Description
The MCP131X/2X are voltage supervisor devices
designed to keep a microcontroller in Reset until the
system voltage has reached and stabilized at the
proper level for reliable system operation. The table
below shows the available features for these devices.
† Notice: Stresses above those listed under “Maximum Ratings” may cause permanent damage to the device. This is a
stress rating only and functional operation of the device at
those or any other conditions above those indicated in the
operational listings of this specification is not implied. Exposure to maximum rating conditions for extended periods may
affect device reliability.
