Allegro MicroSystems Inc. Factory Programmed Duel Output Linear A1359LLETR-RP-T

New applications for linear output Hall-effect sensors, such as displacement and angular position, require high accuracy in conjunction with redundant outputs. The Allegro A1359 programmable, linear, Hall effect sensor IC has been designed specifically to achieve both goals. The features associated with this linear device make it ideal for use in automotive and industrial applications requiring high accuracy, and this temperature-stable device operates across an extended temperature range: –40°C to 150°C.

The accuracy of the device is enhanced via programmability at the Allegro factory for optimization of device sensitivity, the quiescent voltage output (QVO: output with no magnetic field), and quiescent duty cycle (QD) for a given application or circuit. The A1359 also allows optimized performance across the entire operating temperature range via programming the temperature coefficients for both sensitivity and QVO/QD at Allegro end-of-line test. This ratiometric Hall effect sensor IC provides a analog voltage, and a PWM signal with duty cycle, that are proportional to the applied magnetic field.

Each BiCMOS monolithic circuit integrates a Hall element, temperature-compensating circuitry to reduce the intrinsic sensitivity drift of the Hall element, a small-signal high-gain amplifier, a clamped low-impedance output stage and a proprietary dynamic offset cancellation technique.

The A1359 is provided in an 8-contact surface mount TSSOP (suffix LE) which is lead (Pb) free, with 100% matte tin leadframe plating.
