Functional description.
At fig. 1 is standard connection circuit of IL9010N IC in collector electric motor control circuit
and motor protection from load current exceeding. In addition, circuit provides protection from
motor overheat (resistor R3).
Motor protection from load current exceeding is implementing through protection circuit,
performed on elements R1, R2, R4 - R7, R17, VD1 – VD3, outputs 13 (direct input of voltage
comparator), 14 (inverting input of voltage comparator), 01 (voltage comparator output) of
