FUNCTION
Input for Manual Pushbutton Reset. Has internal 5μA pullup. Low input activates the
RESET/ RESET outputs.
The voltage-sense input when CTL = V CC . Its threshold is 1.29V. SENSE always

remains connected to the internal comparator. So, when V CC is being monitored
internally (CTL = GND), SENSE should be left open circuit.
Normally NOT used when voltage is monitored through V CC (CTL = GND). When

monitoring through SENSE (CTL = V CC ), HYST allows hysteresis to be added,
reducing noise and spurious reset activity (Figure 3). HYST turns on 5μs before the
RESET/ RESET outputs are activated, and its on-resistance to GND is typically 1k ? .

Ground
Goes low when V CC falls below 4.65V, or when CTL = V CC on the MAX700 goes low
when SENSE falls below 1.29V.
Inverted Version of RESET
When CTL = GND, V CC is monitored by the reset circuit. When CTL = V CC , V CC is ignored
and SENSE is monitored, allowing the threshold to be set with external resistors.
