IRAM336-025SB
Series
Integrated Power Hybrid IC for
Appliance Motor Drive Applications
3 Phase Inverter HIC
2A, 500V
Description
International Rectifier’s IRAM336-025SB is a multi-chip Hybrid IC developed for low power appliance motor
control applications such as Fans, Pumps, and refrigerator compressors. The compact Single in line (SIP-S)
package minimizes PCB space.
Several built-in protection features such as temperature feedback, shoot through prevention, under voltage
lockout, and shutdown input makes this a very robust solution. The combination of highly efficient high
voltage MOSFETs and the industry benchmark 3-phase HVIC driver (3.3V/5V input compatible) and
thermally enhanced package makes this a highly competitive solution.
The bootstrapped power supplies for the high side drivers can be generated using internal bootstrap diodes
eliminating the need for isolated power supplies. This feature reduces the component count, board space,
and cost of the system.
Features
• Motor Power up to 250W / 85~253 Vac.
• Integrated Gate Drivers and Bootstrap Diodes.
• Over-current Shut-Down function.
• Under-voltage lockout for all switches.
• Matched propagation delay for all channels.
• Schmitt-triggered input logic.
• Cross-conduction prevention logic.
• Lower di/dt gate driver for better noise immunity.
Absolute Maximum Ratings
Absolute maximum ratings indicate sustained limits beyond which damage to the device may occur. All voltage
parameters are absolute voltages referenced to VSS.

Note 3: The shaded area indicates that both high-side and low-side switches are off and therefore the half-
bridge output voltage would be determined by the direction of current flow in the load.
