IR3721 Power Monitor IC With Analog Output


Posted on Feb 6, 2014

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. By International Rectifier Corp.
