元器件交易网809, CAT810DETAILED DESCRIPTIONSRESET TIMINGThe reset signal is asserted LOW for the CAT809 and HIGH for the CAT810 when the power supply voltage falls belowthe threshold trip voltage and remains asserted for at least 140ms after the power supply voltage has risen above 5VSupplyVoltage0VThresholdVoltageReset Timeout Period140msminimumRESET5V0V5VCAT809RESET0VCAT810FIGURE 1. RESET TIMING DIAGRAMVCC TRANSIENT RESPONSEThe CAT809/810 protect µPs against brownout failure. Short duration transients of 4µsec or less and 100 mVamplitude typically do not cause a false 2 shows the maximum pulse duration of negative-going VCC transients that do not cause a reset condition. Asthe amplitude of the transient goes further below the threshold (increasing VTH - VCC), the maximum pulse durationdecreases. In this test, the VCC starts from an initial voltage of 0.5V above the threshold and drops below it by theamplitude of the overdrive voltage (VTH - VCC).30TRANSIENT
