DESCRIPTION
The Microchip Technology An external microcontroller provides the direction signal and the PWM frequency. In PWM operation, the high-side switches are permanently on, while the low-side switches are activated by the PWM frequency. The ATA6824C also includes a voltage regulator to supply the microcontroller; the output voltage can be set to either 5V or 3.3V via the VMODE input pin.
