 alarm is open-drain, active LOW output which requires an external
pull-up resistor. It functions as a system interrupt or power shutdown.
GND
5
Power supply ground.
ALERT
6
ALERT
 alarm is an open-drain, active LOW output which requires an
external pull-up resistor. It functions as an interrupt indicating that the
temperature of the on-chip or remote diode is above or below programmed
overtemperature or undertemperature thresholds.
SDATA

C-bus bidirectional data line. This is an open-drain output which
requires an external pull-up resistor.
