Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The TPS3840-Q1 series voltage monitor or reset IC can operate at high voltage levels while maintaining very low quiescent current over the entire VDD and temperature range. tp_HL = 30µs typical The TPS3840-Q1 offers the best combination of low power consumption, high accuracy and low propagation delay. The reset output signal is set when the voltage on VDD drops below the negative voltage threshold (VIT-) or when manual reset is pulled to low logic (VMR_L). The reset signal is cleared when VDD rises above VIT- plus hysteresis (VIT+) and when the manual reset (MR) is suspended or above VMR_H and the reset delay time (tD) has expired. The reset delay time can be programmed by connecting a capacitor between the CT pin and ground. For fast resets, the CT pin can be left dangling.

• 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.
