Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The DRV110APWR device is a PWM current controller for solenoid valves. The device is designed to reduce power loss by regulating the current with a well controlled waveform. The fast ramp-up of the solenoid current ensures proper opening of the valve or relay. After the initial rise, the solenoid current will remain peaked to ensure proper operation; thereafter, the current drops to a lower holding level to avoid overheating problems and reduce power loss.

Use an external capacitor to set the peak current duration. The peak and hold levels of the current ramp and the PWM frequency can be set individually using external resistors. The external setting resistors are not even necessary if the default values of the corresponding parameters are suitable for the application.

The DRV110APWR device has an internal Zener diode that limits the input voltage to VZENER for applications that require a higher supply voltage. The internal Zener diode allows the DRV110APWR to be powered from 120V and 230V AC supplies through a rectifier and current limiting resistor. Higher DC voltages, e.g. 48V, can also be regulated in this way.

Features of the DRV110APWR

Internal Zener diode on power supply pin for high voltage operation

Supply from 120V and 230V AC with rectifier and RS resistor

Powered from 24V, 48V and higher AC supplies with RS resistors

Drives an external MOSFET with PWM to control solenoid current

External sense resistor to regulate solenoid current

Fast ramp of solenoid current to ensure activation

Reduces solenoid current in hold mode to reduce power consumption and heat dissipation

Ramp peak current, peak current duration, hold current, and PWM clock frequency can be set externally. These parameters can also be set to nominal values without the use of external components.

• 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?
