ADUM7223ACCZ-RL7 Typical application Circuitry

ADUM7223ACCZ-RL7

The ADuM7223ACCZ-RL7 is a model within the ADuM7223 series, which encompasses high-performance, isolated, half-bridge gate drivers utilizing Analog Devices' proprietary iCoupler® technology. This technology ensures effective galvanic isolation between the input control side and the high-power output side, making these drivers ideal for applications in motor control, power conversion, and other systems that require reliable isolation and efficient switching. The "RL7" designation indicates that this model is supplied in a 7-inch diameter reel, suitable for automated assembly processes.

1. Primary Side Power Supply (VDD1, GND1): The ADuM7223ACCZ-RL7 requires a power supply for the input side, connected to the VDD1 pin, with a typical voltage range of 3.0V to 5.5V. The GND1 pin serves as the primary side circuitry's ground. Stable and noise-free power is essential for accurate operation, necessitating decoupling capacitors near the VDD1 and GND1 pins.

2. Secondary Side Power Supply (VDD2, GND2): The isolated output side also needs a separate power supply, connected to the VDD2 pin, within the same voltage range as VDD1. The ground for the output side is connected to the GND2 pin. Decoupling capacitors should also be used here to ensure a clean power supply for the isolated side.

3. Input Control Signals (INA, INB): The device features two input control pins, INA and INB, which accept TTL or CMOS logic signals. These inputs control the switching state of the isolated gate drivers on the output side. The signals should be free from noise and distortion for precise gate control.

4. Isolated Gate Drive Outputs (OUTA, OUTB): The ADuM7223ACCZ-RL7 provides two high-side gate drive outputs, OUTA and OUTB, designed to connect directly to the gates of power transistors like IGBTs or MOSFETs in a half-bridge configuration. The layout should minimize trace inductance to ensure fast and clean switching.

5. Dead-Time Control (DT): The device includes a dead-time control feature via the DT pin, which prevents simultaneous conduction of both high-side and low-side transistors in a half-bridge, avoiding shoot-through. A resistor connected to this pin sets the dead-time duration.

6. Fault and Ready Outputs (FLT, RDY): The FLT pin provides a fault indication, typically for under-voltage lockout conditions, while the RDY pin indicates when the device is ready and operational. These pins can be used for system monitoring and diagnostics.

7. PCB Layout Recommendations: The PCB layout is critical, especially to maintain isolation between the input and output sides and to minimize parasitic inductance in the gate drive paths. Adequate clearance and creepage distances must be observed to ensure safety and reliability.

8. Thermal Management: Proper thermal management may be required, depending on the switching frequency and load conditions. Maintaining optimal performance and lifetime of the gadget can be facilitated by ensuring enough heat conduction away from it.

In summary, integrating the ADuM7223ACCZ-RL7 into a system involves careful attention to the power supply for both the primary and secondary sides, accurate and noise-free input signal routing, strategic gate drive output connections, and dead-time control, along with thoughtful PCB design to uphold signal integrity, isolation, and thermal management. Following these guidelines allows for effective utilization of the ADuM7223ACCZ-RL7 in various applications where isolated gate driving is crucial.
