HX37323-S

ZHHXDZ · Gate Drivers · SOP-8

HX37323-S from ZHHXDZ, 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-connect pin (listed as 空引脚 in the datasheet); it has no internal function, and the datasheet notes that unused pins may be tied to VDD or GND in noisy environments.
2 INA input Channel A logic input; logic high is VIH ≥ 2.4V and logic low is VIL ≤ 0.8V, with VIN rated from -10V to VCC+0.3V, and it has an internal pull-up to VCC (tie to VCC if unused).
3 GND power_in Ground reference pin for the driver; the datasheet recommends a short, low-inductance return path and a single-point star ground connection.
4 INB input Channel B logic input; logic high is VIH ≥ 2.4V and logic low is VIL ≤ 0.8V, with VIN rated from -10V to VCC+0.3V, and it has an internal pull-up to VCC (tie to VCC if unused).
5 OUTB output Channel B inverting gate-drive output, sourcing or sinking up to 2A peak to drive the gate of a P- or N-channel MOSFET.
6 VCC power_in Positive supply pin with a recommended operating range of 4.5V to 20V and an absolute maximum of 25V; place low-ESR/ESL bypass capacitors close between VCC and GND.
7 OUTA output Channel A inverting gate-drive output, sourcing or sinking up to 2A peak to drive the gate of a P- or N-channel MOSFET.
8 NC unconnected No-connect pin (listed as 空引脚 in the datasheet); it has no internal function, and the datasheet notes that unused pins may be tied to VDD or GND in noisy environments.

CAD (KiCad official)

  • Symbol: HX37323-S
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOP-8 (KiCad packages3D, STEP)
  • 3D model files: hx37323-s-etched.step / hx37323-s-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); hx37323-s.step / hx37323-s.glb are the bare package body.
