Product Summary

The TL7700CPSR 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 TL7700CPSR includes a precision voltage reference, fast comparator, timing generator, and output driver, so the TL7700CPSR can generate a power-on reset signal in a digital system.
