Description
The L6370 is a monolithic intelligent power switch
in Multipower-BCD Technology, for driving
inductive or resistive loads. An internal clamping
diode enables the fast demagnetization of
inductive loads. Diagnostic for CPU feedback and
extensive use of electrical protections make this
device extremely rugged and specially suitable for
industrial automation applications.
