TL7700CPSR

The TL7700CPSR is a Voltage Supervisor with active-low open-drain output. The 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 0.5V 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 1.5V temperature-compensated voltage reference from which all function blocks are supplied. Circuit function is very stable, with supply voltage in the 1.8 to 40V range. Minimum supply current allows use with AC line operation and portable battery operation.
