General Description
The MAX6633/MAX6634/MAX6635 combine a tempera-
ture sensor, a programmable overtemperature alarm,
and an SMBus/I2C-compatible serial interface into
a single package. They convert their die temperatures
into digital values using internal analog-to-digital con-
verters (ADCs). The result of the conversion is then held
in a temperature register as a 12-bit + sign value, allow-
ing 0.0625°C resolution, readable at any time through
the serial interface. The devices are capable of reading
temperatures up to +150°C.
The MAX6633/MAX6634/MAX6635 feature a shutdown
mode that saves power by turning off everything except
the power-on reset (POR) and the serial interface. The
devices can be configured to separate addresses,
allowing multiple devices to be used on the same bus.
The MAX6633 has four address pins, allowing up to 16
devices to be connected to a single bus. The MAX6634
has three address pins, allowing up to eight devices to
be connected to a single bus. The MAX6635 has two
address pins, allowing up to four devices to be con-
nected to a single bus.
The MAX6633/MAX6634/MAX6635 make temperature
data available for transfer over the serial interface. The
MAX6634 incorporates a dual-mode ALERT output
(open drain) and can serve as an upgraded alternative
to the LM75. The MAX6635 includes an ALERT output
and an OVERT output (both open drain) and can func-
tion as an upgraded replacement for the LM76 in most
applications. The MAX6634/MAX6635 feature user-pro-
grammable temperature thresholds. All three devices
come in an 8-pin SO package.
