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.
