Description
The IR1110 is a high performance analog IC designed
to control ramp rate and voltage of the DC bus from
Typical Application
• Motor drives
• Welders
• Battery chargers
• Power supplies
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
Notes for DC Electrical Characteristics
Note 1) VBREF=5.0V will assure full SCR firing on to produce the maximum amount of DC bus voltage and faster conver-
gence to the maximum DC bus voltage. Although VBREF=4.0V corresponds to the maximum voltage, it will take longer time
to converge to the maximum DC bus voltage.
Note 2) These voltage values are linearly proportional to VLNSET. For example, if VLNSET = 2.0V, then all values are twice
of those values listed in the table.
Note 3) VDD must be regulated within ±2.5%. VSS must be regulated within ±5%.
AC Electrical Characteristics
VDD = 5.1V, VSS, = 5.1V, CL = 1000pF and TA = 25°C unless otherwise specified.
