Absolute maximum ratings indicate sustained limits beyond which damage to the device may occur. All voltage parameters are absolute voltages referenced to AGND and DGND, all currents are defined positive into any lead. The thermal resistance and power dissipation ratings are measured under board mounted and still air conditions.


Description

The IR1110 is a high performance analog IC designed to control ramp rate and voltage of the DC bus from either single or three phase AC line voltage input. It controls a SCR half bridge and provides robust ride through capability in event of transient loss of line, and DC bus regulation with eternal reference input. Comprehensive line status fault output including 1/3 phase loss and high or low line fault provides versatile line diagnostic capability to the system. The IR1110 is based on advanced low power design so it can utilize the SCR snubber derived power supply.
