Allegro introduces a high detail, programmable two-wire Hall-effect linear sensing unit with a pulse breadth modulated (PWM) output. This is the first linear Hall-effect sensor via Allegro to include a current regulator, which allows the device being powered directly from a battery. The duty cycle in the PWM output signal will be proportional to an applied magnetic field. Allegro’s A1354 gadget converts an analogue signal from its internal Hall sensor factor to a digitally protected PWM output signal. The particular coupled noise defense of the digitally protected PWM output is far better than the noise health of an analog output signal. This brand new device is targeted at both the automotive and industrial sectors.

The BiCMOS, monolithic signal inside of the A1354 integrates a Hall element, accuracy temperature-compensating circuitry to reduce the actual intrinsic sensitivity and also offset drift with the Hall element, any small-signal high-gain amplifier, proprietary vibrant offset cancellation circuits, and PWM conversion circuitry. The dynamic balanced out cancellation circuits reduce the residual offset existing of the Hall element. Hall element balance out is normally caused by gadget over molding, heat dependencies, and thermal anxiety. The high frequency offset cancellation (chopping) time allows for a greater sampling rate, which boosts the accuracy of the output signal and results in quicker signal processing potential.

The A1354 sensor is given in a lead (Pb) no cost 4-pin single inline package (KT suffix), together with 100% matte tin leadframe plating. It is priced at $1.43 in amount of 1,000 and contains a 12-14 week normal lead-time to market.
