Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The MAX22204AUU is a two-phase stepper motor driver. It integrates two 65V, 3.8AMAX H Bridges. The impedance of the H-bridge FETs is very low, resulting in high drive efficiency and little heat dissipation. The typical value of total RON (high side + low side) is 0.3Ω. The MAX22204AUU integrates a precision current drive regulation circuit and a 128-microstep built-in divider controlled by the STEP/DIR interface. High microstep resolution and advanced control technology ensure smooth and quiet operation.

The MAX22204AUU has the following features:

The voltage rating of the two H Bridges is +65V

Total Rdson (high side + low side) : 300mΩ (typical) (TA = 25°C)

Current rating for each H-bridge (typical for TA = 25°C) :

IMAX = 3.8AMAX (Pulse current driving capacitive load)

IFS(MAX) = 2.8A (maximum full scale current setting for internal current drive regulation)

IRMS = 2ARMS/ phase (TA = 25°C, VM = +24V)

Integrated current control

Full scale DAC current can be configured using external resistors

The torque can be quickly changed between the two levels with a single logic input (TRQ)

Improves efficiency by providing internal current detection (ICS) without the need for larger external resistors

Built-in control via 128 microstep divider

STEP/DIR interface

Integrate DAC and timing controller for microstep function

Multiple attenuation modes (slow, mixed, adaptive)

An external resistor configuration can be used to fix the shutdown time

Current detection output (ISENA, ISENB) Current monitor

Active low level FAULT indicator pin

Protection function

Overcurrent protection for each channel (OCP)

Undervoltage Protection (UVLO)

Thermal shutdown TJ = 155°C (TSD)

Available in TSSOP38 4.4mm x 9.7mm package

• 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.

• 2.Are all our products genuine?

  A: our self-supporting products are from cooperative domestic and foreign original factories or authorized agents, and the source can be traced to ensure the original and authentic products.

• 3.Can you provide the qualification certificate of the original factory or agent?

  A: at present, our self-employed brands TI，ST，ADI，NXP，LATTICE，CYPRESS，INFINEON，XILINX and other first-line brands. Other channels are the original factory and agency channels. If necessary, we can communicate and confirm according to the specific brand and model.

• 4.Can I make an inquiry through the company's website?

  A: You can inquire through the website, or by phone and email.

• 5.When can I deliver the goods after placing an order? How long will it take to get there?

  A: the delivery date is marked in most commodity information. You can estimate the delivery time of the commodity according to the delivery date. The specific arrival time depends on the warehouse where the commodity is located and the logistics mode you choose.

• 6.Can the company issue an invoice?

  A: you can issue ordinary invoices for individual users or special VAT invoices for enterprise users.
