Description

The IR3221 is a Fully Protected Dual High Side Switch I.C. With two additional Low Side switches (IRL1404), the IR3221 drives and controls the whole H bridge topology. It provides shoot-through protection for each leg, H bridge logic control, soft-start sequence and over-current /over-temp. protections. The signals IN1 and IN2 select the operation modes and the PWM Soft-Start sequence cycles the corresponding active low side switch in order to limit the motor inrush current. By using the recommended part number and the proper cooling, the inner High Side IPS protects the whole H-bridge function. The Soft-Start sequence is programmed by an RC time constant and reset itself automatically.
