TIDUF36A May 2023 – December 2023 DRV8328
DRV8328C takes an 18-V input voltage and generates 3.3 V and is designed to deliver an average current of 80 mA. Figure 4-2 shows the voltage ripple on the 3.3-V line at a load current of about < 10 mA. The ripple is less than 10 mV, and is assumed to be enough for the MCU ADC pin voltage reference for back EMF sensing and current sensing.
