Power down; When high, requires the module to limit
power consumption to 1.5W or below. 2-Wire serial
interface must be functional in the low power mode.
Reset; The falling edge initiates a complete reset of the
module including the 2-wire serial interface, equivalent to a
power cycle.

Absolute Maximum Ratings
Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are
absolute stress ratings only. Functional operation of the device is not implied at these or any other conditions
in excess of those given in the operational sections of the data sheet. Exposure to absolute maximum ratings
for extended periods can adversely affect device reliability.
