Title: Innovations of Lap Chi David Leung

Introduction

Lap Chi David Leung is a notable inventor based in Hong Kong, CN. He has made significant contributions to the field of motor driver circuits, showcasing his expertise through his innovative patent. His work is recognized for its practical applications in enhancing motor control systems.

Latest Patents

One of his key patents is titled "Bootstrapped high-side driver control without static DC current for driving a motor bridge circuit." This invention presents a motor driver circuit designed to drive the gate node of a high-side driver transistor to a boosted voltage from a charge pump while drawing little or no static current from the charge pump. The circuit employs a p-channel pullup-control transistor, which is driven by p-channel transistors pumped by capacitors that prevent current flow to ground from the charge pump. Additionally, an n-channel output-shorting transistor is utilized to short the gate node to the output when the high-side driver is turned off. A coupling capacitor initializes the shorting transistor for each output transition, while a p-channel output-sensing transistor generates feedback to a second stage that drives the coupling capacitor. The voltage on the coupling capacitor is controlled by p-channel diode transistors and an n-channel equalizing transistor.
