MAX6316–MAX6322
5-Pin P Supervisory Circuits with
Watchdog and Manual Reset
_______________________________________________________________________________________
3
Note 3: This is the minimum time RESET must be held low by an external pulldown source to set the active pullup flip-flop.
Note 4: Measured from RESET VOL to (0.8 x VCC), RLOAD =
∞.
Note 5: WDI is internally serviced within the watchdog period if WDI is left unconnected.
Note 6: The WDI input current is specified as the average input current when the WDI input is driven high or low. The WDI input is
designed for a three-stated-output device with a 10A maximum leakage current and capable of driving a maximum capaci-
tive load of 200pF. The three-state device must be able to source and sink at least 200A when active.
