L9780TR Typical application Circuitry

The L9780TR is a sophisticated multifunction voltage regulator designed by STMicroelectronics. It's specially created for automotive applications and contains multiple voltage regulators with diverse capabilities.

Key Features of the L9780TR:

1. Versatile Regulation: The L9780TR incorporates a low-drop voltage regulator for 5V and 3.3V output voltage, a high voltage wake-up regulator, and a high precision reference voltage source.

2. Protection Features: The L9780TR chip incorporates features such as Overtemperature Shutdown, Under and Overvoltage Shutdown, and Output Current Limitation for all regulators.

3. Thermal Warning: The device provides a thermal warning function, which is essential for high-performance automotive applications.

Typical Application Scenarios:

Due to its robust feature set and compliance with automotive standards, the L9780TR is particularly well-suited to high-demand automotive applications such as engine control units (ECU), airbag control units, and other onboard electronics.

Example Circuit Connection - Engine Control Unit:

1. Power Supply (Pin VBAT, Pin 28): This pin should be connected to the automotive battery. Care should be taken to ensure that the battery voltage does not exceed the maximum rating of the L9780TR.

2. Ground (GND, Pin 14): This pin should be connected to the ground of the automotive system.

3. Output Pins (OUT5, Pin 20, OUT3V3, Pin 7): The output pins of the voltage regulators can be connected directly to the circuits that require power. These might include microcontrollers, sensors, or other automotive electronics.

4. Enable Pins (EN5, Pin 1, EN3V3, Pin 2): These pins are used to enable or disable the respective voltage regulators. When a high voltage is applied, the regulator is enabled.

Design Considerations with L9780TR:

- Stability of Power Supply: It is essential to ensure the power supply is within the rated voltage and current levels as per the L9780TR datasheet.

- Heat Dissipation: Given its high output and automotive application, heat dissipation should be considered. Using a heat sink or designing a PCB with thermal dissipation in mind might be necessary.

- Protection Mechanisms: Since the L9780TR is used in critical automotive applications, proper protection mechanisms like fuses or transient voltage suppressors should be used to protect against any voltage or current surges.

- Regulator Enable Timing: Care should be taken to manage the timing of the voltage regulator enable pins, especially during system startup or shutdown.

To ensure the correct implementation, please always consult the L9780TR datasheet or other official technical documentation from STMicroelectronics.
