Circuit description

L6370

12/19

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

a superimposed ripple. The Under Voltage status is signalled via the DIAG1 and DIAG2

outputs (see the Diagnostic Truth Table 7) .

Demagnetization of inductive loads

An internal zener diode, limiting the voltage across the Power MOS to between 50 and 60V

devices. The maximum energy that can be absorbed from an inductive load is specified as
