Digital temperature sensor with overtemperature alarms
8. Local LOW setpoint (LLS) and Remote LOW temperature setpoints (RLSHB) at 0 癈.
9. Conversion Rate register (CR) is set to 8h; the default value of about 16
conversions/s.
7.5 Starting conversion
Upon POR, the RUN/STOP bit 6 of the configuration register is zero (default condition),
then, the device enters into its free-running operation mode in which the device A/D
converter is enabled and the measurement function is activated. In this mode, the device
cycles the measurements of the local and remote temperature automatically and
periodically. The conversion rate is defined by the programmable conversion rate stored in
the conversion rate register. It also performs comparison between readings and limits of
the temperature in order to set the flags and interruption accordingly at the end of every
conversion. Measured values are stored in the temp registers, results of the limit
comparisons are reflected by the status of the flag bits in the status register and the
interruption is reflected by the logical level of the ALERT
and T_CRIT
output. If the
power-on temperature limit is not suitable, the temp limit values could be written into the
limit registers during the busy-conversion duration of about 38 ms of the first conversion
after power-up. Otherwise, the status register must be read and the configuration bit 7
must be reset in order to recover the device from interruption caused by the undesired
temp limits.
7.6 Low power software standby mode
The device can be placed in a software standby mode by setting the RUN/STOP bit 6 in
the configuration register HIGH (logic 1). In standby, the free-running oscillator is stopped,
the supply current is less than 10 mA if there is no SMBus activity, all data in the registers
is retained. However, the SMBus is still active and reading and writing registers can still be
performed. A one-shot command initiates a single conversion which has the same effect
as any conversion that occurs when the device is in its free-running mode. To restore the
device to free running mode, set the RUN/STOP bit 6 LOW (logic 0).
7.7 Temperature data format
The temperature data can only be read from the Local and Remote Temperature
registers; the setpoint registers (for example, T_CRIT, LOW, HIGH) are read/write.
Both local and remote temperature reading data is represented by an 11-bit,
twos complement word with the Least Significant Bit (LSB) = 0.125 癈. The temperature
setpoint data for the remote channel is also represented by an 11-bit, twos complement
word with the LSB = 0.125 癈. The temperature setpoint data for both the local channel
and the T_CRIT setpoints are represented by 8-bit, twos complement words with the
LSB =1.0 癈. For 11-bit temp data, the data format is a left justified, 16-bit word available
in two 8-bit registers (high byte and low byte). For 8-bit temp data, the data is available in
a single 8-bit register (high byte only).
