The "TLE4285G" is a part of the Infineon Technologies product family, specifically a voltage regulator designed for automotive applications. It is commonly used for power supply management in automotive systems, including microcontrollers, sensors, and other electronic systems that require regulated voltage.
Package Type
The TLE4285G is typically available in TO-263 package type. This is a surface-mount package with three pins or leads that connect the component to the PCB.
Pin Function Specifications:
The pinout for the TLE4285G is as follows (based on the TO-263 package type):
Pin Number Pin Name Pin Function Description 1 IN Input Pin: Connects to the input voltage source. Usually connected to a DC voltage source of 5 to 40V. 2 GND Ground Pin: Connects to the system ground. This is the reference point for all voltages in the circuit. 3 OUT Output Pin: Provides a regulated voltage (typically 5V or 3.3V) to the system from the input voltage. 4 ON/OFF Enable Pin: Used to turn the regulator on or off. A high logic level enables the device, while a low logic level disables it. 5 Vref Reference Voltage: Provides the internal reference voltage for the regulator's control circuit. 6 NC (No Connect) No Connect: This pin does not have any electrical connection in the package. 7 Adjust (Adj) Adjustment Pin: Used to set the output voltage using external resistors (for adjustable voltage versions).Explanation of the Full Pinout (Including All Functions):
In the TO-263 package, the TLE4285G has a total of 7 pins. The essential pins include the input voltage, ground, and output voltage pins. The ON/OFF pin allows users to control the activation of the regulator, and the Vref pin is used for internal regulation.
If the Adjust pin is used, external resistors set the output voltage. In some configurations, the NC (No Connect) pin doesn't serve a functional role and just provides mechanical stability in the package.
