stm6825 5引脚与看门狗定时器和按钮复位

the stm6xxx supervisors are self-contained devices which provide microprocessor supervisory functions. a precision voltage reference and comparator monitors the vcc input for an out-of-tolerance condition. when an invalid vcc condition occurs, the reset output (rst) is forced low (or high in the case of rst). these devices also offer a watchdog timer (except for stm6322/6825) and/or a push-button (mr) reset input.

stm6825 产品特性:

• precision vcc monitoring of 5, 3.3, 3, or 2.5 v power supplies
• rst outputs (active-low, push-pull or open drain)
• rst outputs (active-high, push-pull)
• reset pulse width of 1.4 ms, 200 ms and 240 ms (typ)(a)
• watchdog timeout period of 1.6 s (typ)(a)
• manual reset input (mr)
• low supply current - 3 μa (typ)
• guaranteed rst (rst) assertion down to vcc = 1.0 v
• operating temperature: –40 to +85°c (industrial grade)
• rohs compliance lead-free components are compliant with the rohs directive
