Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The INA301-Q1 consists of a high common mode current sense amplifier and a high speed comparator that provides overcurrent protection by measuring the voltage across the current sense or shunt resistor and comparing this voltage to a defined threshold limit. The device has an adjustable limiting threshold range which is set by a single external limit setting resistor. The shunt monitor is capable of measuring differential voltage signals over a common mode voltage range of 0V to 36V, independent of the supply voltage. 

The open-drain alarm output can be configured in either transparent mode (where the output state remains the same as the input state) or latch mode (where the alarm output is cleared when the latch is reset). With an alarm response time of less than 1 µs, the device is capable of quickly detecting overcurrent events. 

The device is rated for operation over an extended temperature range of -40°C to +125°C and is packaged in an 8-pin VSSOP.

• 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.
