Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The MAX22210AUI is a 2-phase stepper motor driver. It integrates two 36V, 3.8AMAX H Bridges. The H-bridge FET has a very low impedance, resulting in high drive efficiency and little heat. The typical value of total RON (high side + low side) is 0.25Ω.

The MAX22210AUI 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 MAX22210AUI has the following features:

The two H Bridges are rated 36V

Total RDS(ON) (HS + LS) : 250 Mω at TA = +25°C (typical)

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

IMAX = 3.8AMAX (Pulse current driving a small capacitive load)

IFS = 3AMAX (full scale current Settings for internal current drive regulation)

IRMS = 2ARMS

Integrated current control

Full scale current can be configured using external resistors

The accuracy of current control for low current values is improved by one logic input (HFS)

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 Dacs and lookup tables for microstep functionality

Multiple attenuation modes (slow, mixed, adaptive)

PWM shut-off times can be configured using external resistors

Current detection output (Current monitoring) (ISENA, ISENB)

FAULT indicator pin

Protection function

Overcurrent protection (OCP) for each power FET

UVLO

Thermal shutdown (TSD) TJ = +165°C

Available in 28-pin, 4.4mm x 9.7mm TSSOP 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.
