IRLR2905Z The Power Management Leader

International Rectifier is a pioneer and world leader in advanced power management technology, from digital, analog, and mixed-signal ICs to advanced circuit devices and components. Technological breakthroughs from IR are setting the pace for innovation in the electronics we rely on daily.

The cutting-edge computers, lighting, appliances, autos, satellites, and defense systems of today are made possible by IR’s power management technology, which is also paving the way for tomorrow’s innovations in our factories, cars, homes, and offices, as well as in space.

Features

• Channel that is floating up to 1200V.
• A unified integration.
• linear feedback of the current through a shunt resistor.
• Easy interface with direct digital PWM output.
• Easy interface with direct analog output (only for IR2177 and IR2277).
• Independent, quick trip signal for overcurrent.
• high resistance to common mode noise.
• IGBT short circuit condition input overvoltage protection.
• discharges from open drains.

Current Sensing Motion Control ICs.

Monolithic current sensing ICs with the model numbers IR217x and IR227x are intended for motor drive applications. The ICs use an external shunt resistor to sense the motor phase current, transform the information from an analog to a digital signal, and send the signal to the low-voltage circuitry. Implementing IR’s patented high-voltage isolation technology makes the high-bandwidth signal processing possible.

In applications using an A/D interface, the output format is either a discrete PWM to be utilized when one is unavailable or an accurate analog signal connected to an external voltage reference to ease signal conditioning. The separate over-current trip signal makes safeguarding IGBTs from short circuits and overcurrents easier. It is simple for any interface from 3.3V to 15V, thanks to the open-drain digital outputs of the IR2175, IR2177, IR2277, IR21771, and IR22771 devices. It is simple to interface an AD converter with any input range between 3V and 12.5V, thanks to the self-adaptable analog output of the IR2177 and IR2277.

IR’s iMOTIONTM Integrated provides everything you need to create a comprehensive variable speed motor control subsystem create Platform. Powerful digital, analog, and power silicon are combined with algorithms, development software, and design tools in iMOTION, which extends from the front panel and power entrance to the motor terminals.

IR’s iMOTION Integrated Design Platform

IR’s iMOTION Integrated provides everything you need to create a comprehensive variable speed motor control subsystem create Platform. Powerful digital, analog, and power silicon are combined with algorithms, development software, and design tools in iMOTION, which extends from the front panel and power entrance to the motor terminals. New technologies like the embedded microcontroller, Analog Signal EngineTM, and Motion Control EngineTM have been incorporated into the most recent iMOTION digital control ICs to provide simultaneous sensorless control of two Permanent Magnet motors and Power Factor Correction (PFC).

HVIC Backround Information

• An input signal from a control IC is amplified by high-voltage integrated circuit drivers, which then use this signal to drive one or more switches (MOSFETs or IGBTs).
• Many power conditioning applications (e.g., lighting, motor control, etc.) require one or more devices to be switched between high-voltage rails. These applications require some form of high-voltage level-shifting technology.
• International Rectifier’s proprietary high voltage level-shifting technology provides the required level-shifting for these applications in a compact, robust, and cost-effective design.

High Voltage Gate Driver ICs (HVICs)

The MOSFET and IGBT gate driver ICs from International Rectifier is the most straightforward, cost-effective, and compact way to drive MOSFETs or IGBTs up to 1200V in applications up to 12kW. They are also smaller and more compact than a standalone optocoupler or transformer-based solution. They can save over 30% in part count in a 50% smaller PCB area. IR gate driver ICs offer comprehensive functionality with quick switching speeds, built-in robustness, and low power dissipation with only a few external components.

The current and voltage required to switch MOSFETs or IGBTs on and off are produced by gate driver ICs from the logic output of a DSP, microcontroller, or other logic device. Typically, a 3.3-volt logic-level signal is used as the input. All IR gate driver ICs support CMOS, and most also support TTL. The maximum output current is 2A.

Design Simplified by IR Gate Driver ICs with the gate voltage being referenced to the source rather than to ground, driving a MOSFET or IGBT in the high side position of a half-bridge topology or 3-phase inverter leg presents an additional problem. The source voltage is a floating-point value for motor drive, lighting, or SMPS applications up to the maximum bus voltage or voltage rating of the MOSFET or IGBT, 600V and up. The only products on the market with a 1200 V rating for high voltage applications are IR gate drivers, which employ a special level shifter method.

LED Lighting Solution 3

LEDs are very popular because of their long lifespan, low maintenance needs, compact size, design flexibility, ability to create aesthetic effects, safe, low DC voltage operation, outstanding cold weather performance, lack of mercury, superior color gamut, and brightness. IR provides specialized control ICs that can utilize all of the LEDs’ features to the fullest extent, either directly offline or in a DC-DC setting. Additionally, IR ICs provide a high level of integration, reducing the time needed for design and boosting system reliability.

The World’s First Halogen Converter IC

The self-oscillating solution already on the market and the intense cost pressure have also made the halogen market sector difficult. An IC-based solution can be utilized in this sector with the appropriate technology. Reliability and performance problems severely hurt this market. Due to overload and short-circuit fault situations, electronic transformers regularly sustain damage. Furthermore, they must be able to dim the halogen lamps using a typical phase-cutting triac wall dimmer in a smooth and continuous manner.

Offering extensive protection features, light voltage management, and dimming in a single 8-pin IC is a problem. The resulting IR2161 halogen solution has a sleek and simple design that performs better with fewer components overall. Adopting an IC + MOSFET solution will greatly improve these products’ manufacturability and reliability and contribute to the continued expansion of this market segment.

HID Lighting Solutions

HID lights are becoming increasingly well-liked in the industrial sector because of their distinct benefits over other light sources. IR ICs offer a high degree of integration, reducing the required design time and boosting ballast reliability, whether the power is a few tens of watts for shop lights or several hundred for street lighting. The conventional industrial topology comprises a PFC front-end, a buck converter to control the current, and a full-bridge switching device with 50% polarity inversion.

In conclusion, International Rectifier (IR) is a prominent innovator in cutting-edge power management technology and a leader in the electronics sector’s innovation. IR offers state-of-the-art solutions for today’s and tomorrow’s electronics demands, including power systems, components, and digital, analog, and mixed-signal ICs.
