4.2.3 Miscellaneous Control Section

There are miscellanous settings that are available on the GUI for easy access (see Figure 4-6).

This device supports parallel bridged-tied load operations. Channels 1 and 2 can be one PBTL channel and channels 3 and 4 can be the other. Before setting the channels to PBTL mode, connect the (+) terminals of channels 1 and 2 and/or channels 3 and 4. Then connect the same channels together for their respective (-) terminals. The device needs to be in standby before reconfiguring the output to PBTL.

The Clip Detect can be set to either disable or enable, with disable being the default setting.

The overcurrent (OC) has four level that can be changed via the drop-down menu in the OC box. The default level is 1.

Overtemperature warning (OTW) can be programed using the pull-down menu to choose the OTW temperature. The default setting is 130°C.

The output switching frequency (FSW) or Pulse Width Modulation (PWM) frequency is set at 2.1 MHz. The pull-down menu on the Frequency box is used to change the PWM to 384kHz, 576kHz, and 2.3MHz.

Another feature this device has is being able to adjust at what THD level the clip detect goes off. The pull-down menu on the Clip Level box allows the user to set the detect threshold to go off at either 1% THD, 2% THD, 3% THD or 10% THD. 1% THD is the default value.

PWM Mode allows the user to choose between a BD modulation scheme or a BDHE/1SPW modulation scheme. BD modulation is the default value.

GPIO 1 and GPIO 2 pull-down menus have the same configuration options but are for their respective pins. Each one can be used to output specific signals or as inputs depending on the setting chosen. The states that can be selected for GPIO 1 and GPIO 2 are the following: Hi-Z, WarningZ, FaultZ, Clip Detect 1, Clip Detect 2, Sync Out, DVDD, GND, Sync In, and Mute Z. WarningZ and FaultZ are the Warning and Fault output signals and the MuteZ setting allows the device to have a hardware control mute pin. Default setting is Hi-Z for both GPIO 1 and GPIO 2.

The final part of the Miscellaneous Controls section is the Fault Pin pull-down menu. This changes the corresponding device fault pin. It can be selected to read out either FaultZ, WarningZ, Clip Detect 1 or Clip Detect 2. FaultZ is the default setting.
