    L9825TR Typical application Circuitry


    The L9825TR is an octal low-side driver IC designed for driving a wide range of loads, such as relays, solenoids, lamps, and other low-side switched devices in automotive and industrial applications.

    Functionality: This chip is capable of controlling up to eight low-side loads with individual output channels, providing built-in protection features such as overcurrent protection, thermal shutdown, and open-load detection.

    Applications: The L9825TR is commonly used in automotive systems for controlling various actuators, in industrial control systems for driving solenoids and relays, and in any application requiring multiple low-side load driving capabilities.

    Parameters: Key specifications include an operating voltage range typically from 5.5V to 36V, output current capability up to 0.6A per channel, and low on-resistance for efficient switching.

    Circuit Design for an Automotive Actuator Control System:

    1. Power Supply Connection: Connect the VCC pin (Pin 1) of the L9825TR to a stable power source within the operating voltage range to power the IC.

    2. Load Connections: Connect each of the eight output pins (OUT1 to OUT8) to the respective loads (such as actuators or relays) that need to be controlled.

    3. Input Signal Connections: Attach the input pins (IN1 to IN8) to the control signals from a microcontroller or other control circuitry to command the switching of the outputs.

    4. Grounding: Ensure proper grounding by connecting the GND pin (Pin 9) to the system ground.

    5. Diagnostic Feedback: Optionally, connect the open-load detection pin (OL) to a microcontroller input to monitor the status of the loads for open-circuit conditions.

    Design Considerations:

    - Input Signal Levels: Ensure that the control signals applied to the input pins are compatible with the logic level requirements of the L9825TR.

    - Load Current: Ensure that each load's current draw is within the L9825TR's maximum output current rating.

    - Thermal Management: To avoid thermal shutdown, give the L9825TR enough heat dissipation, particularly when operating high-current loads.

    - Protection Diodes: Consider adding external protection diodes to the outputs if inductive loads are being driven to protect against voltage spikes.

    By following these guidelines, the L9825TR can be effectively integrated into an automotive actuator control system, providing reliable and efficient control of multiple low-side loads.
