A1359

Factory-Programmed Dual Output Linear Hall Effect Sensor IC

With Analog and Pulse Width Modulated Outputs

Features and Benefits

Description

• Dual tracking outputs: analog voltage output and pulse

width modulated (PWM) output

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.

• Matched analog and PWM outputs enable user to detect

various output error conditions

• Factory-programmed offset, sensitivity, and polarity

• Sensitivity temperature coefficient (TC) and QVO/QD

temperature coefficient programmed at Allegro^™for

improved accuracy

• High speed chopping scheme minimizes quiescent voltage

output (QVO) drift across temperature

• Temperature-stable QVO and sensitivity

• Output voltage clamps provide short circuit diagnostic

capabilities

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.

• Wide ambient temperature range: –40°C to 150°C

• Immune to mechanical stress

• Enhanced EMC performance for stringent automotive

applications

Package: 8-pin TSSOP (suffix LE)

surface mount

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
