SHUTDOWN MODE
Shutdown mode is enabled by setting the shutdown bit in the Configuration register via the Serial Bus. Shutdown
mode reduces power supply current to 5 礎(chǔ) typical. T_CRIT_A is reset if previously set. Since conversions are
stopped during shutdown, T_CRIT_A and INT will not be operational. The Serial Bus interface remains active.
Activity on the clock and data lines of the Serial Bus may slightly increase shutdown mode quiescent current.
Registers can be read from and written to in shutdown mode. The LM92 takes milliseconds to respond to the
shutdown command.
INT AND T_CRIT_A OUTPUT
The INT and T_CRIT_A outputs are open-drain outputs and do not have internal pull-ups. A "high" level will not
be observed on these pins until pull-up current is provided from some external source, typically a pull-up resistor.
Choice of resistor value depends on many system factors but, in general, the pull-up resistor should be as large
as possible. This will minimize any errors due to internal heating of the LM92. The maximum resistance of the
pull up, based on LM92 specification for High Level Output Current, to provide a 2 volt high level, is 30K ohms.
FAULT QUEUE
A fault queue of 4 faults is provided to prevent false tripping when the LM92 is used in noisy environments. The 4
faults must occur consecutively to set flags as well as INT and T_CRIT_A outputs. The fault queue is enabled by
setting bit 4 of the Configuration Register high (see CONFIGURATION REGISTER ).
