Push-Pull PWM Driver

Push-Pull PWM Generator
Push-Pull PWM Generator Banner

The PDI-A14-5V1A is a push-pull pwm driver device with programmable two-channel PWM signal output. It has two signal outputs with equal frequencies whose frequency can be selected between 100 Hz – 1 MHz and pulse widths between 0% – 50.0%. With its high frequency resolution (0.1 Hz) and high duty cycle resolution (0.1%), it is designed for sensitive applications.

The supply voltage of the device is 5 volts. The high voltage level of the signal outputs is 5 volt and the peak sink/source current capacity is 1.5 ampere. Both outputs of the device are designed as Low-Side drivers. This provides flexibility in the choice of isolated half-bridge or full-bridge drive structures to be connected to the outputs of the device.

  • Two Channel Push-Pull PWM Signal Output: 100 Hz – 1 MHz / 0% – 50%

  • High Precision: Frequency: 0.1 Hz and Duty Cycles: 0.1%

  • Frequency and Duty Transitions: Ramp / Sine / Exponential / Logarithmic. Programmable Transition Time: 0 – 600 sec

  • High Peak Current Capability: 1.5A

  • Limitable Signal Parameters.

  • Programmable Device Startup Routine.

  • SPI Communication: up to 20 MHz

  • Selectable SPI Logic Level: 1.8V – 5V
