    VNI2140JTR Typical application Circuitry


    The VNI2140JTR is a dual high-side smart solid-state relay from Microelectronics. It provides a compact, low-ON resistance solution for driving a wide range of loads. Here's an elemental guide to connecting the VNI2140JTR:

    1. Power Supply Connections: Join the VCC pin (pin 1) to your power supply. Verify that the voltage being provided is within the range of the data sheet's recommended operating voltage. The power supply ground should be connected to the GND pin (pin 8).

    2. Load Connections: Connect your load between the OUT1 (pin 4) and OUT2 (pin 5) pins and the positive power supply rail. Remember, the VNI2140JTR is a high-side switch, and therefore, it should be placed between the power supply and the load.

    3. Input Pins: The IN1 (pin 3) and IN2 (pin 6) pins control the state of OUT1 and OUT2 respectively. A logic high signal turns the corresponding channel on, and a logic low signal turns it off. Connect these pins to your microcontroller or another logic level signal source.

    4. Diagnostic Outputs: The DIAG1 (pin 2) and DIAG2 (pin 7) pins are diagnostic outputs that provide feedback on the status of the output stages. These pins can be connected to microcontroller inputs or other monitoring circuitry.

    5. Thermal Pad: The central pad beneath the device should be soldered to a large copper plane for better heat dissipation.

    6. Decoupling Capacitor: A decoupling capacitor is recommended between VCC and GND to filter noise from the power supply.

    This guide offers a basic overview. For a more detailed connection process and application-specific information, consult the VNI2140JTR data sheet and relevant application notes. After completing the hardware setup, verify that the load operates as expected when the input pins are driven.
