________________________________________________________________________ http://www.union-ic.com rev.04 dec.2013 7/15 um809/810 detailed description a microprocessor?s (p?s) reset input starts the p in a known state. the um809/810 assert reset to prevent code-execution errors during power- up, power-down, or brownout conditions. they assert a reset signal whenever the v cc supply voltage declines below a preset threshold, keeping it asserted for at least 140ms after v cc has risen above the reset threshold. the um809/810 have a push-pull output stage. applications information v cc transient rejection in addition to issuing a reset to the p dur ing power-up, power-down, and brownout conditions, the um809/810 are relatively immune to short-duration negative-going v cc transients (glitches). figure 7 shows typical transient duration vs. reset comparator overdrive, for which the um809/810 do not generate a reset pulse. the gr aph was generated using a negative-going pulse applied to v cc , starting 0.5v above the actual reset threshold and ending below it by the magnitude indicated (reset comparator overdrive). the graph indicates the maximum pulse width a negative-going v cc transient can have without causing a reset pulse. as the magnitude of the transient increases (goes farther below the reset threshold), the maximum allowable pulse width decreases. typically, for the um8_l and um8_m, a v cc transient that goes 100mv below the reset threshold and lasts 20s or less will not cause a reset pulse. a 0.1f bypass capacitor mounted as close as possible to the v cc pin provides additional transient immunity. figure 7. maximum transient duration vs overdrive for glitch rejection at 25 output signal integrity during power down when v cc falls below 1v, the um809 reset _____________ output no longer sinks current?it becomes an open circuit. therefore, high-impedance cmos logic inputs connected to reset _____________ can drift to undetermined voltages. this presents no problem in most applications since most p and other circuitry is inoperative with v cc below 1v. however, in applications where reset _____________ must be valid down to 0v, adding a pull-down resistor to reset _____________ causes any stray leakage currents to
