Maxim Integrated MAX22203 Evaluation Kit Half-Bridge Driver for MAX22203 Motor Driver for DC Motors or Single Stepper

The Maxim Integrated e MAX22203 evaluation kit (EV kit) provides a proven design to evaluate the 65V, 3.8A dual H-bridge MAX22203 motor driver. The MAX22203 can drive two brushed DC motors or single stepper motor. The MAX22203 IC integrates very low impedance FETs in a dual H-Bridge configuration with a typical RON (high side + low side) of 0.3Ω. The EV kit features headers, test points, and terminal blocks to provide an interface to the MAX22203 motor driver. The MAX22203 integrated current-sense output ISENA and ISENB can be monitored using test points or can be connected to an external ADC using header J4.
