Commenced mass production of current sensors for EV, highly compatible with SiC/GaN power devices and suitable for chargers and electronic fuses

The high sensitivity characteristics of the compound Hall element deliver a fast response time.

Using this product in chargers and DC/DC converters that use next-generation power devices such as SiC and GaN enables a higher switching frequency, resulting in circuits with smaller board sizes.

It also has a fast response time that can provide all kinds of overcurrent protection, making it possible to introduce safe electronic fuse circuits into automotive power conversion systems.

We have developed a unique package to achieve a low primary conductor resistance of 0.3mΩ. The heat generation is suppressed even under the continuous energization of 40Arms at an ambient temperature of 125ºC, thereby facilitating thermal design.

In addition, the voltage-resistant structure that ensures sufficient creepage and space distances enables the use in high-voltage applications with voltages in excess of 650V.

The use of SiC and GaN power devices significantly impacts the noise environment due to their high voltage and high speed switching.

This product is less likely to affect sensor characteristics even in the environments mentioned above, and can detect current without the influence of noise.
