The V6309 and V6319 are microprocessor supervisory circuits used to monitor the power supplies in µP and digital systems. They provide excellent circuit reliability and low cost by eliminating external components and adjustments when used with 5 V powered or 3 V powered circuits. These circuits perform a single function: they assert a reset signal whenever the VDD supply voltage declines below a preset threshold, keeping it asserted for at least 140 ms after VDD has risen above the reset threshold. The only d...
