1 Introduction

The LM2105 is designed to primarily evaluate the LM2105 performance. This driver is a 105-V boot voltage, high-side, low-side driver with 0.5-A peak source and 0.8-A sink current for driving two N-channel MOSFETs. The same board can be used to evaluate other pin-to-pin compatible parts in the supported package. The LM2105 has low propagation delay and low propagation delay matching between the high- and low-side rising and falling edges of the driver outputs for reliable timing of the gate-drive signals.
