Applications Information
Configuration Download at Power-up
The configuration of the MAX6870/MAX6871 (undervolt-
age/overvoltage thresholds, PO_ timeout periods,
watchdog behavior, programmable output conditions
and configurations, etc.) depends on the contents of
the EEPROM. The EEPROM is comprised of buffered
latches that store the configuration. The local volatile
memory latches lose their contents at power-down.
Therefore, at power-up, the device configuration must
be restored by downloading the contents of the EEP-
ROM (non-volatile memory) to the local latches. This
download occurs in a number of steps:
1) Programmable outputs go high impedance with no
power applied to the device.
2) When ABP exceeds +1V, all programmable out-
puts are weakly pulled to GND through a 10A
current sink.
3) When ABP exceeds UVLO, the configuration EEP-
ROM starts to download its contents to the volatile
configuration registers. The programmable outputs
assume their programmed conditional output state
when download is complete.
4) Any attempt to communicate with the device prior to
this download completion results in a NACK being
issued from the MAX6870/MAX6871.
