TOL
Threshold Tolerance Input. Connect TOL to GND to select 5% threshold tolerance.
Connect TOL to V CC to select 10% threshold tolerance.
Watchdog Timer Input.
MAX16004: If WDI remains low or high for longer than the watchdog timeout period,
RESET is asserted and the timer is cleared. The timer also clears whenever a reset is
asserted or a rising or falling edge on WDI is detected. The watchdog timer enters a
startup period that allows 54s for the first transition to occur before a reset. Leave WDI
unconnected to disable the watchdog timer.

WDI
MAX16005: If WDI remains low or high for longer than the watchdog timeout period,
WDO is asserted. The timer clears whenever a rising or falling edge on WDI is detected.
Leave WDI unconnected to disable the watchdog timer. The MAX16005 does not have a
startup period.
MAX16004/MAX16005: The WDI open-state detector uses a small 100nA current.
Therefore, do not connect WDI to anything that will source or sink more than 50nA. Note
that the leakage current specification for most three-state drivers exceeds 50nA.

Reset Timeout (s) = 2.06 x 10 6 ( ? ) x C SRT (F). For the internal timeout period of 140ms
(min), connect SRT to V CC .

timeout period after all monitored voltages exceed their respective thresholds and MR is
deasserted. This open-drain output has a 30μA internal pullup.

the IN_ inputs rise above their thresholds. When all the IN_ inputs rise above their
thresholds, WDO asserts low whenever the watchdog timer times out. WDO deasserts
after a valid WDI transition or if MR is pulled low. The watchdog timer begins counting
after the reset timeout period once MR goes high. Pull MARGIN low to deassert WDO .
