Description
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.
