11 / 23 page tpo tpo RESET Vhys VCC 1.5 V T T Vs’ TL7700 www.ti.com SLVS220F – JULY 1999 – REVISED AUGUST 2011 A. The sense voltage, Vs', is different from the SENSE terminal input voltage, Vs. Vs normally is 500 mV for triggering. Figure 20. VCC-RESET Timing Chart Output Pulse-Duration Setting Constant-current charging starts on the timing capacitor when the sensing-line voltage reaches the TL7700 sense voltage. When the capacitor voltage exceeds the threshold level of the output drive comparator, RESET changes from a low to a high level. The output pulse duration is the time between the point when the sense-pin voltage exceeds the threshold level and the point when the RESET output changes from a low level to a high level. When the TL7700 is used for system power-on reset, the output pulse duration, tpo, must be set longer than the power rise time. The value of tpo is: tpo = Ct × 10 5 seconds Where: Ct is the timing capacitor in farads There is a limit on the device response speed. Even if Ct = 0, tpo is not 0, but approximately 5 μs to 10 μs. Therefore, when the TL7700 is used as a comparator with hysteresis without connecting Ct, switching speeds (tr/tf, tpo/tpd, etc.) must be considered.
