9 Power Supply Recommendations

This device operates from an input voltage supply between 0.9 V and 6 V. This device requires a separate 5-V power supply for analog circuits and gate drive. Use the proper bypass capacitors for both the input supply and the 5-V supply in order to filter noise and to ensure proper device operation.
