The TL7757 is a supply-voltage supervisor designed for use in microputer and microprocessor systems. The supervisor monitors the supply voltage for undervoltage conditions. During power up, when the supply voltage, VCC, attains a value approaching 1 V, the RESET output bees active (low) to prevent undefined operation. If the supply voltage drops below threshold voltage...
