Description

The TLE4251 is a monolithic integrated low-dropout voltage regulator specifically designed for automotive applications. It provides a stable and regulated 5V output voltage with a high degree of accuracy. The device is capable of supplying output currents up to 400mA and includes comprehensive protection features for robust operation in harsh automotive environments.

Applications

  • Automotive engine management systems: Supplies stable power for microcontrollers and sensors within the engine control unit (ECU).
  • Automotive body control modules: Powers various electronic systems within the vehicle's body, such as lighting, wipers, and door locks.
  • Dashboard instrumentation: Provides regulated power for displays, gauges, and other instrumentation components on the dashboard.
  • Automotive transmission control systems: Regulates voltage for electronic components within the transmission control module (TCM).
  • Industrial control systems: Suitable for use in industrial applications requiring a robust and reliable 5V power supply in harsh environments.

Features

  • Low-dropout voltage: Maintains regulation with input voltages only slightly above the output voltage, improving efficiency.
  • Fixed 5V output voltage: Provides a stable and accurate 5V supply.
  • Output current capability: Supports output currents up to 400mA.
  • Wide input voltage range: Operates with input voltages ranging from 6V to 45V, accommodating a wide range of automotive power supply conditions.
  • Overtemperature protection: Shuts down the regulator to prevent damage in case of excessive temperature.
  • Short-circuit protection: Protects the device and connected components from damage due to output short circuits.
  • Reverse polarity protection: Protects against damage from reverse battery connections.
  • Overvoltage protection: Safeguards the device from excessive input voltage.
  • Reset function: Monitors the output voltage and generates a reset signal if the voltage drops below a predefined threshold.
  • Enable function: Allows the regulator to be turned on and off externally.

Benefits

  • High reliability: Built-in protection features ensure robust operation in automotive environments.
  • Stable output voltage: Provides a consistent 5V supply for sensitive electronic components.
  • Improved efficiency: Low-dropout voltage operation minimizes power dissipation.
  • Simplified system design: Integrated features reduce the need for external components.
  • Enhanced system safety: Protection mechanisms contribute to the overall safety and reliability of the automotive system.

Additional Details

The TLE4251 is typically available in a PG-DSO-8 package. It is qualified according to AEC-Q100 automotive standards. It includes a reset output and enable input, which provides flexibility in system design and control. The reset delay can be configured with an external capacitor. This regulator is suited for applications where a stable and reliable 5V supply is needed under a wide range of input voltage and temperature conditions typical of automotive systems.
