19-2336; Rev 0; 1/02 Low-Power, Single/Dual-Voltage µP Reset Circuits with Capacitor-Adjustable Reset Timeout Delay General Description Features The MAX6412–MAX6420 low-power microprocessor ¦ Monitor System Voltages from 1.6V to 5V supervisor circuits monitor system voltages from 1.6V to ¦ Capacitor-Adjustable Reset Timeout Period 5V. These devices are designed to assert a reset signal whenever the VCC supply voltage or RESET IN falls below ¦ Manual Reset Input (MAX6412/MAX6413/MAX6414) its reset threshold or the manual reset input is asserted. ¦ Adjustable Reset Input Option The reset output remains asserted for the reset timeout period after VCC and RESET IN rise above the reset (MAX6415–MAX6420) threshold and the manual reset input is deasserted. The ¦ Dual-Voltage Monit
