Power-on and Initialization of Internal Circuit

As for this IC, two systems of supply voltage should be turned on simultaneously. The initialization of the

internal circuit should be also performed by maintaining the system clear pin at low during the specified time

after setting the supply voltage in the range of recommended operating conditions and stabilizing as shown in

the figure below. Keep in mind that the internal circuit may not be initialized correctly if system clear

cancellation is performed before the supply voltage is set in the range of the recommended operating

conditions.
