ST AN1213 handbook
This document evaluates the TDE1707 power switch, specifically designed for proximity detectors, focusing on its performance in industrial environments. It compares the noise immunity of the original silicon version against the improved TDE1707-B (Rev. B) version using IEC 801/4 burst immunity tests. The analysis details how external capacitors affect immunity levels and identifies the optimal capacitor values for both silicon revisions.

Questions answered in these manuals
What is the recommended capacitor value for the TDE1707 Rev. B to ensure short circuit protection?
A delay capacitor of 68pF on pin 3 is required to prevent protection failure at turn-on when the device is cold.
From: ST AN1213 handbook
How does the TDE1707 Rev. B perform regarding noise immunity compared to the old version?
The Rev. B version has higher immunity; without a delay capacitor, it withstands +2500 / -2500 V, whereas the old version only reaches +300 / -800 V without an output capacitor.
From: ST AN1213 handbook
Where should filter capacitors be placed for the TDE1707?
Filter capacitors are recommended on both the power supply (+Vs pin) and the +5 V regulated voltage (Vreg pin).
