3 Controlling ATOM Devices

Fault-Based Muting

Fault-based muting automatically mutes the device if one of three faults is detected on
the ATOM Series BUC or SSPA. A PLL Fault, a Power Fault, and an Over Temperature
Fault can all trigger automatic muting. These faults will only mute the device, however, if
the appropriate Mute On Fault software parameter is set to 1. If the appropriate Mute On
Fault parameter is set to 0 then the device will not be automatically muted if the fault is
detected on the device. By default, all Mute On Fault parameters are set to 1.

Most devices use a single parameter (labelled Mute On Faults) to control the muting
behavior for the three detectable faults. Some 100 W devices (running firmware version
1.1.0.1 or higher) have the ability to configure the mute behavior for each of the three
faults individually. ATOMControl will automatically detect whether the connected device
can use the individual settings and will enable or disable the individual Mute On Fault
controls appropriately.

Note that if the device does support the individual Mute On Fault controls, the Mute On
Faults
parameter will be set to 1 if any of the individual Mute On Fault settings are set to
1.

Table 5 below shows the interaction of the standard fault-based muting parameters:
