Abstract
Systems and methods for a GaN-based motor drive circuit using synchronous rectification is disclosed. In one aspect, a method of operating a motor drive circuit includes providing a half-bridge circuit including a high-side GaN switch and a low-side GaN switch coupled in series at an output node, providing a motor coupled to the output node, turning on the high-side GaN switch such that a first current flows through the motor, turning off the high-side GaN switch, turning on the low-side GaN switch when a voltage at the output node drops below a predetermined threshold voltage, sensing, using a sense device coupled to the low-side GaN switch, a magnitude of a second current that flows through the low-side GaN switch, and turning off the low-side GaN switch when the magnitude of the second current drops below a predetermined threshold current.
