System Reset (with built-in watchdog timer) MM1095

System Reset (with built-in watchdog timer)

Monolithic IC MM1095

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

100µA typ.

3. Low operating limit voltage

Vcc=0.8V

4. Watchdog stop function (RCT pin)

5. Few external parts

Package

DIP-8B (MM1095AD, MM1095BD)

SOP-8C (MM1095AF, MM1095BF)

SIP-8A (MM1095AS, MM1095BS)

Applications

1. Reset circuits in microcomputers, CPUs and MPUs

2. Logic circuit reset circuits

3. Microcomputer system monitoring, etc.
