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.

Trip point is ±1.5% from typical value.
Trip point is ±2.5% from typical value.
Hysterysis is minimum = 1%, max = 6% at +25°C.
This specification allows this device to be used in PICmicro® microcontroller applications that require the
In-Circuit Serial Programming™ (ICSP™) 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 0°C to +70°C (+25°C preferred). For additional informa-
tion, refer to Figure 2-35.
This parameter is established by characterization and is not 100% tested.
Custom ordered voltage trip point; minimum order volume requirement. Information available upon request.

2.0 TYPICAL PERFORMANCE CURVES
Note:
The graphs and tables provided following this note are a statistical summary based on a limited number of
samples and are provided for informational purposes only. The performance characteristics listed herein
are not tested or guaranteed. In some graphs or tables, the data presented may be outside the specified
operating range (e.g., outside specified power supply range) and therefore outside the warranted range.
Note: Unless otherwise indicated, all limits are specified for VDD = 1V to 5.5V, RPU = 100 kΩ (only MCP1316;
see Figure 4-1), TA = -40°C to +125°C.
