DESCRIPTION

The TDE1890/1891 is a monolithic Intelligent

Power Switch in Multipower BCD Technology, for

driving inductive or resistive loads. An internal

Clamping Diode enables the fast demagnetization

of inductive loads.

Diagnostic for CPU feedback and extensive use

of electrical protections make this device ex-

tremely rugged and specially suitable for indus-

trial automation applications.
