Figures 1-40 and 1-41 show a typical application circuit and pin configuration, respectively, for the MAXTO4T/S/R. The ICs are similar to that described for Figs.1-J through 1-M, but with generally lower cost, and for use with 3.0-V/3.3-V systems. The ICs have a 200-ms reset time delay, 50-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 supply other than 3.0 V or 3.3 V. The T, S, and R versions have different threshold levels, as shown in Fig. 1-42. MAXIM NEW RE[,EASES DATA Book, 1994, p 5-43.
