4-Channel Phase-Adjustable PWM Generator: PP504F1A-02W40

PP504F1A-02W40: 4-Channel PWM Generator

PP504F1A-02W40 is a PWM-Core module developed for applications that require four programmable PWM signal outputs.

The module operates with a 5–18 V input supply and provides four PWM channels. The frequency, phase and duty cycle parameters of each channel can be configured independently. This structure makes the module useful in applications where multiple PWM signals must be generated with controlled timing relationships.

Phase-Adjustable PWM Signal Control

PP504F1A-02W40 supports a frequency range from 4 Hz to 500 kHz. The phase angle can be adjusted from 0° to 360°, while the duty cycle can be set between 0% and 100%.

This makes the module suitable for motor control tests, switching amplifier circuits, driver experiments and other systems where the timing relationship between PWM channels is important.

UART-Based Configuration

The module is configured through UART commands sent from an external microcontroller or control system. Frequency, phase and duty cycle values can be defined by using the communication structure provided for the PWM-Core interface.

The configured signal values are stored in internal memory. This allows the module to retain its settings after restart and reduces the need for repeated configuration in recurring test or development setups.

Synchronous and Asynchronous Operation

PP504F1A-02W40 supports both synchronous and asynchronous operation modes.

In synchronous mode, the PWM channels operate together, allowing phase relationships to be defined between channels. In asynchronous mode, channels can be updated more independently, which may be useful when phase synchronization between outputs is not required.

Typical Application Areas

PP504F1A-02W40 can be used in systems that require programmable and phase-adjustable PWM signals.

Typical application areas include:

• MOSFET and IGBT switching applications

• H-bridge and half-bridge driver circuits

• Switching amplifier applications

• Motor control applications

• Timer applications

• R, L and/or C load control circuits

• Prototype and development setups

Conclusion

PP504F1A-02W40 is a compact 4-channel PWM generator designed for programmable frequency, phase and duty cycle control. With UART-based configuration, internal memory support, synchronous/asynchronous operation options and phase-adjustable PWM outputs, it provides a practical signal generation platform for embedded control and driver-oriented development applications.
