Latest Patents

One of his latest patents is titled "Circuit and method of current limiting a half-bridge driver." This invention provides a current limit on both the low-side and high-side drivers of a half-bridge driver. The current limits are initially set equal, and if the low-side driver reaches its current limit, a modulation current from the low-side driver increases the high-side driver current limit threshold. This innovation ensures stable operation of the control circuits.

Another significant patent is the "Clamp circuit and method for detecting an activation of same." This clamp circuit is designed to protect a MOSFET from destructive voltages. It includes a clamping element, a Zener diode, two current mirrors, a current switch, a reference current source, and a voltage detector. When the drain voltage of the MOSFET exceeds a clamping voltage, the clamp circuit activates, ensuring the safety and integrity of the MOSFET and its inductive load.
