Overview
The LM5110-2M/NOPB is a dual 5A gate driver produced by Texas Instruments. This device is designed to replace industry-standard gate drivers with improved peak output current and efficiency. It features two independent and identical driver channels, each capable of sourcing 3A and sinking 5A of current. The LM5110-2M/NOPB is particularly notable for its ability to drive MOSFET gates with both positive and negative VGS voltages, thanks to its negative output voltage capability and separate input and output ground pins.

Key Features
- Independently drives two N-Channel MOSFETs with TTL compatible logic inputs.
- Compound CMOS and bipolar outputs reduce output current variation with voltage and temperature.
- 5A sink/3A source current capability per channel.
- Fast propagation times (25 ns typical) and fast rise and fall times (14 ns/12 ns with 2 nF load).
- Negative output voltage capability, allowing the driver outputs to swing from VCC to VEE, which can be negative with respect to IN_REF.
- Undervoltage lockout protection and shutdown input pin for added safety and convenience.
- Option to operate multiple LM5110-2M/NOPB drivers in parallel to double the drive current capability.
