3 Description

The TL7700 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

device is designed for operation from –40°C to 85°C.
