Analog Devices MAX22203 Evaluation Kit provides a proven design to evaluate the +65V, 3.8A Dual H-Bridge MAX22203 motor driver. The MAX22203 offers two H-bridges with a 65V maximum operating voltage. Each H-Bridge can be controlled individually and has a very low typical RON (high-side + low-side) of 0.3Ω, resulting in high driving efficiency and low heat generation.
The Analog Devices MAX22203 Evaluation Kit operates from an input voltage of +4.5V to +65V (VM). An on-board +3.3V regulator U2 (MAX6765TTSD2+) implements a regulated +3.3V to drive the MAX22203 logic inputs. Terminal blocks J1 and J6 are installed to produce an interface for the high voltage, high current VM inputs, and motor driver outputs OUT1_ and OUT2_.
