IRAM256-1067A Series 10A, 600V Integrated Power Module for Appliance Motor Drive Applications Description International Rectifier's IRAM256-1067A is a 10A, 600V Integrated Power Hybrid IC with Open Emitter pins for advanced Appliance Motor Drives applications such as energy efficient Air Conditioner and Washing Machine. IR's technology offers an extremely compact, high performance AC motor-driver in a single isolated package to simplify design. This advanced HIC 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 heatsink.

Electrolytic bus capacitors should be mounted as close to the module bus terminals as possible to reduce ringing and EMI problems. Additional high frequency ceramic capacitor mounted close to the module pins will further improve performance. 2. In order to provide good decoupling between VCC-VSS and VB1,2,3-VS1,2,3 terminals, the capacitors shown connected between these terminals should be located very close to the module pins. Additional high frequency capacitors, typically 0.1µF, are strongly recommended. 3. Value of the boot-strap capacitors depends upon the switching frequency. Their selection should be made based on IR design tip DN 98-2a, application note AN-1044 or Figure 9. Bootstrap capacitor value must be selected to limit the power dissipation of the internal resistor in series with the VCC. (see maximum ratings Table on page 3). 4. After approx. 2ms the FAULT is reset. (see Dynamic Characteristics Table on page 5). 5. PWM generator must be disabled within Fault duration to guarantee shutdown of the system, overcurrent condition must be cleared before resuming operation. 9 www.irf.com © 2014 International Rectifier Submit Datasheet Feedback May 14, 2014 Maxim um Output Phase RMS Current - A IRAM256-1067A 10 V+=320V V+=400V 8 6 4 TC = 90ºC TC = 100ºC TC = 125ºC 2 0 0 2 4 6 8 10 12 14 16 18 20 PWM Sw itching Frequency - kHz Figure 4.
