SO-14
Description
This device is a monolithic intelligent power switch
in multipower BCD technology for driving
inductive, capacitive or resistive loads.
Diagnostic for CPU feedback and extensive use of
electrical protections make this device inherently
indistructible and suitable for general purpose
industrial applications.
