The inverting input means a logic high on the input pulls the gate low. That's the opposite of a non-inverting driver — if your controller outputs active-high PWM, you'll need to invert the signal in firmware or add a logic inverter.
The LM5110-2MX/NOPB is specified for N-channel MOSFETs with a low-side driven configuration. The 5 A sink peak and 14 V maximum supply are within the range needed for many IGBT modules, but the inverting input and independent channel architecture may not suit every IGBT gate drive requirement. For SiC MOSFETs, the 14 V supply maximum is below the typical 18–20 V bias used for SiC drivers — check the specific SiC device's gate drive voltage range before fitting this part.
Typical rise time is 14 ns and fall time is 12 ns. These are typical values at a specified load capacitance — actual edge rates scale with the gate charge of the driven MOSFET.
The LM5106MM/NOPB is a half-bridge driver with non-inverting input and synchronous channel type, rated for 1.2 A peak output and 8 V supply typical. It is not a direct pin-compatible replacement — the LM5110-2MX/NOPB offers higher peak current (3 A / 5 A) and independent low-side channels. For a drop-in second source, verify the pinout and logic polarity against your layout.
No — the driven configuration is low-side only. The LM5110-2MX/NOPB drives the gate referenced to ground, not to a floating bootstrap supply. For high-side drive, look at a half-bridge or high-side driver such as the LM5106.
