Shutdown
Power up default is with all bits “0” (zero).
D0: Shutdown: When set to 1 the LM75 goes to low power
shutdown mode.
D1: Comparator/Interrupt mode: 0 is Comparator mode, 1 is
Interrupt mode.
D2: O.S. Polarity: 0 is active low, 1 is active high. O.S. is an
open-drain output under all conditions.
D3–D4: Fault Queue: Number of faults necessary to detect
before setting O.S. output to avoid false tripping due to
noise. Faults are determind at the end of a conversion.
Conversions take about 100 ms, typically, to complete.
