Power Consumption

This section details the power consumption of the device as measured during various modes of operation. Power dis-

sipation is determined by temperature, supply voltage, and external source/sink requirements.

Note:

The rise time for the 3.3V supply can be extended to 100ms max if RESET_N is actively driven low, typi-

cally by another IC, until 1 μs after all supplies are within operating range.
