The High Resolution PWM (HRP) provides two complementary outputs for controlling a half bridge in a light ballast application. It uses a dithering control method to provide a high step resolution (< 4 ns) from an 8 MHz input clock when driving inductive loads. It also provides a shutdown input to disable the outputs when a fault condition is detected in the application.

Features of the HRP include the following:

• One complementary output pair for driving a half bridge
• Frequency or duty cycle dithering between two frequencies for increased output resolution
• Automatic calculation of second frequency for output dithering
• Variable frequency mode with automatic 50% duty cycle calculation
• Variable duty cycle mode
• Programmable dead time insertion
• Shutdown input for fast disabling of outputs

Peripheral Initialization Components provide a low-level hardware approach to initialize registers of the peripheral module. They are intended for experienced users.
