... TC1275/TC1276/TC1277 3.0 APPLICATIONS INFORMATION 3.1 Operation – Power Monitor The TC1275/TC1276/TC1277 provide the function of detecting out-of-tolerance power supply conditions and warning a processor-based system of impending power failure. When V is detected as out-of- CC tolerance, the RESET signal is asserted. On power-up, RESET is kept active for approximately 200 ms after the power supply has reached the selected tolerance ...

... V Transient Rejection CC The TC1275/TC1276/TC1277 provides accurate V monitoring and reset timing during power-up, power- down, and brownout/sag conditions, and rejects negative-going transients (glitches) on the power supply line. Figure 3-5 shows the maximum transient duration vs. maximum negative excursion (overdrive) for glitch rejection. Any combination of duration and overdrive that lays under the curve will not generate a reset signal ...
