Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The TPS2420RSAR device provides highly integrated load protection for applications up to 20-V. The maximum UV turn-on threshold of 2.9 V makes the TPS2420RSAR well suited to standard bus voltages as low as 3.3 V. The TPS2420RSAR device protects loads, minimizes inrush current, and safely shuts down in the event of a fault. The programmable fault current threshold starts the fault timer while allowing the current to pass to the load uninhibited. The programmable current limit threshold sets the maximum current allowed into the load, for both inrush and severe load faults. Both events use the programmable timer which inhibits all current to the load when it expires.

The dual protection thresholds are useful in applications such as disk drives. The start-up and seek currents are typically higher than the nominal current and during this time the load needs a low impedance path to deliver the power. If a failure at the load occurs, the current limit does not allow the current to exceed the programmed threshold. This protects both the load and the integrity of the power supply. The internal MOSFET is protected by power limit circuitry which ensures that the MOSFET remains within its safe operating area (SOA) during all operating states.

The TPS2420RSAR device also allows the system to monitor load currents with no need for a shunt in the power path. The gain of the current monitor can be scaled to the application. Fault and power good outputs are provided for improved system management and sequencing control.

This device can be programmed to either latch-off or retry in the event of a fault. All of this functionality is packed into a 16-pin 4 × 4 mm QFN 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.
