The TLE4274 V50 is an adjustable low-drop linear voltage regulator from Infineon Technologies and primarily used in automotive applications. It\'s specifically designed to provide a voltage regulation of 5V to a large load step of 35A. The IC is available in the SO-8 package and able to withstand extreme power stress condition. It also has several safety and protection features.
Application Field
The primary application field of TLE4274 V50 is automotive products. Specifically, it is widely used in the automotive powertrain and automotive power electronics fields, such as combustion engine control, transmission and auxiliaries, as well as in sensors, actuators, and electronic control units, etc. It is also an ideal power supply for standard and specialized microcontrollers and amplifiers operating in the temperature range from -40° to +125°C.
Working Principle
The TLE4274 V50 works on the principle of a linear voltage regulator. It is based on a voltage regulation circuit, in which the output voltage is compared with a reference voltage and a variable voltage drop is achieved by controlling the current flow. This is achieved by controlling the gate-source voltage of a power MOSFET, which is placed between the input voltage and the output voltage. The IC also has integrated protection functions such as reverse battery protection, battery overvoltage protection and load dump protection. It also provides internal protection against overheating and excessive current.
The device operates in near constant temperature mode. In this mode, the device automatically adjusts the junction temperature to the threshold set by the temperature limit. This has the advantage of providing more reliable performance and better power supply regulation compared with traditional linear regulators. The device can also detect an overcurrent condition and switch off the output voltage if an overload is detected.
Conclusion
The TLE4274 V50 is a linear voltage regulator from Infineon Technologies, specifically designed to provide a voltage regulation of 5V to a large load step of 35A. It\'s primarily used in the automotive powertrain and automotive power electronics fields, such as combustion engine control, transmission, and auxiliaries, as well as in sensors and actuators. The device works on the principle of a linear voltage regulator, in which the output voltage is compared with a reference voltage and a variable voltage drop is achieved by controlling the current flow.
