www.austriamicrosystems.com revision 0.93 8 - 15 as1910 - as1915 austria micro systems data sheet reset/resetn 8 detailed description the as1910 - as1915 supervisory circuits were designed to generate a reset when one of the two monitored supply voltages falls below its factory-trimmed trip threshold (see v th on page 3 and v th2 on page 3 ), and to maintain the reset for a minimum timeout period (see t rp on page 4 ) after all supplies have stabilized. the integrated watchdog timer (see watchdog input on page 10) helps mitigate against bad programming code or clock signals, and/or poor peripheral response. an active-low manual reset input (see manual reset input on page 10) allows for an externally activated system reset. reset/resetn whenever one of the monitored voltages falls below its re set threshold, the reset out put (as1910, as1912, as1913, as1915) asserts low or the resetn outp ut (as1911, as1914) asse rts high. once all monito red voltages have stabi- lized, an internal timer keeps the reset asserted for the reset timeout period (t rp ). after the t rp period, the reset or resetn output return to their original state (see figure 10) . figure 9. functional diagram of v cc supervisory application figure 10. reset timing diagram as1913/as1914/as1915 reset timeout delay generator watchdog transition detector watchdog timer + ? 1.26v v cc 0.63v 1.26v 5 v cc2 2 gnd 6 v cc 4 wdi 1 resetn/ reset 3 mrn 1v t rd t rp t rp t rd v th v th v cc resetn reset gnd 1v
