TPS3840DL40DBVRQ1 - Automotive Nano IQ Voltage Supervisor With MR and Programmable Delay

Product Description

TPS3840DL40DBVRQ1 can operate at high voltage levels while maintaining very low quiescent current across the whole VDD and temperature range. TPS3840-Q1 offers best combination of low power consumption, high accuracy and low propagation delay (tp_HL= 30 µs typical).

Product Features

Wide operating voltage : 1.5 V to 10 V

– Use external resistors to extend Vin range

Nano supply current : 350 nA (Typ), 700 nA (Max)

Fixed threshold voltage (VIT-)

– Threshold from 1.6 V to 4.9 V in 0.1-V steps

– High accuracy: 1% (Typ), 1.5% (Max)

– Built-in hysteresis (VIT+)

– 1.6 V < VIT- ≤ 3.0 V = 100 mV (typical)

– 3.1 V ≤ VIT- < 4.9 V = 200 mV (typical)

Fast start-up delay (tSTRT): 350 µs (Max)

Programmable capacitor-based reset time delay:

– tD: 50 µs (no capacitor) to 6.2 s (10-µF)

Applications

Automotive head unit and cluster

Automotive display, integrated cockpit and driver monitoring

Telematics control unit and emergency call

• 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.
