SS8037/8(G) Microprocessor Reset IC FEATURES DESCRIPTION Precision monitoring of +3V, +3.3V, and +5V The SS8037/8 are microprocessor (µP) supervisory power-supply voltages circuits used to monitor the power supplies in µP and Fully specified over temperature digital systems. They provide excellent circuit reliability Available in three output configurations and low cost by eliminating external components and adjustments when used with +5V, +3.3V, +3.0V- pow- Push-pull RESEToutput (SS8037L) ered circuits. Push-pull RESET output (SS8037H) Open-drain RESEToutput (SS8038L) These circuits perform a single function: they assert a Power-on reset pulse width of 140ms min reset signal whenever the VCC supply voltage declines Supply current of 10µA below a preset th
