Push-Pull PWM Driver for Dual-Channel Signal Control

PDI-A14-5V1A: Push-Pull PWM Driver

The PDI-A14-5V1A is a push-pull PWM driver designed for programmable two-channel 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%.

With 0.1 Hz frequency resolution and 0.1% duty cycle resolution, the device is suitable for applications where timing accuracy and precise PWM adjustment are important.

The device 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. Both outputs are designed as low-side drivers, providing flexibility when connecting the device to isolated half-bridge or full-bridge driver structures.
