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.
