The VCC rises up to 4.7 V, then RST2 generates high. The voltage at TC pin is 2 V, then RST2 generates high, when 4 V, C1 is discharged and RST1 generates low. The voltage at TC pin falls to 2 V, then RST1 generates high unless normal clock signal is entered to WD pin, RST1 repeats this operation. Before the voltage at TC pin reaches 4 V, if normal clock signal is entered to WD pin, low RST1 is canceled. In the case of entrance of abnormal signal input, as the waveform of TC pin repeats charge and discharge of RST1 alternatively from 2 V to 4 V, the RST1 repeats high and low output operation. The VCC falls to 4.6 V, then RST2 generates low, this detective voltage has a 100 mV hysteresis. When VCC goes down to 4.25 V(VTH1), the status of TC pin is switched to discharge. When the potentional at TC pin is detected being VTH3(H) or VTH3(L), the status of RST1 becomes "low". 0V 0V Terminology tRST(1): tWD : tRST(2): Time required for TC pin potential to rise from 0 V VTH3(L) when VCC is being applied. Time required for TC pin potential to rise from VTH3(L) to VTH3(H). Time required for TC pin potential to go down from VTH3(H) to VTH3(L). 0V 0V VCC (1): (2): (3), (4): (5): (6), (7): (8), (9): (10): (11): VIN TC RST1 RST2 VTH3(H) VTH2(H) VTH1 VTH2(L) VTH1 VTH3(L) tRST(1) tWD tRST(2) Figure 1 Operating Waveform |
