Low-side gate driver for N-channel MOSFETs
The Texas Instruments LM5111-3MX/NOPB is a dual-channel low-side gate driver designed to drive N-channel MOSFETs, delivering 3 A peak source and 5 A peak sink current per channel. It operates from a 3.5 V to 14 V supply rail, making it suitable for a range of power-conversion and motor-drive gate-drive stages.
Switching performance and logic interface
Typical rise and fall times of 14 ns and 12 ns respectively allow fast switching transitions, reducing switching losses in the external MOSFETs. The driver accepts both inverting and non-inverting input signals on independent channels, giving flexibility in half-bridge or dual-switch topologies.
Package and temperature grade
Housed in an 8-SOIC package (0.154" width, 3.90 mm), surface-mount assembly with a standard footprint that suits compact power-stage layouts.
Lifecycle and compliance
The part is ROHS3 compliant, meeting current environmental requirements for lead-free assembly.
