Latest Patents

One of her latest patents is a current sense shunt resistor circuit. This innovation allows for the sensing of current through a wire using a shunt resistor and a sense resistor in a current divider circuit. The values of these resistors are related to provide a specified gain ratio, which enhances the dynamic range of current measurement. The sense resistor is designed to be trimmable, with its configuration discernible from a look-up table based on the required precision for current measurement. Additionally, the two resistors can be related by thermal coefficients to improve the linearity of current measurements.

Another notable patent is a half-bridge high voltage gate driver that provides protection for transistors. This integrated circuit is designed for switching power transistors using an external controller. It features low quiescent current and utilizes a bootstrap supply technique for providing the logic supply voltage. The gate driver integrated circuit is capable of detecting power transistor desaturation, thereby protecting the transistor from transient overvoltages through a smooth shutdown sequence. Furthermore, a fault control circuit within the gate driver manages supply under-voltage and transistor desaturation protection, and it can communicate with multiple gate driver integrated circuits in a multi-phase system via a dedicated local network.
