There are two power-up/down options. Choosing which one is required for an application will depend
upon circuitry connected to 2.6-V compliant pins and dual 2.6-V/5-V compliant pins. Power-up/down
option A is required if 2.6-V compliant pins and dual 2.6-V/5-V compliant pins are connected to the 5-V
supply with a pull-up resistor or driven by 5-V logic during power-up/down. In applications for which this
scenario is not true the power-up/down option B may be implemented. Option B is less stringent and easier
to ensure over a variety of applications.
Refer to
The power consumption during power-up/down sequencing will stay below the operating power
consumption specifications when following these guidelines.

The Option A power-up sequence (excluding V
The first step in the sequence is required is due to gate-to-drain stress limits for transistors in the pads of
2.6-V compliant pins and dual 2.6-V/5-V compliant pins. Damage can occur if gate-to-drain voltage
potential is greater than 3.1 V. This is only a concern at power-up/down. The second step in the sequence
is required is due to ESD diodes in the pad logic for dual 2.6-V/5-V compliant pins and 2.6-V pins. The
diodes are forward biased when V

same instant or before both the high voltage and low voltage supplies are powered-up.
