    | Partname: | CAT1161WI-42 |  | Description: | Supervisory Circuits with I2C Serial CMOS EEPROM, Precision Reset Controller and Watchdog Timer |  | Manufacturer: |  |  | Datasheet: | PDF (163K). Click here to download *)
 |  | The 1.6-second watchdog circuit returns a system to a known good state if a software or hardware glitch halts or "hangs" the system. The CAT1161 watchdog monitors the SDA line, making an additional PC board trace unnecessary. The lower cost CAT1162 does not have a watchdog timer. |  |  Click here to download CAT1161WI-42 Datasheet*)
