Figures 1-14 and 1-15 show a typical application circuit and block diagram, respectively, for the MAX690. The IC is similar to that described for Fig. 1-M, but also includes watchdog and battery-backup protection, and has a 1.3-V threshold detector, as shown in Fig. 1-16. Use the equations shown in Fig. 1-M to calculate the values for the resistors at the PFI input (except use a threshold of 1.3 V, instead of 2.54 V). MAXIM NEW RELEASES DATA Book, 1992, P. 5-19, 5-22.
