M62022L,FP
VOLTAGE DETECTING,SYSTEM RESETTING IC
DESCRIPTION
The M62022 is a semiconductor integrated circuit resets logic
circuits according to supply voltage.It is used with many types
of circuits,including central processing units.
With the built-in delay circuit,delay time can be adjusted at
the user’s option by externally adding capacitance.
This circuit can also be used in other applications,such as
battery check,level detection and waveform shaping.
