DESCRIPTION
The L6375 is a monolithic fully protected, full diagnostic 0.5A Intelligent Power Switch. it is designed to
drive any kind of R-L-C load with controlled output
voltage slew rate and non dissipative short circuit
protection. An internal Clamping Diode enables the
fast demagnetization of inductive loads. Diagnostic
for CPU feedbackand extensive use of electrical protections make this device extremely rugged and specially suitable for industrial automation applications.
