The ZM33164-3 is a three terminal under vol tage monitor circuit for use in 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 ZM33164-3 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 ZM33164-3 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 ZM33164-3 is available in a TO92 package for through hole applications as well as SO8 and SOT223 for surface mount requirements.
