40 between them is found in the default power-on behaviour of the chips. While the
43 chip's alarms are active on low. It is important to note that the chips can be
45 configuration register. From here on, we will refer to all these chips as
52 hysteresis value: -40 and -30 degrees for under temperature alarm and +100 and
64 a read operation is performed on the configuration/status register (max or min
68 set again if the temperature rises above TH, and so on. The same logic applies
77 The conversions can be manual with the one-shot functionality and automatic with
78 a set frequency. When powered on, the chip measures temperatures with 1 conv/s.
83 - 64000 (ms) = 1 conv/64 sec
84 - 32000 (ms) = 1 conv/32 sec
85 - 16000 (ms) = 1 conv/16 sec
86 - 4000 (ms) = 1 conv/4 sec
87 - 1000 (ms) = 1 conv/sec (default)
88 - 250 (ms) = 4 conv/sec
89 - 125 (ms) = 8 conv/sec
92 the conversion frequency to 1 conv/s. The conversion time varies depending on
95 The conversion time doubles with every bit of increased resolution. The
98 - 8 bit -> 8.75 ms conversion time
99 - 9 bit -> 17.5 ms conversion time
100 - 10 bit -> 35 ms conversion time
101 - 12 bit (default) -> 140 ms conversion time
104 input temperature in milli-degrees C.
106 - 1000 mC -> 8 bit
107 - 500 mC -> 9 bit
108 - 250 mC -> 10 bit
109 - 62 mC -> 12 bit (default) - actually this is 62.5, but the fil returns 62
111 When chip is in shutdown mode and a read operation is requested, one-shot is
112 triggered, the device waits for <conversion time> ms, and only after that is
117 the temperatures are displayed in milli-degrees. This means, that some data is
119 in the writing of alarm values too. For positive numbers the user-input value
121 the user-input will always be rounded up to the nearest possible value.
123 Bus timeout resets the I2C-compatible interface when SCL is low for more than
124 30ms (nominal).
127 behavior for both settings is dependent on the Fault Queue setting. The ALARM
128 pin is an open-drain output and requires a pullup resistor to operate.
