8 of 15
provides user access to the temperature register. Bits 3 through 0 of the temperature register are
hardwired to 0. When the device is configured for 12-bit resolution, the 12 MSbs (bits 15 through 4) of
the temperature register contain temperature data. For 11-bit resolution, the 11 MSbs (bits 15 through 5)
of the temperature register contain data, and bit 4 is 0. Likewise, for 10-bit resolution, the 10 MSbs (bits
15 through 6) contain data, and for 9-bit the 9 MSbs (bits 15 through 7) contain data, and all unused LSbs
contain 0s. Table 4 gives examples of 12-bit resolution output data and the corresponding temperatures.

OPERATIONTHERMOSTAT FUNCTION
The thermostat output (T
OUT
) is updated after every temperature conversion, based on a comparison
between the measured digital temperature and user-defined upper and lower thermostat trip points. T
OUT
remains at the updated value until the next conversion completes. When the measured temperature meets
or exceeds the value stored in the upper trip-point register (T
H
), T
OUT
becomes active and remains active
until the measured temperature falls below the value stored in the lower trip-point register (T
L
) (see
Figure 5). This allows the user to program any amount of hysteresis into the output response. The active
state of T
OUT
is user-programmable through the polarity bit (POL) in the configuration register.
The user-defined values in the T
H
and T
L
registers (see Figure 4) must be in twos complement format
with the MSb (bit 15) containing the sign bit (S). The T
H
and T
L
resolution is determined by the R0 and
R1 bits in the configuration register (see Table 6), so the T
H
and T
L
resolution matches the output
temperature resolution. For example, for 10-bit resolution bits 5 through 0 of the T
H
and T
L
registers read
out as 0 (even if 1s are written to these bits), and the converted temperature is compared to the 10 MSbs
of T
H
and T
L
.
The T
H
and T
L
registers are stored in EEPROM; therefore, they are NV and can be programmed prior to
device installation. Writing to and reading from the T
H
and T
L
registers is achieved using the Access TH
