HR1002 Overview
The HR1002 is an enhanced LLC controller that provides robust adaptive dead-time adjustment (ADTA) and capacitive mode protection (CMP), as well as improved functional surge performance. ADTA automatically inserts a dead time between the two plimentary gate outputs. This is ensured by keeping the outputs off while sensing the dV/dt current of the half-bridge switching node.
