IR3220S
FULLY PROTECTED H-BRIDGE FOR D.C. MOTOR
Features
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
Programmable PWM In-rush
Current Limitation (e.g 18A)
6 A Continuous Current Capability
without Heat Sink (2 x 13 m ? )
Over-Temperature (165 °C) and
Over-Current (30A) Protections
20 kHz PWM Oscillator Embedded
Low & High Frequency Switching
Operation (self adaptive dead-time)
stress-less speed ramp-up.
Easy Speed / Torque Control
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.
