BQ32002DR from Texas Instruments, in a SOIC-8. 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 | OSCI | input | Oscillator input. Connect one terminal of the 32.768-kHz crystal here (CL = 12 pF, Rs up to 70 kOhm). |
| 2 | OSCO | output | Oscillator output. Connect the other terminal of the 32.768-kHz crystal here. |
| 3 | VBACK | power_in | Backup device power input. Connect to a capacitor or non-rechargeable battery. Switchover threshold is 1.8 V (operating->backup) and 2.4 V (backup->operating). |
| 4 | GND | power_in | Ground reference for the device. |
| 5 | SDA | bidirectional | I2C serial data line. Open-drain; requires an external pull-up to VCC (typ. 4.7 kOhm). Supports standard mode (100 kHz) and fast mode (400 kHz). |
| 6 | SCL | input | I2C serial interface clock input. Requires an external pull-up to VCC (typ. 4.7 kOhm). Supports up to 400 kHz. |
| 7 | IRQ | output | Configurable interrupt/frequency test output. Open-drain, requires external pull-up to VCC (typ. 4.7 kOhm). Configurable via FT/FTF/OUT bits as 1 Hz, 512 Hz, or static level. Must be tied to VCC when unused to prevent IRQ operation on backup supply. |
| 8 | VCC | power_in | Main device power supply, 3.0 to 3.6 V nominal (absolute max 4 V). Place a 1 uF decoupling capacitor near the pin. ICC typ. 65 uA, max 200 uA. |
