N4PI: 0DE: 0
PI/DE
PI:
PRI (Current protection detection)
The current of the power amplifier is detected.
Normal value:
0 to 100 (Reference voltage: 3.3 V=255)
DE: PDET (Sub-trans power detection)
Normal value:
0 to 255 (Reference voltage: 3.3 V=255)
* If PRI and PDET are out of the normal value range, the protection function works to turn off the power.
TH/PL
TH:
THM (Thermo protection detection)
The temperature of the heat sink is detected.
Normal value:
0 to 136 (Reference voltage: 3.3 V=255)
* If THM is out of the normal value range, the protection function works to turn off the power.
PL: PLDET (Power limiter detection)
The output voltage of power amplifier is detected.
