Product details

What this low-side driver does and where it fits

The Texas Instruments LM5110-2M/NOPB is a dual low-side gate driver designed to drive N-channel MOSFETs in ground-referenced switching applications. Each of the two independent channels delivers a peak source current of 3 A and a peak sink current of 5 A, with typical rise and fall times of 14 ns and 12 ns respectively — fast enough to minimize switching losses in converters running from 3.5 V to 14 V supply rails. The inverting input logic (VIL at 0.8 V, VIH at 2.2 V) simplifies interface to PWM controllers that use active-low enable or complementary drive. This part is a standard choice for point-of-load regulators, synchronous buck converters, and low-side driver stages in industrial power supplies where the -40°C to 125°C junction temperature rating covers both indoor and outdoor equipment.

3 A source / 5 A sink — what it means for your FET selection

The asymmetry between source and sink current (3 A vs 5 A) is intentional: it pulls the gate down harder than it pushes up, which speeds turn-off relative to turn-on.

Active lifecycle and sourcing posture

TI lists the LM5110-2M/NOPB as Active with ROHS3 compliance. No end-of-life notification or last-time-buy schedule is in effect.

Frequently asked questions

What is the difference between LM5110-2M/NOPB and LM5110-1M/NOPB?

The -2M variant has an inverting input; the -1M variant has a non-inverting input. All other electrical ratings — 3 A source, 5 A sink, 14 ns/12 ns rise/fall, 3.5 V to 14 V supply, -40°C to 125°C — are identical. Choose the input polarity that matches your PWM controller's output logic.

Can LM5110-2M/NOPB replace UCC27424?

Both are dual low-side drivers in SOIC-8, but the UCC27424 is a non-inverting driver with different input thresholds and slightly different timing. The LM5110-2M/NOPB is inverting, so a direct drop-in replacement requires verifying the PWM controller's output polarity and the logic threshold compatibility. Check the input logic levels (VIL 0.8 V, VIH 2.2 V) against the controller's output swing before substituting.
