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 and portable battery operation. The TL7700-SEP device is designed for operation from –55°C to 125°C.
