System Reset (with built-in watchdog timer) MM1075
System Reset (with built-in watchdog timer)
Monolithic IC MM1075
Outline
This IC functions in a variety of CPU systems and other logic systems to generate a reset signal and reset the
system accurately during momentary interruption or lowering of power supply voltage.
It also has a built-in watchdog timer for operation diagnosis. This prevents the system from running wild by
generating an intermittent reset pulse during system mis-operation.
Features
1. Built-in watchdog timer
2. Low minimum operating voltage
VCC=0.8V typ.
3. Both positive and negative logic reset output can be extracted
4. Accurate detection of drop in power supply voltage
5. Detection voltage has hysteresis
6. Few external parts
1 capacitor
7. Timer monitoring time can be varied by using an external resistor
Package
DIP-8A (MM1075XD)
SOP-8A (MM1075XF)
Applications
Microcomputer system monitoring, etc.
