... HA16103FPJ/FPK Precautions If the IC’s ground potential varies suddenly by several volts due to wiring impedance (see figure 6), a false RES pulse may be output. The reason for this is that potentials in the RES pulse generating circuit change together with the V GND potential. The reference potential of the comparator in figure 7 and the potential of the external capacitor have different impedances as seen from the comparator, causing a momentary inversion. The solution is to stabilize the ground potential. Two ways of stabilizing the IC’ ...
