Voltage supervisors for use in microprocessor and microcomputer systems

The TL7700 Voltage Supervisors from Texas Instruments are a bipolar integrated circuit designed for using as a reset controller in microprocessor and microcomputer systems. The SENSE voltage can be set to any value higher than 0.5V using two external resistors. Circuit function is extremely stable, with a supply voltage in the 1.8V to 40V range. Minimum supply current enables use with AC line operation, portable battery operation, and automotive applications. The device is designed for operation from –40C to 85C. Typical applications include DSPs, MCUs, FPGAs, ASICs, notebooks, desktop computers, set-top boxes, industrial control systems.
