PIN FUNCTIONS

to Table 1). When the monitored input is conﬁgured as a

positive voltage, a reset condition is triggered when the

pin is below 0.5V. When the monitored input is conﬁg-

ured as a negative voltage, a reset condition is triggered

when the pin is above 0.5V. Tie pin to VCC if unused and

conﬁgured as a positive supply. Tie pin to GND if unused

and conﬁgured as a negative supply.

VCC (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.
