Figure 2-3 Simplified Schematic Illustration of Simplified H-Bridge Mode Output Circuit
In simplified H-bridge mode, the signal at the PCMPWM_i_AL output is the inverted PCMPWM_i_AH
signal.
3. Full H-Bridge Mode
In the full H-bridge mode four outputs per speaker are used. All transistors of the H-bridge have
individual driver outputs. Figure 2-4 depicts the circuit for full H-bridge mode.
Figure 2-4 Simplified Schematic Illustration of Full H-Bridge Mode Output Circuit
In full H-bridge mode the PCMPWM_i_AL signal is again the inverted PCMPWM_i_AH signal whereas
the signal at the PCMPWM_i_BL output is the inverted PCMPWM_i_BH signal. The PCMPWM_i_Ax
output pair is activated for positive PCM data samples. The PCMPWM_i_Bx output pair is activated for
negative PCM data samples. If the PCM data sample is zero, no branch of the H-bridge is activated.
The PCMPWM_i_Ax and PCMPWM_i_Bx branches are never active at the same time.
