BQ34Z100PWR-R2 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 output or unused (connect to VSS). |
| 2 | VEN | output | Active high voltage translation enable output; controls input voltage divider on/off to reduce power consumption (typ 45 µA). |
| 3 | P1 | output | LED 1 output or unused (connect to VSS); can drive single LED with small signal N-FET in series. |
| 4 | BAT | input | Translated battery voltage input; input range 0 V to 5 V (VA2). |
| 5 | CE | input | Chip enable input; internal LDO is disconnected from REGIN when driven low. |
| 6 | REGIN | power_in | Internal LDO input; supply range 2.7 V to 4.5 V for normal operation; decouple with 0.1-µF ceramic capacitor to VSS. |
| 7 | REG25 | power_out | 2.5 V regulated output from internal LDO; decouple with 1-µF ceramic capacitor to VSS; output voltage range 2.3 V to 2.7 V. |
| 8 | VSS | power_in | Device ground connection. |
| 9 | SRP | input | Analog input to coulomb counter; integrate voltage between SRP and SRN where SRP is nearest BAT- connection; input range -0.125 V to +0.125 V. |
| 10 | SRN | input | Analog input to coulomb counter; integrate voltage between SRP and SRN where SRN is nearest PACK- connection; input range -0.125 V to +0.125 V. |
| 11 | P6/TS | input | Pack thermistor voltage sense input; use 103AT-type thermistor; input range 0 V to 1 V. |
| 12 | P5/HDQ | bidirectional | Open-drain HDQ serial communication line (target); if unused, leave floating or tie to VSS. |
| 13 | P4/SCL | input | I2C serial communication clock input; use with 10-kΩ pullup resistor (typical); also used for LED 4 in four-LED mode; if unused, leave floating or tie to VSS. |
| 14 | P3/SDA | bidirectional | Open-drain I2C serial communication data line (target); use with 10-kΩ pullup resistor (typical); also used for LED 3 in four-LED mode; if unused, leave floating or tie to VSS. |
