AKM wafer factory fire - current sensor shutdown - in-situ replacement - [Wekeway]

According to Kyodo News, on October 20th at around 4:45 pm, the AKM wafer factory at the Yagang Manufacturing Plant of Asahi Chemical Microelectronics Co., Ltd. (AKM), a subsidiary of Asahi Chemical Group, caught fire. Due to adverse reactions from firefighters near the fire scene, firefighting work was interrupted on the same day and continued on the 21st. The next day, the manufacturer announced that it would start at 9:30 pm. On the 21st, mainly responsible for manufacturing LSI (Large Scale Integrated Circuit),Current sensor shutdown）The factory was shut down due to a big fire.

According to post disaster assessments by relevant personnel, the products affected this time include:Chips for industries such as audio, home appliances, automotive, and safety control, including audio modules and current sensors, are expected to be discontinued for up to 10 months. So what products are AKM used for current detection? The editor has organized AKM's products.

1. The HW-322B Hall element is a four pin plug-in Hall element produced by AKM Asahi Kasei Corporation in Japan. The HW-322B Hall element belongs to the InSb high-sensitivity linear Hall element and is typically used in closed-loop Hall effect current sensors and current detection.

The HG-302C Hall element belongs to the gallium arsenide constant current source linear Hall element and is typically used in open-loop Hall effect current sensors and current detection.

58彩票AKM is a leading manufacturer of magnetic sensors. Based on years of professional experience, the Hall type current sensor IC was developed by Asahi Kasei. The current personnel use simple open design to achieve miniaturization of chips (the world's smallest size). At the same time, it also has high precision, high signal-to-noise ratio, and fast response (twice the speed of conventional products in the world), close to a closed magnetic sensor. AKM provides the best current detection solution for inverter control, overcurrent detection, power detection, and other applications.
