Analog Devices Inc. ADUM7223ACCZ

The ADUM7223ACCZ is a state-of-the-art, isolated precision half-bridge driver manufactured by Analog Devices Inc., a leader in high-performance analog, mixed-signal, and digital signal processing integrated circuits. This component is designed to provide reliable and robust performance for a variety of applications that require precise control of half-bridge circuits, such as motor control, power supply units, and inverter systems.

Featuring Analog Devices' iCoupler® technology, the ADUM7223ACCZ offers superior isolation capabilities. This technology utilizes magnetic coupling to achieve isolation, ensuring that signals are transferred accurately across the isolation barrier while protecting the low-voltage side from high-voltage transients. The device is capable of providing an isolation voltage of 2.5 kVrms for 1 minute, making it suitable for applications that demand high isolation safety requirements.

The ADUM7223ACCZ is notable for its high integration, incorporating two independent channels, each capable of driving a N-channel MOSFET or IGBT. The driver operates with an input supply voltage ranging from 3 V to 5.5 V, making it compatible with a wide range of logic levels. Furthermore, the output drivers are capable of producing a gate drive voltage of up to 15 V, with a peak output current of 4 A, ensuring that connected power switches are driven effectively for optimal performance.

Designed with precision in mind, the ADUM7223ACCZ boasts a propagation delay of typically 50 ns with a tight timing match between the channels. This precision timing is crucial for applications that require synchronous switching to minimize power losses and improve efficiency. Additionally, the device includes UVLO (Under Voltage Lock Out) protection to ensure that the gates of the power switches are not driven unless there is sufficient voltage to do so safely.

The ADUM7223ACCZ comes in a compact, surface-mount, 16-lead SOIC package, which is conducive to space-constrained applications. Its operating temperature range from -40°C to +125°C ensures reliable performance across a broad spectrum of environmental conditions.

Overall, the ADUM7223ACCZ from Analog Devices Inc. represents a blend of performance, integration, and reliability, making it an excellent choice for designers seeking a high-quality, isolated half-bridge driver for their demanding applications.
