Abstract
A nitride-based bidirectional switching device is provided 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 comprises a nitride-based bidirectional switching element and an adaption module configured for receiving a DO signal and a CO signal from the battery protection controller and generating a main control signal for controlling the bidirectional switching element. By implementing the adaption circuit, the nitride-based bidirectional switching element can work with conventional battery protection controller for battery charging and discharging management. Therefore, a nitride-based battery management system can be realized with higher operation frequency as well as a more compact size.
