Diodes introduces its first series of advanced InSb Hall element sensors for rotation speed detection and current measurement in consumer applications such as laptops, mobile phones, joysticks, and motors found in various home appliances. In industrial applications, they are designed for use in position encoders and commutation of brushless motors and fans.
The AHE300 is an InSb (ultra-high sensitivity) Hall element with an output voltage of 370mV (max).
The AHE300 is a device that operates even in weak magnetic fields due to its ultra-high sensitivity.
They come in a classic SIP-4 (Type MA) package and are totally lead-free and fully RoHS compliant . Additionally, these sensors are halogen and antimony-free, making them a “green” device . For automotive applications requiring specific change control AEC-Q100/101/104/200, PPAP capable, and manufactured in IATF 16949 certified facilitiesThe reliability tests for these sensors include high temperature storage, heat cycling, high temperature humidity storage, resistance to hand soldering heat, and high temperature operating conditions. Specifically, the high temperature storage test is conducted at 150 ± 10°C for 1000 hours. The heat cycle test involves cycling the temperature between -55°C and +150°C, with 30-minute intervals at each extreme. The high temperature humidity storage test is performed at 85 ± 3°C with a relative humidity of 85 ± 5%. The resistance to hand soldering heat test requires dipping the sensor in solder at 25 ± 10°C, ensuring the solder reaches up to the point far from the body. Lastly, the high temperature operating test is conducted at 125 ± 10°C with the maximum supply voltage (Vcc). Variations in Hall Voltage (Vh) and input/output resistances (Rin/out) are kept below 20%, and the offset voltage (Vo) variation is maintained within ±16mV. Other parameters remain within the specified ranges stated .
These sensors are versatile and can be used in various applications, including the detection of opening and closing mechanisms in mobile phones and PCs, and joystick detection. They are also suitable for use in magnetic encoders and current measurement with overhead wire ammeters (clamp type ammeters). Additionally, they can be employed for position detection in brushless motors, wheel rotation speed detection, and contactless commutation. These sensors are ideal for speed measurement and angular position sensing/indexing in consumer home appliances, office equipment, and industrial applications.
