IR3220-Fully Protected H Quad C. Motor Bridge Type
Features • Over Temperature Shutdown • Over Current Shutdown • Limited Soft-Start Process for Inrush Current • ESD Protection • Status Feedback • Sleep Mode
DESCRIPTION The IR 3220 is a fully protected dual high side switch IC with two additional low side switches (like the IRF7474 - 01/01 available), the IR 3220 drives and controls the entire H-bridge topology. It provides thru each leg, H protection bridge logic control, soft start sequence and over current/overtemperature. Protect. The signals IN1 and IN2 select the operating mode and the corresponding sequence of PWM soft-start cycles in order to activate the low-side switches to limit automotive inrush current. High-end IPS protects the full H-bridge function by using the recommended part numbers and proper cooling. The soft-start sequence is programmed by an RC time constant and will automatically reset.
