ANALOG DEVICES MAX22910EVKIT# Evaluation Board, MAX22910, 80V, High Side Switch

MAX22910EVKIT# is a MAX22910 evaluation kit (EV kit). It provides a proven design to evaluate the MAX22910, a 21mohm single-channel high-side switch with advanced diagnostics for industrial applications. The EV kit is powered from an external power supply at VDD, while the on-board LT3014 LDO generates a 3.3V for the logic input level of the MAX22910. The logic level can be set with an external power supply at VL, alternatively. The EV kit is preinstalled with ADuM342E0, a four-channel digital isolator with default-low output. It provides digital isolation between the field and logic sides for logic control I/Os. The MAX22910 EV kit comes with an output clamping diode installed to protect the device from negative kickback voltage during switching off the inductive loads. It is specified for EMC protection against surge and ESD transients, EFT, and RF conducted immunity. The MAX22910 EV kit comes with MAX22910AFZ+ installed in a compact 4.5mm x 5.75mm FC2QFN package.
