ZSM561  
ISSUE 3 – JANUARY 1998  
DEVICE DESCRIPTION  
FEATURES  
The ZSM561 is a three terminal under  
voltage monitor circuit for use in  
microprocessor systems. The threshold  
voltage of the device hasbeen set to 4.6 volts  
making it ideal for 5 volt circuits.  
SO8, SOT223 and TO92 packages  
Power on reset generator  
Automatic reset generation  
Low standby current  
Guaranteed operation from 1 volt  
Wide supply voltage range  
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.  
Internal clamp diode to discharge  
delay capacitor  
4.6 volt threshold for 5 volt logic  
20mV hysteresis prevents erratic operation  
APPLICATIONS  
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.  
Shouldthesupplyvoltage, onceestablished,  
at any time drop below the threshold level  
then the output again will pull low. Also  
included is a 6 volt zener diode connected  
between Vcc and Gnd. With just the addition  
of a low cost external NPN transistor and  
resistor, this zener allows the ZSM561 to  
provide both regulator and supply monitor  
functions  
Microprocessor systems  
Computers  
Computer peripherals  
Instrumentation  
Automotive  
Battery powered equipment  
The device is available in a TO92 package for  
through hole applicationsaswell asSO8 and  
SOT223 for surface mount requirements.
