Description
The IR 3220 is a Fully Protected Dual High Side Switch I.C.
With two additional Low Side switches (e.g. IRF7474 - avail-
able 01/01), the IR 3220 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 opera-
tion modes and the PWM Soft-Start sequence cycles the cor-
responding 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.
