Product details

Half-bridge gate driver for N-channel MOSFETs

It delivers a peak output current of 3A for both source and sink, which means it can charge and discharge the gate capacitance of medium-power MOSFETs quickly, reducing switching losses in a 9V to 14V supply rail. The independent channel architecture lets the high-side and low-side drivers operate with separate timing, useful for dead-time control in synchronous buck converters or full-bridge topologies.

Thermal and package considerations for layout

Bootstrap supply and high-side voltage headroom

The high-side driver uses a bootstrap supply, with a maximum bootstrap voltage of 118 V. This sets the ceiling for the DC bus voltage in the half-bridge.

It is ROHS3 compliant. There is no LTB risk, and the part remains eligible for new designs.

Frequently asked questions

Is LM5101AMR/NOPB obsolete or end-of-life?

No, the LM5101AMR/NOPB is listed as Active in production from Texas Instruments, with no end-of-life status. It is still available for new designs and production runs.

Can LM5101AMR/NOPB drive two MOSFETs in a half-bridge?

Yes, the LM5101AMR/NOPB is a half-bridge gate driver with two independent channels, each capable of sourcing and sinking 3A peak current, designed to drive two N-channel MOSFETs in a half-bridge configuration.
