DEVICE DESCRIPTION

The ZM33164-3 is a three terminal under

v o l t a g e m o n i t or c ir c ui t fo r u s e i n

microprocessor systems. The threshold

voltage of the device has been set to 2.68

volts making it ideal for 3 volt circuits.

Included in the device is a precise voltage

reference and a comparator with built in

hysteresis to prevent erratic operation. The

ZM33164-3 features an open collector output

capable of sinking at least l0mA which only

requires a single external resistor to

interface to following circuits.

Operation of the device is guaranteed from

one volt upwards, from this level to the

device threshold voltage the output is held

low providing a power on reset function.

Should the supply voltage, once established,

at any time drop below the threshold level

then the output again will pull low.

The device is available in a TO92 package for

through hole applications as well as SOT223

for surface mount requirements.
