Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The LT8672EMS is an active rectifier controller for reverse input protection. It drives an external N-channel MOSFET in place of a power Schottky diode. Its very low quiescent current and fast transient response meet the demanding requirements of automotive applications with AC input signals up to 100kHz. The signal is rectified and the external FETs minimise power dissipation, simplifying thermal management on the PCB. With a voltage drop of only 20mV, the solution simplifies the minimum input voltage requirement for cold start.

Characteristics

● Reverse input protection to -40V

● Improved performance compared to Schottky diodes:

● Power consumption reduction of >90%

● Reduced voltage drop to 20mV

● Ultra-fast transient response:

● Rectified 6VP-P (up to 50kHz)

● Rectified 2VP-P (up to 100kHz)

● Wide operating voltage range: 3V to 42V

● Low quiescent current (during operation): 20µA

● Low shutdown current: 3.5µA

● Precise enable pin threshold: 1.21V

● Compliant with AEC-Q100 for automotive applications

● Small 10-pin MSOP package, 10-pin 3mm × 2mm DFN package, and 3mm × 2mm side-wettable DFN package

Applications

● Automotive battery protection

● Industrial power supplies

● Portable instrumentation

• 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.
