Title:
NITRIDE-BASED BIDIRECTIONAL SWITCHING DEVICE AND METHOD FOR MANUFACTURING THE SAME
Document Type and Number:
WIPO Patent Application WO/2023/123363
Kind Code:
A1
Abstract:
A nitride-based bidirectional switching device is for working with a battery protection controller having a power input terminal, a discharge over-current protection (DO) terminal, a charge over-current protection (CO) terminal, a voltage monitoring (VM) terminal and a ground terminal. The nitride-based bidirectional switching device includes a dual gate transistor. The dual gate transistor includes a first and a second source electrodes and a first and a second gate structures. The first source electrode is configured for electrically connecting to a ground terminal of the battery protection controller. The second source electrode is configured for connecting to the VM terminal of the controller through a voltage monitoring resistor. The first gate structure is configured for electrically connecting to the DO terminal of the battery protection controller. The second gate structure is configured for electrically connecting to the CO terminal of the battery protection controller.
