Power Sequence
To initialize the FMA1125DC properly, please refer to the Power Sequence below when the power is given initially during boot-up.
If the reset transition time during power on does not follow the time sequence below, the Internal LDO and oscillator would not operate
normally.
The Power Sequence is based on the Power Connection type and is shown in the following example.
Power Connection Type is Case B or Case D
Power Connection Type is Case A, Case C, or Case E
