3 Description

The TL7700-SEP is a bipolar integrated circuit

designed

for

use

as

a

reset

controller

in

microcomputer and microprocessor systems. The

SENSE voltage can be set to any value greater than

0.5 V using two external resistors.

Circuit function is very stable, with supply voltage in

the 1.8-V to 40-V range. Minimum supply current

allows use with ac line operation, portable battery

operation, and automotive applications. The TL7700-

SEP device is designed for operation from –55°C to

125°C.
