The IR3220S is a fully protected dual high side switch I.C that

integrates an H–bridge motor controller with two very efficient

high side MOSFETs in a single 20-pin package. The IR3220S

combines with the two low side IRF7484Q MOSFETs as few as

10 external passive components to provide a complete, fully op-

erational and fully protected H-bridge control actuator with for-

ward, reverse, braking and non-braking modes without the need

of a micro-controller.

Functional Description

The high side switches provide the direction capability and the H-

bridge protection. The low side MOSFETs bring the flexibility by

offering the high frequency switching ability. Therefore, crude

start-up of the motor is avoided and replaced by a smooth and

stress-less speed ramp-up.

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.

The IR3220S is a Co-pack IPS product offering very low Rds(on)

and a high level of functionality and protection. Its open architec-

ture and programmability helps the designer to optimize each

motor drive upon the application requirements at a very low cost.

For automotive actuators, the motor is kept shorted even during

the low consumption sleep mode. Shoot-through protection, over-

temperature & over-current shutdowns, self-adaptive dead-time

and PWM circuitries are described in details in the AN 1032

Application Note. A general purpose method to help rating the

soft-start sequence as well as layout and thermal considerations

are also covered. Finally, a 6A DC motor actuator with a PCB

size down to 1 Inch² is suggested in the document.
