M5295AL/P/FP
WATCHDOG TIMER
DESCRIPTION
M5295A is a semiconductor integrated circuit which is
designed for System Reset to detect +5V power supply.
This IC keeps the operation microcomputer watching.
When the system is abnormal,it generates Reset output until the
system returns to normal states of the System.
It is possible to vary the two detective voltage by connecting the
resistor,so it is suitable to high quality and high performance
system.
FEATURES
•Watch Dog Timer
•Power on Reset Timer
•Low circuit current 0.8mA(Typ,Vcc=5V)
•Wide Range of power supply
