The address pin states are checked at POR and SPOR
only, and the address data stays latched to reduce qui-
escent supply current due to the bias current needed
for high-Z state detection. A new device address can be
written using the Write Address Command FDh.
The MAX1619 also responds to the SMBus Alert Response
slave address (see the Alert Response Address section).
POR and UVLO
The MAX1619 has a volatile memory. To prevent ambig-
uous power-supply conditions from corrupting the data in
memory and causing erratic behavior, a POR voltage
detector monitors V
CC
and clears the memory if V
CC
falls
below 1.7V (typical, see Electrical Characteristics table).
When power is first applied and V
CC
rises above 1.75V
(typical), the logic blocks begin operating, although reads
and writes at V
CC
levels below 3V are not recommended.
A second V
CC
comparator, the ADC UVLO comparator,
prevents the ADC from converting until there is sufficient
headroom (V
CC
= 2.8V typical).
The SPOR software POR command can force a power-on
reset of the MAX1619 registers via the serial interface. Use
the SEND BYTE protocol with COMMAND = FCh. This is
most commonly used to reconfigure the slave address of
the MAX1619 on the fly, where external hardware has
forced new states at the ADD0 and ADD1 address pins
prior to the software POR. The new address takes effect
less than 100祍 after the SPOR transmission stop condition.
Power-Up Defaults:
"  Interrupt latch is cleared.
"  Address select pins are sampled.
"  ADC begins auto-converting at a 0.25Hz rate.
"  Command byte is set to 01h to facilitate quick
remote Receive Byte queries.
"  T
HIGH
and T
LOW
registers are set to +127癈 and
-55癈, respectively.
"  T
MAX
and T
HYST
are set to +100癈 and +95癈,
respectively.
"  OVERT polarity is active low.
