... 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 to the wrong state, a pull-down resistor should be connected to the RESET pin, thus draining such charges to ground and holding RESET low. The resistor value is not critical. A 100kΩ ...

... Monitoring Voltages Other Than V The IMP705-708 can monitor voltages other than V Power Fail circuitry resistive divider is connected from the voltage to be monitored to the Power Fail input, PFI, the PFO (output) will go LOW if the divider voltage goes below its 1.25V reference. Should hysteresis be desired, connect a resistor (equal to approximately 10 times the sum of the two resistors in the divider) between the PFI and PFO pins ...
