STM6321SWY6F

STM6321SWY6F
5-pin supervisor with watchdog timer and push-button reset,Trec = 140 ms to 280 ms,Vrst = 2.850 to 3.000 V , SOT25-5, STM, RoHS

---

The STM6321 supervisors are self-contained devices which provide microprocessor supervisory functions. A precision voltage reference and comparator monitors the VCCinput for an out-of-tolerance condition. When an invalid VCCcondition occurs, the reset output (RST) is forced low (or high in the case of RST).

Features:

• Precision V_CCmonitoring of 5, 3.3, 3, or 2.5 V power supplies
• Vrst = 2.850 to 3.000 V;
• RSToutputs (active low, push-pull or open drain)
• RST outputs (active high, push-pull)
• Reset pulse width of 140 ms to 280 ms (typ.)
• Watchdog timeout period of 1.6 s (typ.)
• Manual reset input (MR)
• Low supply current - 3 µA (typ.)
• GuaranteedRST(RST) assertion down to V_CC= 1.0 V
• Operating temperature: –40 to +85 C (industrial grade)
• RoHS compliance Lead-free components are compliant with the RoHS directive
