Product details

It delivers 1A peak source and 1A peak sink current, with independent non-inverting inputs.

1 A peak drive — what it means for your MOSFET selection

The 1 A peak source and sink current sets the gate-drive strength. The 15 ns rise and fall times keep switching losses manageable.

Package and mounting — 8-SOIC, surface-mount only

The LM5109AMA/NOPB comes in an 8-SOIC package, surface-mount. The Tube shipping medium means it arrives in a stick.

Lifecycle and sourcing — active, no LTB risk

No end-of-life notice, no last-time-buy window.
