DESCRIPTION

The TDE1897C/TDE1898C is a monolithic Intelli-

gent Power Switch in Multipower BCD Technol-

ogy, for driving inductive or resistive loads. An in-

ternal Clamping Diode enables the fast demag-

netization of inductive loads.

Diagnostic for CPU feedback and extensive use

of electrical protections make this device inher-

ently indistructible and suitable for general pur-

pose industrial applications.
