µC I/Os PROTECTION:

If a ground protection network is used and negative

transients are present on the VCC line, the control pins will

be pulled negative. ST suggests to insert a resistor (Rprot)

in line to prevent the µC I/Os pins to latch-up.

The value of these resistors is a compromise between the

leakage current of µC and the current required by the

HSD I/Os (Input levels compatibility) with the latch-up limit

of µC I/Os.

-VCCpeak/Ilatchup ≤ Rprot ≤ (VOHµC-VIH-VGND) / IIHmax

Calculation example:

For VCCpeak= - 100V and Ilatchup ≥ 20mA; VOHµC ≥ 4.5V

5kΩ ≤ Rprot ≤ 6kΩ.

Recommended Rprot value is 5kΩ.
