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.
FEATURES
•Requires only a few external components.
•Ensures long delay time at low capacitance.
e.g.Delay time is 100ms at 0.33µF.
•Limit operating voltage*is low.
0.6V standard(Resistance RL=22kΩ)
(*Minimum supply voltage at which output can be kept low.)
•Wide supply voltage range.....................2~17V
•Highly resistant to rapid voltage fluctuation
•Wide application range
•5-pin single in-line package equivalent in height to dual in-line
package
