Overview
SUPPLY VOLTAGE MONITOR ISSUE 3 – JANUARY 1998 DEVICE DESCRIPTION The ZSM561 is a three terminal under vo l ta ge mo ni t or ci rc ui t f or use i n microprocessor systems.
The threshold voltage of the device has been set to 4.
6 volts making it ideal for 5 volt circuits.
Included in the device is a precise voltage reference and a comparator with built in hysteresis to prevent erratic operation.
The ZSM561 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 ...
