BQ32002DR

Texas Instruments · Real-time Clocks (RTC) · SOIC-8

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.

  • 3D model: SOIC-8 (KiCad packages3D, STEP)
  • 3D model files: bq32002dr-etched.step / bq32002dr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); bq32002dr.step / bq32002dr.glb are the bare package body.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: Texas Instruments datasheet (30 pp, sha256 8f78331d8f0834e7, retrieved 2026-08-17, tier: manufacturer)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
