Trip point is ±1.5% from typical value.
Trip point is ±2.5% from typical value.
Hysterysis is minimum = 1%, maximum = 6% at +25°C.
This specification allows this device to be used in PIC
cuit 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 oper-
ational temperature be maintained between 0°C to +70°C (+25°C preferred). For additional information,
refer to
This parameter is established by characterization and is not 100% tested.
Custom ordered voltage trip point; minimum order volume requirement. Information available upon request.
