Module Control
6.1
Power off and reset limitations
There is no limitations to power off and reset.
6.2
Power supply interrupt
If MAINVCC drops out of range(<3.05V 1usec typ) then the module is completely shut down.
In thie case, please execute power-on sequence.
6.3
Over-temperature Protection
PM8018 provides over-temperature protection. If PM8018 die temperature greater than 150 °C,
the module is completely shut down.
Temperature hysteresis is incorporated such that the die
temperature must cool significantly (<110°C typ) before the module can be powered on again.
When the module bocome under 110°C(typ) and a PWR_N signal is enabled, the module will
power up.
Please execute power-on sequence.
6.4
Over-temperature Protection (restricted RF operation).
The thermistor built into the module (around Power Amplifier) detects the temperature around it.
Based on the detected limited temperature, the module starts or terminates temperature protec-
tion and stop transmit/receive functions to prevent devices to be destructed.
