The half-bridges can be configured in the chopping mode by enabling the PWM switching on any particular half-bridge or both half-bridges. Each half-bridge can be mapped to any of the 4 PWM channels for which frequency and duty can be controlled independently. User has the flexibility to select the PWM frequency of channels out of 4 settings of 80-Hz, 100-Hz, 200-Hz and 2-kHz. Moreover, duty (8-bit resolution) of the 4 PWM generators can be adjusted independently.
The PWM chopping mode operation is done in five steps as follows and explained in detail below.
