Typical Application Examples
These examples show functional circuit examples of
typical applications using the D2-24044 device. (Note:
These examples are provided to show typical applications
only and are not intended to represent complete
production-qualified reference designs.)
2-Channel Full Bridge Example
This example (Figure 15) uses configuration mode “01”
to provide two full-bridge loudspeaker output channels.
The PWM controller provides input into four PWM input
pins.
