Input for Manual Pushbutton Reset. Has internal 5µA pullup. Low input activates the
RESET/RESET outputs.
The voltage-sense input when CTL = V
remains connected to the internal comparator. So, when V
internally (CTL = GND), SENSE should be left open circuit.
Normally NOT used when voltage is monitored through V
monitoring through SENSE (CTL = V
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 1kΩ.
