IR3221 Product details

Description

Packages 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 curSIP 15 TO220 -
