FAN7842MX

onsemi · Gate Drivers · SOP-8

FAN7842MX from onsemi, 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 VCC power_in Low-side and logic supply voltage, specified at 10 V to 20 V with absolute maximum -0.3 V to 25 V.
2 HIN input Logic input for the high-side gate driver output, TTL compatible with VIH 2.9 V minimum and VIL 0.8 V maximum.
3 LIN input Logic input for the low-side gate driver output, TTL compatible with VIH 2.9 V minimum and VIL 0.8 V maximum.
4 COM power_in Logic ground and low-side driver return, with a recommended range of COM to VCC.
5 LO output Low-side driver output, swinging between COM and VCC under recommended operating conditions.
6 VS power_in High-voltage floating supply return, with allowable offset up to 200 V and a negative swing to -9.8 V (typical) for signal propagation at VCC=VBS=15 V.
7 HO output High-side driver output, referenced to VS and swinging between VS and VB.
8 VB power_in High-side floating supply, specified at VS+10 V to VS+20 V with absolute maximum up to 225 V.

CAD (KiCad official)

  • Symbol: FAN7842MX
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOP-8 (KiCad packages3D, STEP)
  • 3D model files: fan7842mx-etched.step / fan7842mx-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); fan7842mx.step / fan7842mx.glb are the bare package body.
