Exposure to absolute maximum rating conditions for extended periods may affect reliability. Functional operation of the device at any conditions beyond those indicated in the Recommended Operating Conditions section is not implied. ESD SENSITIVITY CAUTION This integrated circuit can be damaged if ESD protections are not considered carefully. SGMICRO recommends that all integrated circuits be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage. ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to damage because even small parametric changes could cause the device not to meet the published specifications. DISCLAIMER SG Micro Corp reserves the right to make any change in circuit design, or specifications without prior notice. NOTE: 1. It is recommended to use the standard timing with a CCWD capacitor from 0.1nF to 1000nF,and offer tWD_TYP from 0.613ms to 3.33s accordingly; If using extended timing, offer tWD_TYP from 0.613ms to 3.33s accordingly.

Connecting the CWD pin to GND via a capacitor to set the watchdog timeout. Connecting the CWD pin to VCC via a 10kΩ resistor or leaving it unconnected to select the preset watchdog timeout. 3 nMR I Manual Reset Input Pin. It is an active-low reset input internally pulled up to VCC. 4 GND G Ground Pin. 5 SET I Logic Input Pin. Connecting the SET pin to GND will disable the watchdog timer. The SET pin selects the watchdog timeouts with CWD pin. 6 WDI I Watchdog Input Pin. The WDI falling edge must appear within the timeout (tWD) period. When nWDO or nRESET is low and the watchdog is disabled, WDI will be ignored. 7 nWDO O Watchdog Output Pin. If the watchdog timeout occurs, the nWDO goes low within an nRESET timeout delay (tRST). Then the nWDO enters in a high-Z state 8 nRESET O Active-Low Reset Output Pin. nRESET remains low if VCC is below the under-voltage threshold. nRESET timeout counter starts if VCC is operating normally. And nRESET goes high if the counter completed. Exposed Pad — G Exposed Pad. It is internally connected to GND. NOTE: I: Input; O: Output; G: Ground.
