    VNH7040AYTR Typical application Circuitry


    VNH7040AYTR is a high-side driver IC designed for controlling and driving high-current loads, particularly in automotive applications.


    VNH7040AYTR is commonly used in automotive systems to drive various loads, such as resistive heaters, solenoids, lamps, and motors. It is widely used in automotive applications like seat heaters, power windows, power seats, and engine cooling fans.

    Key Features:

    - VNH7040AYTR integrates four high-side driver channels capable of handling up to 40A continuous current per channel.

    - The chip is built using efficient vertical DMOS technology, allowing for low on-resistance and high current-carrying capability.

    - It offers protection features such as overcurrent protection (OCP), overtemperature protection (OTP), and Undervoltage lockout (UVLO) for safe and reliable operation.

    Example Circuit: Automotive Power Window Control

    Let's consider a specific application where VNH7040AYTR is used to control the power windows of a car:

    1. Load Connection (Power Window Motor):

    - Connect the positive terminal of the power window motor to OUT1 (Channel 1) of VNH7040AYTR.

    - Connect the negative terminal of the power window motor to the automotive ground (GND).

    2. Control Signal Connection (Window Control Switch):

    - Connect the window control switch to the IN1 pin (Channel 1) of VNH7040AYTR. The switch provides the control signal to raise or lower the window.

    3. Power Supply Connection:

    - Connect the VCC pin of VNH7040AYTR to the positive terminal of the car's battery (VBAT).

    - Connect the GND pin of VNH7040AYTR to the automotive ground (GND).

    4. Feedback Signal Connection (Current Sensing):

    - Connect a low-value shunt resistor (Rsense) in series with the power window motor.

    - Connect the FB1 pin (Channel 1 feedback) of VNH7040AYTR to the voltage across the shunt resistor (Rsense) to monitor the motor current.

    Design Considerations:

    When designing the power window control circuit with VNH7040AYTR, consider the following points:

    1. Motor Current Rating: Ensure that the VNH7040AYTR is current rating is sufficient to handle the peak current required by the power window motor during operation.

    2. Protection: Implement overcurrent protection to safeguard the VNH7040AYTR and the power window motor from excessive current.

    3. Motor Stall Current: Consider the stall current of the motor during window jam conditions and design the circuit to handle such high current situations.

    4. Pulse-width modulation (PWM) control: PWM controls the motor speed and direction to produce smooth window motion.

    In conclusion, VNH7040AYTR is a high-side driver chip commonly used in automotive power window control applications. When designing the circuit, considerations should be given to motor current rating, protection, stall current, and PWM control for reliable and safe operation of the power window system in automotive environments.
