Title: Innovations by Rajsekhar Jayaraman: Pioneering High Voltage Integrated Circuit Drivers

Introduction

Rajsekhar Jayaraman, located in Rancho Palos Verdes, California, is a distinguished inventor with two notable patents to his name. His work primarily focuses on high voltage integrated circuit technology, showcasing innovative designs that enhance the performance and efficiency of electronic devices.

Latest Patents

Among his latest patents, Rajsekhar has developed a high voltage integrated circuit driver for half-bridge circuits. This invention includes a half-bridge driver circuit that features both a lower drive module and a floating upper drive module. These components are designed to effectively drive the respective upper and lower power transistors within a high voltage half-bridge configuration.

The integrated circuit chip incorporates an on-chip bootstrap diode emulator that activates in response to a control signal applied to its gate. This mechanism allows current from the power supply to charge an external bootstrap capacitor, which in turn powers the upper drive module. Notably, the upper drive module is situated within an insulated well, and the diode emulator employs a JFET transistor as its primary current-carrying element. This JFET transistor is synchronized to conduct simultaneously with the lower power transistor, enhancing the circuit's reliability and functionality.

Furthermore, another patent developed by Rajsekhar features a similar high voltage integrated circuit driver but utilizes an LDMOS transistor instead of a JFET. This innovative design also supports the operation of a high voltage half-bridge driver, demonstrating Rajsekhar's versatility in circuit design and his commitment to advancing integrated circuit technology.
