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. The hysteresis value of the sense voltage also can be set by the same resistors. The device includes
a precision voltage reference, fast comparator, timing generator, and output driver, so it can generate a
power-on reset signal in a digital system.
The TL7700 has an internal 1.5-V temperature-compensated voltage reference from which all function blocks
are supplied. 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 TL7700C is characterized for operation from –40°C to 85°C.
