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.
