... An active-low manual-reset input. The MAX707/MAX708 are the same as the MAX705/ MAX706, except an active-high reset is substituted for the watchdog timer. The MAX813L is the same as the MAX705, except RESET is provided instead of RESET. Two supply-voltage monitor levels are available: The MAX705/MAX707/MAX813L generate a reset pulse when the supply voltage drops below 4 ...

... RESET, WDO does not have a minimum pulse width. As soon as V old, WDO goes high with no delay. Active-High Reset Output is the inverse of RESET. Whenever RESET is high, RESET is low, and vice 7 1 RESET versa (Figure 2). The MAX813L has a RESET output only. FUNCTION is below the CC rises CC is ...

... The MAX705/MAX706 have a watchdog timer and a falls CC RESET output. The MAX707/MAX708 have both active- high and active-low reset outputs. The MAX813L has both an active-high reset output and a watchdog timer. The manual-reset input (MR) allows reset to be trig- gered by a pushbutton switch. The switch is effectively debounced by the 140ms minimum reset pulse width ...

... MR tors and transistor as shown, a high PFO triggers reset. As long as PFO remains high, the MAX705- MAX708/MAX813L will keep reset asserted (RESET = low, RESET = high). Note that this circuit’s accuracy depends on the PFI threshold tolerance, the V and the resistors. Ensuring a Valid RESET ...
