Function
Set Reset Time-out Input. Connect a capacitor between this input and ground to select the Reset
Time-out period (t
RP
). t
RP
= 2000 x C
1
(C
1
in μF and t
RP
in ms). If no capacitor is connected,
leave this pin floating.
Ground pin.
Always connect to pin V
CC
(Pin 4).
Supply voltage, and reset threshold monitor input.
Open-Drain, Active-Low reset output. Connect to an external pull-up resistor. Reset changes
from high to low whenever the monitored voltage (V
CC
) drops below the reset threshold voltage
(V
RTH
). Once V
CC
exceeds V
RTH
, Reset remains low for the reset timeout period (t
RP
) and then
goes high.
