TLE4251G Description

Short technical summary and product information.

The Infineon TLE4251G is a monolithic integrated low drop voltage tracker designed for demanding automotive applications. It is qualified according to AEC-Q100, ensuring reliability under severe conditions.

This device features an output tracking tolerance of up to ±0.2% for loads up to 300mA, and ±0.5% for loads up to 400mA. It supports a wide operating voltage range up to 40V and operates across a temperature range of -40°C to 150°C. The TLE4251G includes essential protection functions such as short-circuit protection, overtemperature protection, and reverse polarity proofing.

With an enable function, the TLE4251G can be switched to a stand-by mode, significantly reducing current consumption, making it suitable for low-power battery applications. It is available in standard PG-TO252-5 and PG-TO263-5 packages, suitable for surface mount applications.

Potential applications include general automotive systems requiring stable voltage tracking, such as sensor supply under harsh automotive conditions.
