Advanced Hall element sensors for rotation and current detection applications

Diodes Incorporated has introduced 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 in various home appliances. They are designed for position encoders and commutation of brushless motors and fans in industrial applications. The development of these devices satisfies the market demand for greater availability of high-sensitivity InSb Hall sensors in the industry-standard 4-pin SOT23-4 and SIP-4 packages.

The AHE300 InSb sensor supports Hall output voltage (VH) classifications C-G, which range from 168mV to 370mV. The AHE10x sensors support classifications C-H and produce VH up to 415mV. The ultra-high sensitivity of these sensors permits them to operate reliably even in the presence of weak magnetic fields across a broad range of applications. Furthermore, these sensors' low offset voltage (5mV to 7mV) attains the level of resolution needed to deliver high-accuracy detection capabilities.

The AHE300 sensor operates in the -40C to +110C temperatures range, is housed in a SIP-4 (Type MA) package and is available in 500-piece quantities.

The AHE10x devices function over a wider temperature range (-40C to +125C), making them sufficiently robust for harsh thermal environments. For application flexibility, they are supplied in SOT23-4 packaging with various height options (A, B, C) and are available in 3,000-piece quantities.
