Description
International Rectifier’s IRAM109-015SD is a multi-chip Hybrid IC developed for low power appliance motor
control applications such as Fans, Pumps, refrigerator compressors, etc. 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 internal shunt resistor saves board
space and provides clean current feedback. The combination of highly efficient high voltage MOSFETs, the
industry benchmark Half-Bridge 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 range 60~250W / 85~253 Vac.
• Integrated Gate Drivers and Bootstrap Diodes.
• Shut-Down input turns off both channels.
• Under-voltage lockout for all switches.
• Matched propagation delay.
• Schmitt-triggered input logic.
• Cross-conduction prevention logic.
• Low di/dt switching for better noise immunity.
• Internal Current Shunt.
• Internal thermistor for temperature feedback.
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 COM.
