Description

The 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. The MAX22203 features embedded current-drive regulation (CDR) with adjustable chopping current (ITRIP) and adjustable current-limit off-time (tOFF). The MAX22203 EV kit operates from an input voltage of +4.5V to +65V (VM). An on board +3.3V regulator U2 (MAX6765TTSD2+) provides a regulated +3.3V to drive the MAX22203 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 OUT1_ and OUT2_.
