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 induc-
tive loads. Diagnostic for CPU feedback and ex-
tensive use of electrical protections make this de-
vice extremely rugged and specially suitable for
industrial automation applications.
