General Description
The MCP111/112 are voltage-detecting devices
designed to keep a microcontroller in reset until the
system voltage has stabilized at the appropriate level
for reliable system operation. These devices also
operate as protection from brown-out conditions when
the system supply voltage drops below the specified
threshold voltage level. Eight different trip voltages are
available.

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

3: This specification allows this device to be used in PIC
®
microcontroller applications that require the In-Circuit Serial
Programming™ (ICSP™) feature (see device-specific programming specifications for voltage requirements). This
specification DOES NOT allow a continuous high voltage to be present on the open-drain output pin (V
OUT
). The total
time that the V
OUT
pin can be above the maximum device operational voltage (5.5V) is 100 sec. Current into the V
OUT
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 information, please refer to Figure 2-28.
