... M5295AL/AP/AFP Watchdog Timer Description M5295A is a semiconductor integrated circuit which is designed for system reset to detect +5 V 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 possible to vary the two detective voltage by connecting the resistor suitable to high quality and high performance system ...
