TDA4VM-Q1: 满足功能安全目标下的最大POK阈值设定及PLL精度误差

1.满足功能安全目标下的最大POK阈值设定

我们发现在对TAD4VM芯片配置POK阈值且考虑功能安全时，由于要求电压范围与前级电源的输出范围的不同，完全按照当前Datasheet的Recommended Operating Range可能不够或容易触发过欠压警报,但实际上有时可能是没有安全隐患的。

想了解芯片在不损坏的前提下，Recommanded Operating Range外能接受的△V是多少?

2.TDA4VM内部PLL模块的时钟精度/误差是多少？

    1. 请在Recommanded Operating Range范围内以保证芯片的正常工作。
    Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under Section 7.4, Recommended Operating Conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

    2.抱歉，没有这个数据。 只要确保输入时钟满足数据手册的要求。
