The MAX22211-EVKIT provides a proven design to evaluate the +36V, 3.8A Dual H-Bridge MAX22211 motor driver. The MAX22211 can drive two brushed DC motors or a single stepper motor. The MAX22211 IC integrates very low impedance FETs in a dual H-Bridge configuration with a typical RON (highside + low-side) of 0,25Ω. The MAX22211-EVKIT features headers, test points, and terminal blocks to provide an interface to the MAX22211 motor driver. The MAX22211 integrated current-sense output ISENA and ISENB can be monitored using test points or can be connected to an external ADC using header J4. The MAX22211 features embedded current-drive regulation (CDR) with adjustable chopping current (ITRIP). The MAX22211-EVKIT operates from an input voltage of +4.5V to +36V (VM). An on board +3.3V regulator U2 (MAX6765TTSD2+) provides a regulated +3.3V to drive the MAX22211 logic inputs. Terminal blocks J1 and J6 are installed to provide an interface for the high voltage, high current VM inputs, and motor driver outputs OUT_A and OUT_B.
