L6370Q

Circuit description

17

Protection shuts off the output whenever the supply voltage falls below the mask fixed by

The hysteresis (see Figure 4) assures a non-intermittent behavior at low supply voltage with

a superimposed ripple. The undervoltage status is indicated by the DIAG1 and DIAG2

outputs (see Table 7).

Demagnetization of inductive loads

An internal Zener diode, limiting the voltage across the power MOSFET between 50 and 60

devices. The maximum energy that can be absorbed by an inductive load is specified as 1J
