HR1001A - Enhanced LLC Controller

General Description

HR1001A is the OCP auto-recovery version of HR1001B.

Key Features

  • of adaptive dead-time adjustment (ADTA) and capacitive mode protection (CMP). The adaptive dead-time adjustment inserts a dead time between the two complimentary gate outputs automatically. This is ensured by keeping the outputs off while sensing the dv/dt current of the half-bridge switching node. The ADTA features easier design, lower EMI, and higher efficiency. HR1001A incorporates anti-capacitive mode protection, which prevents potentially destructive capacitive mode switching if the output.

The Future of Analog IC Technology DESCRIPTION HR1001A is the OCP auto-recovery version of HR1001B. HR1001A is an enhanced LLC controller, which provides new features of adaptive dead-time adjustment (ADTA) and capacitive mode protection (CMP). The adaptive dead-time adjustment inserts a dead time between the two complimentary gate outputs automatically. This is ensured by keeping the outputs off while sensing the dv/dt current of the half-bridge switching node. The ADTA features easier design, lower EMI, and higher efficiency. HR1001A incorporates anti-capacitive mode protection, which prevents potentially destructive capacitive mode switching if the output is shorted or has a severe overload. This feature protects the MOSFET during abnormal conditions, making the converter robust.
