage sense input from the external resistor divider. VBAT abs-max 5.5 V; ADC input range VSS-0.125 V to 5 V.
5	CE	input	Chip Enable. Driving low disconnects the internal LDO from REGIN to place the device in shutdown.
6	REGIN	power_in	Internal LDO regulator input, 2.45 V to 5.5 V (abs-max). Decouple with a 0.1-uF X5R ceramic to VSS.
7	REG25	power_out	2.5-V (typ) output of the internal LDO, also the internal VCC rail. Decouple with a 1-uF (0.47-uF min) ceramic capacitor to VSS.
8	VSS	power_in	Device ground reference.
9	SRP	input	Coulomb-counter positive analog input (nearest BAT-). Connects across the pack sense resistor with SRN; input range VSS-0.125 V to 0.125 V.
10	SRN	input	Coulomb-counter negative analog input (nearest PACK-). Connects across the pack sense resistor with SRP; input range VSS-0.125 V to 0.125 V.
11	P6/TS	input	Pack thermistor sense input; use a 103AT-type (10 kOhm at 25 degC) NTC. Input range VSS-0.05 V to 1 V.
12	P5/HDQ	bidirectional	Open-drain HDQ single-wire slave communication line. Leave floating or tie to VSS if unused. Also usable as GPIO P5.
13	P4/SCL	input	I2C-compatible slave serial clock input; use a 10-kOhm (typ) pull-up to VCC. Also functions as LED 4 drive in four-LED mode, or GPIO P4. Leave floating or tie to VSS if unused.
14	P3/SDA	bidirectional	Open-drain I2C-compatible slave serial data line; use a 10-kOhm (typ) pull-up to VCC. Also functions as LED 3 drive in four-LED mode, or GPIO P3. Leave floating or tie to VSS if unused.

CAD (KiCad official)

3D model: TSSOP-14 (KiCad packages3D, STEP)

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`bq34z100pwr-g1.step`	194 KB	You want the bare part, or you mark your own boards.
`bq34z100pwr-g1-etched.step`	3.0 MB	You want the part with `BQ34Z100PWR-G1` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 759 faces against 237 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.
