Modern power conversion systems must simultaneously become more efficient, smaller, and cheaper than the previous generation. With this in mind, we have begun to utilize our expertise in current and voltage sensing to create aOpen-loop Hall current sensorHMSR。 The traditional current measurement method uses open-loop Hall effect sensors. The magnetic field generated by this current is captured by the magnetic core and the current magnitude is measured by Hall sensor. Recently, dedicated ASICs have helped improve the adoption of advanced compensation technologies in systems.

In the first decade, many domestic and foreign manufacturers adopted LTSR products to achieve miniaturization. After a period of time, the best way to ensure optimal performance is to combine closed-loop Hall effect technology with specially designed closed-loop application specific integrated circuits. The development of these ASICs technology has propelled the advancement of open-loop Hall effect sensors to deliver performance levels close to those of closed-loop technology. Open loop technology not only reduces costs, but it also brings market demand and improves sensor structure, reducing device power consumption. The development of the HLSR series in the past decade not only provides high performance in offset, but also has good time and response for all PCBs. What's even more attractive is that the height is only a few millimeters.
