1) Measured on Micronas typical 2-layer (1s1p) board based on JESD - 51.2 Standard with maximum power consumption allowed for this package
2) A power-optimized board layout is recommended. The Case Operating Temperature mentioned in the "Absolute
Maximum Ratings" must not be exceeded at worst case conditions of the application.
3) Internal regulators used
4) If internal regulators are not used, connect AVDD to AREG0/1.
5) Positive value means current flowing into the circuit.
