A1359 Overview
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.
A1359 Key Features
- Dual tracking outputs: analog voltage output and pulsewidth-modulated (PWM) output
- 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
- 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
- Wide ambient temperature range: -40°C to 150°C
- Immune to mechanical stress
- Enhanced EMC performance for stringent automotive
