IR2233 Reference Design Kit: 3-Phase 460VAC 3HP Motor Drive
Product Description
Fig 1: IRMDAC3 Hardware
The IRMDAC3 Reference Design is a kit of parts that
work together as an evaluation platform for IR2233
three phase motor control IC and IRPT2062A power
1
module. User connects three phase AC, drive signals,
motor and hall sensors to complete the system.
Power hook-up is via terminal blocks and control
signals are made using a single in line header.
How the IR2233 Control IC Adds Value
· Monolithic HVIC Integrates Control and Drive
Yields Compact, Robust, Economical Designs
· Allows Elegant, Convenient System Partition
· Compatible with Short Circuit, Ground Fault and
Over-Temperature Protection Schemes
How the Power Module Adds Value
Integration of All Inverter Power Components;
· Low Parasitic Coupling = High Performance
· Current Sensing Shunts in DC Feed and Return
· Onboard Temperature Sensor
· Easily Mounted Package
· Short Circuit Rated, Ultrafast IGBT Gen #4
· Wide Operating Temperature Range
· Metal Base gives Excellent Thermal Transfer
and Isolation to 2500V RMS
