Evaluates: MAX22201

MAX22201 Evaluation Kit

General Description

The MAX22201 evaluation kit (EV kit) provides a proven

design to evaluate the MAX22201 brushed DC motor

driver. The MAX22201 IC integrates very low impedance

FETs in a full bridge configuration for use in 36V, 3.5A

motor driver applications. The typical RON (high side +

low side) of this configuration is 0.3Ω. The EV kit features

headers, test points, and terminal blocks to provide an

interface to the MAX22201 motor driver PWM inputs, cur-

rent sense outputs, and power supply inputs and motor

driver outputs. An on-board ICM7556 provides an on-

board PWM generator with a fixed frequency of 16.5kHz

and an adjustable duty cycle from 4% to 95%. The EV kit

also allows the user to adjust the integrated current limit-

ing using an on-board potentiometer.
