Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The TPS22917 single-channel load switch uses a low leakage P-channel MOSFET to achieve minimal power losses. The advanced gating design supports operating voltages as low as 1V with minimal increased on-resistance and power losses. The rise and fall times can be independently adjusted using external components for system level optimisation. Inrush current can be managed by adjusting the timing capacitor (CT) and turn-on time without adding unnecessary system delay. The output discharge resistor (QOD) can be used to regulate the output fall time. Connect the QOD pin directly to the output for the fastest fall time, or leave it open for the slowest fall time.

The switch on state is controlled by a digital input which can be directly connected to the low voltage control signal. On first power-up, the device uses a smart pull-down resistor to keep the ON pin unhung until system sequencing is complete. Once the ON pin is deliberately driven high (≥VIH), the smart pull-down resistor (RPD) is disconnected to prevent unnecessary power loss.

• 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.
