Fully Protected H-Bridge For DC Motor In A 20 Lead SOIC Package

Fully Protected H-Bridge for DC Motor in a 20 Lead SOIC package IR3220S The IR3220S features shoot-through protection for each leg, H- bridge Logic control, soft-start sequence and over-current / over- temperature shutdown protections. Two input signals (IN1 & IN2) select the operating modes while the PWM soft-start sequence cycles the corresponding active low side MOSFET in order to limit the motor in-rush current. The soft-start sequence is pro- grammed by an RC time constant and reset itself automatically. Thanks to the inner PWM Oscillator the IR3220S CAN also be the final stage of an overall torque or speed loop. If needed, an external Clock may force the H-bridge switching operation. This CAN be combined with low frequency PWM operation through the IN1(2) inputs. By International Rectifier Corp.
