Other Fault Signals from μC
Connect a general-purpose output from a μC to one of
the GPI_ inputs to allow interrupts to assert any output
of the MAX6872/MAX6873. Configure one of the pro-
grammable outputs to assert on whichever GPI_ input
connects to the general-purpose output of the μC.
Layout and Bypassing
For better noise immunity, bypass each of the voltage
detector inputs to GND with 0.1μF capacitors installed
as close to the device as possible. Bypass ABP and
DBP to GND with 1μF capacitors installed as close to
the device as possible. ABP 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 5μs 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 volt-
age-detector threshold typically takes 150μs. When
changing EEPROM contents, a software reboot or
cycling of power is required for these changes to trans-
fer to volatile memory.
