Analog Devices / Maxim Integrated MAX22205 High Current Single H-Bridge

Analog Devices MAX22205 High Current Single H-Bridge has a high current 65V, 7.6AMAX H-Bridge to drive one brushed DC motor or one half stepper motor. The H-Bridge FETs feature very low impedance, resulting in high driving efficiency and low heat. The typical total RON (high-side + low-side) is 0.15Ω. The Analog Devices H-Bridge can be PWM controlled by two logic inputs (DINA, DINB). A third Enable (EN) logic input can be used to configure the outputs to high impedance for coasting the motor.
