Product details

Dual low-side driver for N-channel MOSFETs

Supply voltage spans 3.5V to 14V, covering both 5V and 12V gate drive rails common in industrial and automotive power stages.

The 3A source / 5A sink peak current rating is the headline spec for this driver. It determines how quickly the gate of a large N-channel MOSFET can be charged and discharged, directly impacting switching losses and dead-time requirements. With 14ns rise and 12ns fall times, the LM5110-1M/NOPB can drive moderate-to-large MOSFET gates at switching frequencies up to several hundred kilohertz without excessive cross-conduction or shoot-through. The asymmetric sink-to-source ratio (5A vs 3A) is typical for low-side drivers — faster turn-off reduces the Miller plateau duration and improves efficiency in hard-switching topologies.

The NOPB suffix indicates ROHS3 compliance (lead-free). For a BOM freeze or production ramp, the active lifecycle removes the last-time-buy risk that haunts NRND or EOL parts.

Frequently asked questions

How does LM5110-1M/NOPB compare to the LM5110-2M variant?

The LM5110-1M and LM5110-2M share the same pinout, package, and drive strength. The key difference is the input polarity: the -1M is non-inverting, the -2M is inverting. Choose based on whether your PWM controller output is active-high or active-low.

Can LM5110-1M/NOPB be used for driving IGBTs in motor control?

Yes, the 3A source / 5A sink peak current and 14ns/12ns rise/fall times are adequate for driving small-to-medium IGBTs in motor-drive applications at switching frequencies up to several tens of kilohertz. For larger IGBT modules with higher gate charge, a driver with higher peak current (e.g., 9A or more) would be a better fit.

Is LM5110-1M/NOPB a direct drop-in replacement for the LM5110-1M (non-NOPB)?

Yes, the LM5110-1M/NOPB is the lead-free (ROHS3) version of the original LM5110-1M. Electrical specifications, pinout, and package are identical. The NOPB suffix simply indicates compliance with the ROHS directive — no other functional difference.
