Figures 1-12 and 1-13 show the block diagram and pin configuration; respectively, for the MAX1259. The IC is similar to that described for Fig. 1-N, and switches to the backup battery when the primary power supply is interrupted. The input-output differential is 200 mV when supplying 250mA from the primary power or 15mA from the battery. The battery-failure output at pin 3 indicates when the battery is below +2 V. The power-fail output at pin 11 indicates when the primary power is low. MAXIM NEW RELEASES DATA BOOK, 1992, P. 5-17.
