Apparatus and method for power amplifier surge protection

A method of performing surge protection of a wireless device, the method comprising:

• determining, by a power management integrated circuit, an operating mode of the wireless device, the power management integrated circuit including a boost converter configured to supply a first voltage to a power amplifier of a power amplifier module;
• determining a first overvoltage protection threshold of a charge-pump circuit based at least in part on the operating mode of the wireless device, the charge-pump circuit configured to supply a second voltage to a power amplifier controller of the power amplifier module;
• determining a first input voltage supplied to the power management integrated circuit of the wireless device at a first time period;
• determining that the first input voltage exceeds the first overvoltage protection threshold;
• configuring the charge-pump circuit with a surge-protection configuration responsive to determining that the first input voltage exceeds the first overvoltage protection threshold;
• determining a second overvoltage protection threshold of a charge-pump circuit based at least in part on the operating mode of the wireless device;
• determining a second input voltage supplied to the power management integrated circuit of the wireless device at a second time period that is later than the first time period;
• determining that the second input voltage does not exceed the second overvoltage protection threshold;
• and
• configuring the charge-pump circuit with a non-surge-protection configuration responsive to determining that the second input voltage does not exceed the second overvoltage protection threshold.
