Allegro MicroSystems Europe has added a field programmable precision linear Hall-effect current sensor IC with features including a 240 kHz bandwidth, integrated voltage regulator, reverse battery protection, user-selectable ratiometry, and uni- or bi-directional output options. By Graham Prophet
The user can configure the sensitivity and quiescent (zero field) output voltage through programming on the VCC and output pins, to optimise performance in the end application. The quiescent output voltage is user-adjustable, around 50% (bidirectional configuration) or 10% (unidirectional configuration) of the supply voltage, VCC, and the output sensitivity is adjustable within the range of 0.6 to 6.4 mV/G (Gauss).
