This paper proposes a voltage source design to operate the Vgs of the power transistor of the motor driver IC at 13V. The voltage source drives the low-side and charges the bootstrap capacitor. At this time, the target voltage is sufficient to drive the Power Transistor even at a low input voltage, and even at a high input voltage, a stable voltage source is generated with low ripple and high efficiency. It is expected to be used in various applications because a constant 13V voltage source is created at a very wide input voltage of 5.5V-50V through a combination of charge pump, regulator, switch, etc.
