Overcurrent protection
A hardware overcurrent protection has been implemented through a comparator. The typical
transition speed under the 5 V supply is about 2 µs from 50 mV overdrive.
Figure 13.
Overcurrent protection circuit
With the resistor values actually used in the circuit schematic:
R1= 15 k
Ω, R2=3 kΩ and Rshunt=0.1 Ω
it results:
Equation 11
that fixes the overcurrent threshold peak value at 8.33 A.
