HR1002GS - Enhanced LLC Controller

This page provides the datasheet information for the HR1002GS, a member of the HR1002 Enhanced LLC Controller family.

Datasheet Summary

Description

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 complimentary gate outputs.

Features

  • include two-level overcurrent protection (OCP) with external latched shutdown, auto-recovery, brown-in and brownout, capacitive mode protection (CMP), and over-temperature protection (OTP). The HR1002 requires minimal external components, and is available in an SOIC-16 package.

HR1002 Enhanced LLC Controller with Robust Adaptive Dead-Time Adjustment DESCRIPTION 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 complimentary gate outputs. This is ensured by keeping the outputs off while sensing the dV/dt current of the half-bridge switching node. ADTA simplifies the design and provides lower EMI, as well as higher efficiency. The HR1002 incorporates capacitive mode protection, which prevents potentially destructive capacitive mode switching if the output is shorted or is severely overloaded.
