Page 2: Introduction
All trademarks are the property of their respective owners. Introduction The LM5108EVM is designed to primarily evaluate the LM5108 performance. This driver is a 100-V boot voltage, high-side, low-side driver with 1.5-A peak source and 2.5-A sink current for driving two N-Channel MOSFETs. -
Page 3: I/O Description
CAUTION The LM5108EVM is designed for low-voltage evaluation only, and is not certified for evaluation with voltages beyond the absolute maximums listed in the electrical specifications. Do not evaluate high-voltage parameters with this board. -
