DESCRIPTION

The TDE1897R/TDE1898R 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.

This is advanced information on a new product now in development or undergoing evaluation. Details are subject to change without notice.
