Specifications

Operating Supply Voltage: 4.5 V to 65 V

Output Current: 3.8 A

Operating Supply Current: 5 mA

Minimum Operating Temperature: - 40 C

Maximum Operating Temperature: + 125 C

Product Description

MAX22204ATU+ is a two-phase stepper motor driver. It integrates two 65V, 3.8AMAX H-Bridges. The H-Bridge FETs have very low impedance, resulting in high driving efficiency and minimal heat.

Features

Two H-Bridges with +65V Voltage Rating

Total Rdson (High-Side + Low-Side): 300mΩ Typical (TA = 25°C)

Current Ratings per H-Bridge (Typical at TA = 25°C)

IMAX = 3.8AMAX (Impulsive Current for Driving Capacitive Loads)

IRMS = 2ARMS per Phase (TA = 25°C, VM = +24V)

Full-Scale DAC Current Configurable with External Resistance

One Logic Input (TRQ) to Quickly Change the Torque among Two Levels

• 1.Is the inventory and price seen on the platform accurate?

  A: all online goods on the shelves can be ordered online, but considering the large liquidity of spot inventory, it is not possible to achieve 100% accuracy at present. In case of any abnormality, you can contact our company online and give the corresponding solution.
