TCAN1044VDDFR

Texas Instruments · CAN ICs · TSOT-23-8

TCAN1044VDDFR from Texas Instruments, in a TSOT-23-8. 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 TXD input CAN transmit data input from the CAN controller. Integrated pull-up to VIO forces a recessive bus state if the pin is left floating. Referenced to VIO logic levels.
2 GND power_in Device ground reference for both VCC and VIO supplies.
3 VCC power_in 5 V bus-side supply voltage (4.5 V to 5.5 V recommended). Powers the CAN bus driver stage.
4 RXD output CAN receive data output to the CAN controller. Tri-states when device is powered off. Output levels referenced to VIO; IOH = -2 mA, IOL = 2 mA.
5 VIO power_in IO supply voltage for internal level shifter, supporting 1.7 V to 5.5 V logic (1.8 V, 2.5 V, 3.3 V, or 5 V systems). Sets logic thresholds for TXD, RXD, and STB.
6 CANL bidirectional Low-level CAN bus input/output line. Bus fault protected to ±58 V and ISO 7637 pulse tolerant. Connects to the CAN twisted-pair bus.
7 CANH bidirectional High-level CAN bus input/output line. Bus fault protected to ±58 V and ISO 7637 pulse tolerant. Connects to the CAN twisted-pair bus.
8 STB input Standby mode control input. Logic high places the device in low-power standby with wake-up detection; logic low selects normal mode. Integrated pull-up defaults the pin to standby when floating. Referenced to VIO.

Ordering variants

Same part, different packaging or reel option.

  • TCAN1044VDDFR

CAD (KiCad official)

  • Symbol: TCAN1044VDDFR
  • Footprint: Package_TO_SOT_SMD:SOT-23-8
  • 3D model: TSOT-23-8 (KiCad packages3D, STEP)
  • 3D model files: tcan1044vddfr-etched.step / tcan1044vddfr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tcan1044vddfr.step / tcan1044vddfr.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
tcan1044vddfr.step 123 KB You want the bare part, or you mark your own boards.
tcan1044vddfr-etched.step 2.0 MB You want the part with TCAN1044VDDFR already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 536 faces against 147 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.
