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. |
