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.
