Package: TQFN-38

Type: Motor Drivers

Description: 65V Single-Channel Brushed Motor Driver 38-TQFN (5x7)

Product Overviews

MAX22203ATU is a dual 65V, 3.8AMAX H-Bridge with PWM inputs and accurate Current Drive Regulation (CDR). 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 MAX22203 can be used to drive two Brushed DC motors or a single Stepper Motor.
