When designing this kind of device, the designer must make sure that the power circuit is efficient and is able to drive the motor to its full potential. The great thing about the 6EDL7141 gate driver is that the designer can configure power outputs in several points, which will surely help in the design. The 6EDL7141 incorporates a complete system power supply architecture. It includes the synchronous DC to DC buck converter, which is capable of supplying up to 300 mA with overcurrent protection. This requires only an external inductor and capacitor. In a nutshell, it provides the low voltage supply to operate the control and gate drive circuitry in the system. Its output voltage is also configurable at 6.5, 7, and 8 V. The output from the buck regulator supplies another component: the low drop-out linear regulator (LDO). It can be set to 3.3 or 5 V to supply the digital circuitry in the system, especially the microcontroller. The linear regulator incorporates overcurrent protection and an overcurrent pre-warning function, which can be communicated to the microcontroller through an open-drain digital output pin. The buck regulator also supplies two charge pumps that will provide the power to the high- and low-side gate drives. Finally, the VDDB is available externally from the buck converter and the DVDD is available externally from the LDO.
