Overview
The TDE1707CFPT is a 0.5 A integrated power switch produced by STMicroelectronics. This device is capable of handling power supply voltages up to 48 V and is available in two output configurations: high-side mode (load to GND) and low-side mode (load to VS). It is particularly suited for applications involving proximity detectors and can supply external circuits with its internal +5 V regulated voltage. The TDE1707CFPT includes various protection features such as overload, short-circuit, thermal shutdown, and supply and output reversal protection, making it a robust solution for industrial and automotive applications.
