LOAD DUMP PROTECTION

Dld is necessary (Voltage Transient Suppressor) if the

load dump peak voltage exceeds VCC max DC rating. The

same applies if the device will be subject to transients on

the VCC line that are greater than the ones shown in the

ISO T/R 7637/1 table.

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.
