Overview
The TDE1707BFP and TDE1707CFP are 0.5 A integrated power switches developed by STMicroelectronics. These devices are capable of handling power supply voltages up to 48 V and offer two output configurations: high-side (load to GND) and low-side (load to VS) modes. They are particularly suited for applications involving proximity detectors and can supply external circuits with an internal +5 V regulated voltage. The devices include various protection features such as overload, short-circuit, thermal shutdown, and supply/output reversal protection, ensuring reliable operation under various conditions.
