Parameters Sym Min Typ Max Units Conditions
Note 1: Trip point is ±1.5% from typical value.
2: Trip point is ±2.5% from typical value.
3: Hysteresis is minimum = 1%, maximum = 6% at +25°C.
4: 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). The total time that the RST
pin can be above the maximum device operational
voltage (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
information, refer to Figure 2-35.
5: This parameter is established by characterization and is not 100% tested.
6: Custom ordered voltage trip point; minimum order volume requirement. Information available upon request.
