Half-bridge gate driver for N-channel MOSFETs
The Texas Instruments LM5106MM/NOPB is a half-bridge gate driver designed to drive two N-channel MOSFETs in a synchronous configuration. It accepts a non-inverting input and operates from an 8 V to 14 V supply, with a bootstrap high-side voltage rating up to 118 V. The driver delivers 1.2 A peak source and 1.8 A peak sink current, with typical 15 ns rise and 10 ns fall times. It comes in a 10-VSSOP surface-mount package and is rated for -40°C to 125°C junction temperature, making it suitable for industrial power supplies, motor drives, and DC-DC converters.
Gate drive strength and switching speed
With 1.2 A source and 1.8 A sink peak current, the LM5106MM/NOPB can charge and discharge the gate capacitance of medium-power MOSFETs quickly. The 15 ns rise and 10 ns fall times (typical) keep switching losses low.
Package and thermal environment
The 10-VSSOP package (3.00 mm width) is a compact footprint for space-constrained boards. The -40°C to 125°C junction temperature range covers industrial and automotive under-hood environments. Surface-mount assembly aligns with standard reflow profiles; the tape-and-reel option supports volume pick-and-place.
Sourcing and lifecycle
The LM5106MM/NOPB is listed as Active in production and RoHS3 compliant. It is a current-design-in part with no end-of-life notice. Sourced through independent distribution; availability and current pricing are confirmed at quote time against an RFQ.
