Overview
The TDE1707CFP, produced by STMicroelectronics, is a 0.5 A integrated power switch designed with a power supply capability of up to 48 V. This device supports 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 AUX voltage. The TDE1707CFP features internal protections against abnormal conditions such as overcurrent, short-circuit, and overtemperature, ensuring reliable operation. It also includes an adjustable delay at switch-on and an indicator status LED driver for monitoring the output status.
