D2R: PDI-A14-5V1A PWM Driver Interface

PDI-A14-5V1A: PWM Driver Interface Design

PDI-A14-5V1A is a programmable PWM driver interface designed for two-channel push-pull PWM signal generation. It provides two signal outputs operating at the same frequency, with an adjustable frequency range from 100 Hz to 1 MHz and a duty cycle range from 0% to 50.0%.

This Design to Reality view presents the transition from the design stage to the manufactured hardware, showing how the compact driver structure, output interface and PCB layout are carried into the final module form.

Push-Pull PWM Signal Generation

The module is intended for applications where timing accuracy and controlled PWM signal generation are important. With 0.1 Hz frequency resolution and 0.1% duty cycle resolution, the output parameters can be adjusted with fine control.

Both outputs operate as low-side drivers. This structure provides flexibility when the module is connected to isolated half-bridge or full-bridge driver configurations.

Electrical Structure and Output Capability

PDI-A14-5V1A operates with a 5 V supply voltage. The high-level voltage of the signal outputs is 5 V, and the outputs support up to 1.5 A peak sink/source current capability.

This output structure makes the module suitable for driver-oriented test setups, switching control applications and systems where a compact two-channel PWM signal source is required.
