Product details

Half-bridge driver for N-channel MOSFETs — what it is and where it fits

The Texas Instruments LM5109AMA/NOPB is a half-bridge gate driver IC for two N-channel MOSFETs. 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

The LM5109AMA/NOPB is listed as Active and ROHS3 compliant. No end-of-life notice, no last-time-buy window. That means you can qualify it into a new BOM without worrying about a forced redesign mid-production.

Frequently asked questions

What is the LM5109AMA/NOPB?

Identifies the part as a half-bridge gate driver, its manufacturer (TI), and basic function for first-time buyers.

Where can I buy LM5109AMA/NOPB?

Directly drives purchase decisions; buyers need reliable sources with stock.

What is the pinout of LM5109AMA/NOPB?
