Fault Multiplexer

In order to allow a flexible way of mapping several fault triggering sources to all the DPWMs channels, the

UCD3138 provides an extensive array of multiplexers that are united under the name Fault Mux module.

The Fault Mux Module supports the following types of mapping between all the sources of fault and all

different fault response mechanism inside each DPWM module.

•

Many fault sources mapped to a single fault response mechanism. For instance an analog comparator

in charge of over voltage protection, a digital comparator in charge of over current protection and an

external digital fault pin can be all mapped to a fault-A signal connected to a single FAULT MODULE

and shut down DPWM1-A.

•

A single fault source can be mapped to many fault response mechanisms inside many DPWM

modules. For instance an analog comparator in charge of over current protection can be mapped to

DPWM-0 through DPWM-3 by way of several fault modules.

•

Many fault sources can be mapped to many fault modules inside many DPWM modules.
