International Rectifier – iMOTION™: Second Generation IPM Family Shrinks and Simplifies Appliance Motor Drive Design

IR_July2014_pg9IR-logo
The new IR second generation (Gen2) family of IRAM System-In-Package (SIP) Intelligent Power Modules (IPMs) shrinks and simplifies the design of appliance motor drives.

The IRAM256-1067A (10A), -1567A (15A) and -2067A (20A) are 600V IPMs with Open Emitter pins for advanced appliance motor drives applications such as energy efficient air conditioner, fans, compressors and washing machines. IR’s technology offers an extremely compact, high performance AC motor-driver in a single isolated package to simplify design.

This advanced IPM is a combination of IR’s low VCE(ON) Trench IGBT technology and the industry benchmark 3-phase high voltage, high speed driver (3.3V compatible) in a fully isolated thermally enhanced package. A built-in high precision temperature monitor and over-current protection feature, along with the short circuit rated IGBTs and integrated under-voltage lockout function, deliver high level of protection and fail-safe operation. Using a single in line package with full transfer mold structure and CTI>600 minimizes PCB space and resolves isolation problems to heat-sink.

The new modules are an addition to IR’s iMOTION™ design platform which integrates digital, analog and power technologies together in a flexible, mixed signal chipset to simplify motor control designs and bring energy efficient, cost effective solutions to market faster.
