Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The LTC4420CDD is a dual-input monolithic PowerPath™ Prioritiser with low operating current that provides backup switching to keep critical circuits functioning in the event of power drops and brownouts. Unlike diode-OR products, there is virtually no current draw from the passive power supply, even if the inactive power supply has a higher voltage than the diode-OR. Internal 2Ω current-limited PMOS switches provide a choice of power paths from the main input (V1) or backup input (V2) to the output. Two adjustable voltage monitors are set via an external resistor divider for flexible V1 to V2 switching and V2 undervoltage thresholds.V1 is continuously monitored while V2 is power-monitoredThe ADJ monitor switches OUT to V2 when the main input, V1, drops.It is disconnected from OUT if V2DIS is zero when V2 drops.The ADJ monitor is also disconnected from OUT when V2 drops.The ADJ monitor is also disconnected from the OUT when V1 drops.The ADJ monitor is also disconnected from the OUT when V1 drops.

Applications

● Low Power Battery Backup

● Portable devices

● Point-of-Sale (POS) devices

• 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.
