BL5612

BL(Shanghai Belling) · Gate Drive ICs · SOP-8

BL5612 from BL(Shanghai Belling), in a SOP-8. 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 NC unconnected No connection; the datasheet lists this pin as not connected.
2 INA input Logic input INA controls the H-bridge; the recommended input logic range is 0 to 5.0 V.
3 INB input Logic input INB controls the H-bridge; the recommended input logic range is 0 to 5.0 V.
4 NC unconnected No connection; the datasheet lists this pin as not connected.
5 GND power_in Ground reference for the device.
6 OUTB output H-bridge output B, driving the motor terminal; it is high-impedance in stop mode and low in brake mode.
7 OUTA output H-bridge output A, driving the motor terminal; the datasheet calls for a 0.1uF capacitor between OUTA and OUTB across the motor.
8 VM power_in Motor/H-bridge supply, recommended 3.0 V to 25.0 V with an absolute maximum of 30.0 V; the datasheet calls for a 10uF or larger capacitor to GND.

CAD (KiCad official)

  • Symbol: BL5612
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOP-8 (KiCad packages3D, STEP)
  • 3D model files: bl5612-etched.step / bl5612-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); bl5612.step / bl5612.glb are the bare package body.
