(Note 1) Derate by 5.5mW/°C when operating above Ta=25°C (mounted in 1-layer 74.2×74.2×1.6mm board with 10.22mm2 surface capper area)
Pd of IC is 0.27W and derate by 2.7mW/°C when operating above Ta=25°C.
Caution: Operating the IC over the absolute maximum ratings may damage the IC. The damage can either be a short circuit between pins or an open circuit
between pins and the internal circuitry. Therefore, it is important to consider circuit protection measures, such as adding a fuse, in case the IC is operated over
the absolute maximum ratings.
