Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The MAX22291 is a family of 2-channel enhanced, fast, low-power digital galvanic isolators using Maxim's proprietary process technology. All devices feature enhanced isolation and can reach a rated withstand voltage of 3kVRMS in less than 60 seconds. The automotive and general purpose devices are rated for operating ambient temperatures from -40°C to +125°C. Devices with the /V suffix are AEC-Q100 compliant.

- Industrial Grade 

- Isolated SPI 

- Isolated RS-232, RS-485/RS-422, CAN 

- Fieldbus communication 

- Motor drive simplification 

These devices transmit digital signals between circuits with different power domains, using only 0.78mW per channel at 1Mbps (1.8V supply). The low power consumption feature reduces system dissipation, improves reliability and enables compact designs.

These devices have a maximum data rate of 25Mbps or 200Mbps and their outputs are either default high or default low. They feature low propagation delay and low clock jitter to reduce system latency.

Independent 1.71V to 5.5V supplies on each side of the isolator also make the devices suitable for use as level converters.

The MAX22291's two channels transmit data in opposite directions, making the MAX22291 ideal for isolating transceiver Tx and Rx lines.

• 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.
