Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The MAX20444CATG/VY+ is a 4-channel backlighting driver with boost controller for automotive displays. The integrated current outputs support up to 130mA of LED suction current per channel. The device supports a wide input voltage range of 4.5V to 36V and can withstand automotive throw-load events.

The internal current-mode switching DC-DC controller supports either boost or SEPIC circuits and operates in the 400kHz to 2.2MHz frequency range. The integrated spread spectrum helps to reduce EMI and the adaptive output voltage control minimises power consumption in the LED current drive path.

The device features I22C controlled pulse width modulation (PWM) dimming and hybrid dimming, with a minimum pulse width of 500ns in any case.

Comprehensive diagnostic information is also provided via the I2C interface, while standalone operation is also supported.

The MAX20444CATG/VY+ is available in a 24-pin, TQFN or 24-pin, side-moisture-proof TQFN (SWTQFN) package and operates over the -40°C to +125°C temperature range.

• 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.
