PDI-A15-5V1A – SPWM and PWM Driver with Inverted, Push-Pull, and Sinusoidal Mode
PDI-A15-5V1A is a programmable two-channel SPWM and PWM driver module with Inverted, Push-Pull, and Sinusoidal operating modes. It supports 100 Hz – 1 MHz operation in Inverted and Push-Pull modes, and 1 Hz – 250 kHz operation in Sinusoidal mode. The module provides 5 V output signals, 1.5 A peak sink/source current capability, 0.1 Hz frequency resolution, 0.1% duty-cycle resolution, programmable dead-time, configurable signal limits, and SPI communication with selectable logic level from 1.8 V to 5 V.
