Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The INA302A2QPWRQ1 devices have a high common-mode, bi-directional, current-sense amplifier and two high-speed comparators for detecting out-of-range current conditions.The INA302-Q1 comparator is configured to detect and respond to overcurrent conditions.The INA303 -Q1 comparator is configured to respond to overcurrent and undercurrent conditions in a windowed configuration. These devices have adjustable limit threshold ranges for each comparator setting using external limit setting resistors. These current shunt monitors measure differential voltage signals over a common mode voltage range of -0.1V to +36V independent of the power supply. In addition, these devices will withstand common mode voltages up to 40V.

The open-drain alarm outputs can be configured to operate in either transparent mode (output state is aligned with input state) or latched mode (alarm output clears on latched reset). The alarm response time for Comparator 1 is less than 1µs, while the alarm response time for Comparator 2 is set by an external capacitor and ranges from 2µs to 10s.

The device is powered from a single 2.7V to 5.5V supply and consumes a maximum supply current of 950µA. The device has an extended rated operating temperature range of -40°C to +125°C and is available in a 14-pin TSSOP package.

• 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.
