TCAN1051HDRBTQ1

Texas Instruments · CAN ICs · HVSON-8-EP(3x3)

TCAN1051HDRBTQ1 from Texas Instruments, in a HVSON-8-EP(3x3). Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 TXD input CAN transmit data input; LOW for dominant and HIGH for recessive bus states.
2 GND power_in Ground connection; for DRB (VSON) packages the thermal pad may be connected to GND to optimize thermal characteristics.
3 VCC power_in Transceiver 5-V supply voltage; the datasheet recommends operation from 4.5 V to 5.5 V with a 4.7 µF bulk and 0.1 µF bypass capacitor close to the pin.
4 RXD output CAN receive data output, LOW for dominant and HIGH for recessive bus states; receiver output current is limited to ±8 mA (absolute maximum).
5 NC unconnected No connect on H-suffix devices (VIO level-shifting pin is only present on V-suffix devices); may be left floating or tied to an existing net.
6 CANL bidirectional Low-level CAN bus input/output line; bus pins withstand -70 V to 70 V on H-suffix devices.
7 CANH bidirectional High-level CAN bus input/output line; bus pins withstand -70 V to 70 V on H-suffix devices.
8 S input Silent Mode control input, active high.
9 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).

  • 3D model: HVSON-8-EP(3x3), generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 0.9 mm nominal VQFN height). Neither the vendor nor KiCad ships a 3D model for this package, so the dimensions are nominal, not the manufacturer's CAD (STEP)
  • 3D model files: tcan1051hdrbtq1-etched.step / tcan1051hdrbtq1-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tcan1051hdrbtq1.step / tcan1051hdrbtq1.glb are the bare package body.
