20A, 600V
Integrated Power Module for
Appliance Motor Drive Applications
Description
International Rectifier's IRAM256-2067A is a 20A, 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.
Features
• Integrated gate drivers and bootstrap diodes
• Temperature monitor
• Protection shutdown pin
• Low VCE (on) Trench IGBT technology
• Undervoltage lockout for all channels
• Matched propagation delay for all channels
• 3.3V Schmitt-triggered input logic
• Cross-conduction prevention logic
• Motor power range up to 1.5kW / 85~253 Vac
• Isolation 2000VRMS min and CTI> 600
• High operating case temperature, TCMAX=125°C

Typical Application Connection IRAM256-2067A
1. 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.
