Remote/Local Temperature Sensor
with SMBus Serial Interface
MAX1617
Maxim Integrated
Slave Addresses
The MAX1617 appears to the SMBus as one device
having a common address for both ADC channels. The
device address can be set to one of nine different val-
ues by pin-strapping ADD0 and ADD1 so that more
than one MAX1617 can reside on the same bus without
address conflicts (Table 9).
The address pin states are checked at POR only, and
the address data stays latched to reduce quiescent
supply current due to the bias current needed for high-Z
state detection.
The MAX1617 also responds to the SMBus Alert
Response slave address (see the Alert Response
Address section).
POR and UVLO
The MAX1617 has a volatile memory. To prevent ambigu-
ous 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).
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 00h to facilitate quick
remote Receive Byte queries.
" T
HIGH
and T
LOW
registers are set to max and min
limits, respectively.
