High Precision, Programmable Linear Hall Effect Sensor IC with EEPROM, SENT and PWM Output Protocols, and Advanced Output Linearization

Advanced 32-segment output linearization functionality enables high output accuracy and linearity in the presence of non-linear input magnetic fields

Selectable digital SENT (Single Edge Nibble Transmission) or PWM (Pulse Width Modulation) output

SENT output is SAEJ2716 JAN2010 compliant with Allegro Proprietary Enhanced Programmable Features

Customer programmable sensitivity offset, bandwidth, output polarity, output clamps, 1st and 2nd order temperature compensation

Simultaneous programming of all parameters for accurate and efficient system optimization

Factory trimmed magnetic input range (coarse sensitivity) and signal offset

Sensitivity temperature coefficient and magnetic offset drift preset at Allegro, for maximum device accuracy without requiring customer temperature testing

Temperature-stable, mechanical stress immune, and extremely low noise device output via proprietary four-phase chopper stabilization and differential circuit design techniques

Diagnostics for open circuit, overvoltage, and undervoltage

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