BA3258 HFP I/O equivalence circuit BA33 Dxx Series I/O equivalence circuit Power Dissipation If the IC is used under excessive power dissipation conditions, the chip temperature will rise, which will have an adverse effect on the electrical characteristics of the IC, such as a reduction in current capability. Furthermore, if the temperature exceeds Tjmax, element deterioration or damage may occur. Implement proper thermal designs to ensure that the power dissipation is within the permissible range in order to prevent instantaneous IC damage resulting from heat and maintain the reliability of the IC for long-term operation.
