Part Number : MAX809L
Function : 3-Pin Microprocessor Reset Circuits / 140ms min Power-On Reset Pulse Width
Manufacturers : Maxim Integrated
The MAX803/MAX809/MAX810 are microprocessor (µP) supervisory circuits used to monitor the power supplies in µP and digital systems. They provide excellent circuit reliability and low cost by eliminating external compo nents and adjustments when used with +5V, +3.3V, +3.0V, or +2.5V powered circuits.
These circuits perform a single function: they assert a reset signal whenever the VCCsupply voltage declines below a preset threshold, keeping it asserted for at least 140ms after VCChas risen above the reset thresh old. Reset thresholds suitable for operation with a vari
ety of supply voltages are available.
