POWER SUPPLY SEQUENCE

Note: The power on/off sequence suggestion:

Applications must observe the following sequence when turning the power on or off.

• At power on: First turn on the logic system power (VDD), and then turn on the driver power (VEE).

• At power off: First turn off the driver power (VEE), and then turn off the logic system power (VDD).
