DESCRIPTION
The L6375 is a monolithic fully protected, full diag-
nostic 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 feedback and extensive use of electrical pro-
tections make this device extremely rugged and spe-
cially suitable for industrial automation applications.
