PRODUCTION DATA
A 3.3-V, 80mA linear regulator is integrated in the DRV8317 and is available to power external circuits. The AVDD regulator is used for powering up the internal circuits of DRV8317 and can also provide power to external circuits like MCU, logic, hall sensors, LEDs for up to 80 mA. The output of the AVDD regulator should be bypassed near the AVDD pin with a X5R or X7R, up to 7.05µF (4.7µF typical), 6.3-V ceramic capacitor routed directly back to the adjacent AGND ground pin.
The AVDD nominal, no-load output voltage is 3.3 V.
Use Equation 1 to calculate the power dissipated in the device by the AVDD linear regulator.
The supply input voltage for AVDD regulator (VIN_AVDD) can be same as VM supply voltage, or lower or higher than VM supply voltage.
