• Fixed-Off Time PWM mode
• Current Limit PWM mode
• Current Reset PWM mode

• Enhanced Leading-Edge Blanking (LEB)
• 8 mA PWM pin output drive
The High-Speed PWM module contains up to seven
PWM generators. Each PWM generator provides two
PWM outputs: PWMxH and PWMxL
base generators provide a synchronous signal as a
common time base to synchronize the various PWM
outputs. Each generator can operate independently or
in synchronization with either of the two master time
bases. The individual PWM outputs are available on
the output pins of the device. The input Fault signals
and current-limit signals, when enabled, can monitor
and protect the system by placing the PWM outputs
into a known “safe” state.
Each PWM can generate a trigger to the ADC module
to sample the analog signal at a specific instance dur-
ing the PWM period. In addition, the High-Speed PWM
module also generates two Special Event Triggers to
the ADC module based on the two master time bases.
The High-Speed PWM module can synchronize itself
with an external signal or can act as a synchronizing
source to any external device. The SYNCI1 and
SYNCI2 pins are the input pins, which can synchronize
the High-Speed PWM module with an external signal.
The SYNCO1 and SYNCO2 pins are output pins that
provides a synchronous signal to an external device.
