产品详情

The MAX22212 evaluation kit (EV kit) provides a proven design to evaluate the +36V, 7.6A single H-bridge MAX22212 motor driver. The MAX22212 drives a single brushed DC motor. The MAX22212 IC integrates very low impedance FETs in a single H-bridge configuration with a typical RON (high-side + low-side) of 0.125Ω. The EV kit features headers, test points, and terminal blocks to provide an interface to the MAX22212 motor driver. The MAX22212’s integrated current sense output ISENA and ISENB can be monitored using test points or connected to an external ADC using header J4. The MAX22212 features embedded current drive regulation (CDR) with adjustable chopping current (IFS) and adjustable current limit off time (tOFF). The MAX22212 EV kit 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 MAX22212 logic inputs. Terminal blocks J1 and J5 are installed to provide an interface for the high voltage, high current VM inputs, and motor driver outputs OUT1_ and OUT2_.
