ACT41000
Programmable Voltage, Programmable Current, Low Noise
RFPoL Step-Down Voltage Regulator
Protection RFREQ
In normal conditions, the RFREQ Protection is a short-period transition state. Only when the device cannot validate RFREQ
value in the Recommended RFREQ Range, due to a wrong PCB assembly, the device repeats this RFREQ validation forever.
This loop is a sort of dead-lock because the bias block is ready but cannot activate the main-buck due to the unreliable
RFREQ. By repeating this RFREQ checking loop, the device ensures to keep sending an interrupt of the Reg01[4] bit.
This protection is only performed before entering the Bias Ready state and it is not continuously monitoring <Rfreq> after
passing the Bias Ready state.
