either single or three phase AC line voltage input. It con- Package
trols 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 capa-
bility to the system. The IR1110 is based on advanced
low power design so it can utilize the SCR snubber
derived power supply.

ADVANCE INFORMATION
Absolute Maximum Ratings
Absolute maximum ratings indicate sustained limits beyond which damage to the device may occur. All voltage param-
eters 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.
