Low_cost_supervisory_circuit_with_battery_backup

Figures 1-30 and 1-31 show a typical application circuit and pin configurations, respectively, for the MAX703/MAX704. The ICs are similar to that described for Figs. 1-J through 1-M, but with generally lower cost. The ICs have a 200-ms reset pulse width, 200-μA quiescent current, 50-nA quiescent with battery backup, and a 1.25-V threshold detector for power-fail warning, low-battery detection, or for monitoring a power supply voltage other than +5 V.
