Note
As the power dissipation of a semiconductor chip is limited its package and ambient temperature,
this device requires a maximum output current be calculated for a given operating condition. The
maximum allowable power consumption (Pd (max)) of this device is calculated as follows:
Pd (max)(Watt) = (Tj (junction temperature) (max) - Ta (ambient temperature) )(°C)
Rth (°C /Watt)
Based on the Pd (max), the maximum allowable current can be calculated as follows:
Iout = ( Pd – VDD‧IDD) / ( # outputs‧Vo‧Duty )
