IR3220S Product Details

General Description
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 operational and fully protected H-bridge control actuator with forward, 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 Hbridge 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, Hbridge logic control, soft-start sequence and over-current / overtemperature 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 programmed 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 architecture 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, overtemperature & 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.
• Programmable PWM In-rush Current Limitation (e.g 18A)
• 6 A Continuous Current Capability without Heat Sink (2 x 13 mΩ)
• Over-Temperature (165 °C) and Over-Current (30A) Protections
• 20 kHz PWM Oscillator Embedded Low & High Frequency Switching
• Operation (self adaptive dead-time) 
• Easy Speed / Torque Control (analog duty cycle input)
• Braking / Non-Braking Modes
• Sleep Mode (braking) for Automotive Actuator
