Description  
Reference  
Voltage  
The MCP1316/16M/17/18/18M/19/19M/20/21/22 are  
voltage supervisor devices designed to keep a micro-  
controller in Reset until the system voltage has reached  
and stabilized at the proper level for reliable system  
operation. This sevice family also offers a Watchdog  
Timer to monitor system operation and a Manual Reset  
input. The table below shows the available features for  
these devices.
