The Fault Mux Module provides a multitude of fault protection functions within the UCD3138 high-speed loop
(front end control, filter, DPWM and loop Mux modules). The Fault Mux Module allows highly configurable fault
generation based on digital comparators, high-speed analog comparators and external fault pins. Each of the
fault inputs to the DPWM modules can be configured to one or any combination of the fault events provided in
the Fault Mux Module.
Each one of the DPWM engines has four fault modules. The modules are called CBC fault module, AB fault
module, A fault module and B fault module.
The internal circuitry in all the four fault modules is identical, and the difference between the modules is limited to
the way the modules are attached to the DPWMs.
