Description
The L6375S is a monolithic Intelligent Power
Switch in Multipower BCD Technology, for driving
inductive or resistive loads with controlled output
voltage slew rate and short circuit protection.
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.
