MCU I/O protection
ST suggests to insert a resistor (Rprot) in line to prevent the microcontroller I/O pins from
latching up(a). The value of these resistors is a compromise between the leakage current of
microcontroller and the current required by the LSD I/Os (input levels compatibility) with the
latch-up limit of microcontroller I/Os:
Equation 1
Let:
Ilatchup > 20 mA
VOHC > 4.5 V
35
Ω ≤ R
prot ≤ 100 KΩ
Then, the recommended value is Rprot = 10 KΩ
Figure 18 shows the turn-off current drawn during the demagnetization.
