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.

Note 1:
Trip point is 1.5% from typical value.

Hysterysis is minimum = 1%, max = 6% at +25C.
4:
This specification allows this device to be used in PICmicro
microcontroller applications that require the
In-Circuit Serial ProgrammingTM (ICSPTM) feature (see device-specific programming specifications for
voltage requirements). The total time that the RST pin can be above the maximum device operational volt-
age (5.5V) is 100s. Current into the RST pin should be limited to 2 mA. It is recommended that the device
operational temperature be maintained between 0C to +70C (+25C preferred). For additional informa-
tion, refer to Figure 2-35.
5:
This parameter is established by characterization and is not 100% tested.
