The TLE4274GV85ATMA2 is a linear voltage regulator developed by Infineon Technologies. It is classified as part of thePower Management Integrated Circuit (PMIC) – Voltage Regulators – Linear family. This voltage regulator is normally utilized for fault-tolerant solutions in automotive applications.

The TLE4274GV85ATMA2 is designed to provide a robust power supply for applications that require constant and firmly regulated voltage during wide variations in load and input voltage. It can provide a maximum continuous output current of 1.5 A at a peak output of 2.5 A to keep the system running even during peak loading. Under nominal conditions, the output voltage is regulated to 12 V, with an operating range of 6 V to 18 V. With its high temperature range and robust protection mechanism, the device is designed to withstand typical temperature ranges used in automotive applications. Furthermore, the TLE4274GV85ATMA2 comes with a Power-on-Reset (PoR) circuit with an adjustable preset level.

The TLE4274GV85ATMA2 can be used in many different applications. Some of the most common include automotive lighting and control systems, airbag systems, automotive engine control systems, and power supplies for sensors and actuators. It is also suitable for engine control units, audio systems, and battery management systems. Moreover, it can be employed in industrial tools, off-highway and agriculture equipment, and in various other automotive applications.

The working principle behind the TLE4274GV85ATMA2 is fairly simple and is relatively similar to other linear voltage regulators. Current passes from the input side of the device, is regulated, and then driven to the output side. The device operates by setting an output voltage level, which is then regulated and maintained across varying loads and input voltages. As the voltage fluctuates, the output voltage is regulated to remain constant. The TLE4274GV85ATMA2 is designed with a wide operating temperature range and a low-dropout voltage to ensure reliable operation in automotive applications.

The TLE4274GV85ATMA2 also includes a number of features to provide additional levels of protection to the system. It is equipped with Over Voltage Protection (OVP), Under Voltage Lockout (UVLO), and Over Current Protection (OCP) features to limit the output voltage or current levels and protect against overloads or shorts. The OVP feature reduces output voltage levels should they exceed an adjustable over-voltage threshold. The UVLO feature prevents the voltage regulator from turning on when the input voltage is too low or too high, while the OCP feature limits the output current when it exceeds a preset maximum threshold.

Overall, the TLE4274GV85ATMA2 is a linear voltage regulator designed for use in a wide variety of automotive applications. With its wide operating range and robust protection features, it is well suited for applications that require a constant and reliably regulated voltage across varying loads and input voltages. These features make the TLE4274GV85ATMA2 an excellent choice for a variety of automotive applications.
