... IMP705/706/813L feature a 1.6 second watchdog timer. The IMP707/708 have both active-HIGH and active-LOW reset outputs but no watchdog function. The IMP813L has the same pin-out and functions as the IMP705 but has an active-HIGH reset output. A versatile power-fail circuit has a 1.25V threshold, useful in checking battery levels and non-5V supplies. All devices have a manual reset (MR) input ...

... WDO remains low. CC Unlike RESET, WDO does not have a minimum pulse width and as soon as V exceeds the reset CC threshold, WDO goes HIGH with no delay. Active-HIGH reset output. RESET is the inverse of RESET. The IMP813L has only a RESET output ...

... An external debounce circuit is unnecessary since the 140ms minimum reset time will debounce mechanical pushbutton switches. By connecting the watchdog output (WDO) and MR, a watchdog timeout forces RESET to be generated. The IMP813L should be above 1.2V. During a CC used when an active-HIGH RESET is required. ...

Application Information Ensuring That RESET is Valid Down to V When V falls below 1.1V, the IMP705-708 RESET output no CC longer pulls down; it becomes indeterminate. To avoid the possi- bility that stray charges build up and force RESET ...
