The integrated buck regulator efficiently converts the battery voltage to a gate driver voltage which can be set to 6.5, 7, or 8 V. This supplies the linear regulator which can provide a noise-free 3.3 or 5 V supply for the digital circuitry and microcontroller. Finally, the integrated low-side and high-side charge pumps provide the gate driver supply voltages which enable duty cycles up to 100%. All of these functions are integrated into a 48-pin VQFN package with an exposed bottom-side thermal pad. This allows a significant reduction of the component count and board size.
