The new product is a 3-channel half-bridge driver IC incorporating 6 DMOSs[2]. It can control a three-phase brushless DC motor easily by turning the DMOS on and off with the input signals from an MCU.

Supplied in a small package, the new product is best suited for applications such as cooling fans with limited mounting space. Safety in driving the motor is enhanced by various circuits such as over current detection, thermal shutdown circuit.

Key Features of the New Product

  1. Shoot-through current protection
    Shoot-through current is prevented by applying the logic circuit that prevents the upper and lower DMOSs of the driver from being turned on simultaneously. This capability removes the responsibility from the microcontroller, thus reducing the load on the MCU.
  2. Small package
    Leadless VQFN package (5mm×5mm×0.9mm) enables the IC to be mounted on a limited mounting space of the applications such as small cooling fans. The thermal radiation pad is attached at the bottom to further enhance the cooling and contribute to improve radiating characteristics.
  3. Abnormality detection functions
    Over current detection, thermal shutdown circuit, and under voltage lockout circuit are incorporated to improve safety in driving motors.

Enterprises have been using both Big Data and virtualization for years. Until recently, however, most enterprises have not combined the two. Big Data's demands for higher levels of performance, the ability to control quality-of-service (QoS), and the ability to adhere to SLAs have kept it on bare metal, apart from the modern data center cloud. With recent technology innovations, we've seen the advantages of bare metal erode to such a degree that the enhanced flexibility and reduced costs that cl...

DevOps theory promotes a culture of continuous improvement built on collaboration, empowerment, systems thinking, and feedback loops. But how do you collaborate effectively across the traditional silos? How can you make decisions without system-wide visibility? How can you see the whole system when it is spread across teams and locations? How do you close feedback loops across teams and activities delivering complex multi-tier, cloud, container, serverless, and/or API-based services?
Today every business relies on software to drive the innovation necessary for a competitive edge in the Application Economy. This is why collaboration between development and operations, or DevOps, has become IT’s number one priority. Whether you are in Dev or Ops, understanding how to implement a DevOps strategy can deliver faster development cycles, improved software quality, reduced deployment times and overall better experiences for your customers.
