Layout and Bypassing
For better noise immunity, bypass each of the voltage-
detector inputs to GND with a 0.1F capacitor installed
as close to the device as possible. Bypass VCC and
DBP to GND with 1F capacitors installed as close to
the device as possible. VCC (when not externally sup-
plied) and DBP are internally generated voltages and
should not be used to supply power to external circuitry.
Configuration Latency Period
A delay of less than 5s occurs between writing to the
configuration registers and the time when these
changes actually take place, except when changing
one of the voltage-detector thresholds. Changing a
voltage-detector threshold typically takes 150s. When
changing EEPROM contents, a software reboot or
cycling of power is required for these changes to trans-
fer to volatile memory.
