E-L9338MD Typical application Circuitry

E-L9338MD

The E-L9338MD is an octal low-side driver designed for automotive applications, especially for driving non-inductive loads such as lights and buzzers, as well as resistive and capacitive loads. This IC is produced by STMicroelectronics, characterized by its ability to interface directly with microcontrollers and provide robust output performance in harsh automotive environments.

Key Features and Specifications:

- Load Type: Capable of driving incandescent lamps, LEDs, and other non-inductive loads.

- Output Channels: Offers eight low-side output channels.

- Supply Voltage: Operates over a wide range of voltages suitable for automotive applications, typically from 5.5 V to 36 V.

- Output Current: Each channel can handle substantial continuous current, ideal for direct control of automotive lamps and actuators.

- Protection Features: Includes overcurrent protection, overtemperature shutdown, and open-load detection, enhancing reliability and safety.

- Package: Available in a PowerSSO24 package, designed to optimize PCB space and thermal dissipation.

Application Scenario: Automotive Exterior Lighting System

In this scenario, the E-L9338MD is used to control various exterior lights of an automobile, such as headlights, taillights, and turn signals, interfacing with the vehicle's body control module.

Circuit Design Methodology:

1. Power Supply Connection:

- Stable Power Source: Connect Vcc (pin 24) to a 12V automotive battery supply. Include a capacitor (e.g., 10 µF) near the power supply pin to stabilize input power and filter out voltage spikes.

2. Microcontroller Interface:

- Control Signal Inputs: Connect each of the eight input pins (IN0 to IN7, pins 2, 3, 4, 5, 6, 7, 8, and 9) to corresponding output pins on a microcontroller. Use pull-down resistors (e.g., 10kΩ) on these lines to ensure defined levels when the microcontroller outputs are inactive.

3. Output to Lights:

- Driving the Loads: Connect each of the eight output pins (OUT0 to OUT7, pins 13, 14, 15, 16, 17, 18, 19, and 20) directly to different lights in the vehicle's exterior lighting system. Ensure that each connection is capable of handling the expected current load, and consider using external fuses for overcurrent protection.

4. Grounding and Layout:

- System Grounding: Connect all ground pins (GND, pins 1, 10, 11, 12, 21, 22, and 23) to the vehicle's chassis ground. This common grounding helps in minimizing electrical noise and potential ground loop issues.

5. Diagnostic Feedback:

- Monitoring Fault Conditions: Utilize the diagnostic feedback (pin 25) to monitor the status of the outputs. Connect this pin to an ADC input of the microcontroller to detect any fault conditions like open-load or thermal shutdown.

Design Considerations:

- Electromagnetic Interference (EMI): Given the automotive environment, design the PCB with careful consideration of EMI. Use shielding and proper routing techniques to minimize interference from high-current switching.

- Thermal Management: Ensure that the PCB layout facilitates effective heat dissipation. Place the E-L9338MD in a location with adequate airflow and consider additional heat sinking if necessary.

- Signal Integrity: Maintain short and direct routing for control signals to prevent delays and distortions, especially important in a system with multiple drivers and loads.

- Reliability and Safety: Implement redundant systems for critical lighting functions like headlights and brake lights to ensure safety in case of a single channel failure.

- System Testing: Conduct extensive testing under various operational conditions to validate the robustness of the lighting system, particularly focusing on the durability and responsiveness of the E-L9338MD in real-world automotive environments.

Utilizing the E-L9338MD in an automotive exterior lighting system demonstrates its effectiveness in managing multiple high-current loads reliably and safely, making it an excellent choice for modern vehicle body control applications. This setup not only ensures operational efficiency but also enhances vehicle safety and compliance with automotive lighting standards.
