3.1 Principle

Complimentary outputs with deadband insertion are a common use case for inverter-based applications with half-bridge topologies. Deadband is useful for applications with half-bridge control to avoid shoot-through conditions, such as motor driver or inverter-based applications.

To generate 3 pairs of complementary PWM with deadband insertion, TIMA0 is required for 3 CCP channels. The following is the key feature for the use case.
  • Generate PWM with 3 CCP channels (TIMA0 only)
  • Enable complimentary CCP output channels (TIMA only)
  • Configure deadband insertion (TIMA only)
