LM5109AMAX-JSM

JSMSEMI · Gate Drivers · SOP-8

LM5109AMAX-JSM from JSMSEMI, 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 supply voltage; recommended 6 V to 20 V, absolute maximum 25 V.
2 HIN input High-side logic signal input; recommended 0 V to VCC, compatible with 3.3 V, 5 V and 15 V logic.
3 LIN input Low-side logic signal input; recommended 0 V to VCC, compatible with 3.3 V, 5 V and 15 V logic.
4 VSS power_in Ground reference for the device; all voltage ratings are referenced to VSS.
5 LO output Low-side gate drive output; 0 V to VCC, 1.2 A source / 1.5 A sink capability.
6 VS power_in High-side floating ground (return); recommended -9 V to 250 V.
7 HO output High-side gate drive output; recommended VS to VB.
8 VB power_in High-side floating supply; recommended VS+6 V to VS+20 V, absolute maximum 275 V.
