At this year’s PCIM Europe – the leading trade fair for power electronics in Nuremberg, Germany (June 11th – 13th) – Alps Alpine will be presenting a wide range of sensors, sensor modules and ICs developed for the automotive, healthcare, industrial, environmental and energy markets in Hall 5, booth 423.
Current Sensor ICs and integrated modules
Alps Alpine has effectively leveraged the know-how and technology acquired from developing various types of sensors to bring current sensors for battery-powered electric vehicles (BEVs) to market. By using innovative magneto-resistive technology, it is possible to measure current without using a magnetic flux concentrator, which is required in other designs. The result is a compact product that increases design freedom when integrated into traction inverters or the battery of an electric vehicle and improves energy efficiency, thus contributing to decarbonization.
Magnetic Sensor ICs
Magnetic sensors are devices that detect the size, direction and degree of change in the magnetism and geomagnetism that is emitted by magnets and currents and convert that into electrical signals. The small-sized magnetic sensors from Alps Alpine are made using the proprietary technology that the company has developed across many years of experience and are at use in a wide range of applications such as in contactless switches, as well as angle and direction detection.
Capacitive Sensor ICs
Alps Alpine has developed the HSLCMB series ICs that incorporate a capacitance measurement circuit and 32-bit CPU. The device enables capacitive sensing with higher sensitivity and noise immunity than conventional products from Alps Alpine. The HSLCMB series is applicable to wide range of applications, including touchless operation, automotive touch screens and liquid level sensors. The device is specified for an operating voltage of 4.75V to 5.5V, an operating temperature range of –40 to +105°C and consumes 14.5mA in operation (21µA in standby). The 48-pin QFN package in which the IC is supplied measures 6,00 mm x 6,00 mm x 0.9 mm.
