Notes 1.
If the POC circuit detection voltage (V
POC
) is used with 2.85 V
±
0.15 V, then use the products in the voltage
range of 3.0 to 5.5 V.
2.
If the POC circuit detection voltage (V
POC
) is used with 3.5 V
±
0.2 V, then use the products in the voltage
range of 3.7 to 5.5 V.
3.
Select either of the functions of these alternate-function pins.
