PIN FUNCTIONS
to Table 1). When the monitored input is confi gured as a
positive voltage, a reset condition is triggered when the
pin is below 0.5V. When the monitored input is confi g-
ured as a negative voltage, a reset condition is triggered
when the pin is above 0.5V. Tie pin to V
CC
if unused and
confi gured as a positive supply. Tie pin to GND if unused
and confi gured as a negative supply.
V
CC
(Pin 16): Supply Voltage. Bypass this pin to GND with
a 0.1μF (or greater) capacitor. Operates as a direct supply
input for voltages up to 6V. Operates as a shunt regulator for
supply voltages greater than 6V and must have a resistance
between the pin and the supply to limit input current to no
greater than 10mA. When used without a current-limiting
resistance, pin voltage must not exceed 6V.
