A1363LKTTN-2-T

The Allegro A1363 programmable linear Hall-effect current sensor IC has been designed to achieve high accuracy and resolution without compromising bandwidth. The goal is achieved through new proprietary linearly interpolated temperature compensation technology that is programmed at the Allegro factory and provides sensitivity and offset that are virtually flat across the full operating temperature range. Temperature compensation is done in the digital domain with integrated EEPROM technology, without sacrificing the analog signal path 120 kHz bandwidth, making this device ideal for HEV inverter, DC-to-DC converter, and electric power steering (EPS) applications.This ratiometric Hall-effect sensor IC provides a voltage output that is proportional to the applied magnetic field.The quiescent output voltage is user-adjustable around 50% of the supply voltage, VCC, and the output sensitivity is adjustable within the range of 0.6 to 14 mV/G.

• Proprietary segmented linear interpolated temperature compensation (TC) technology provides a typical accuracy of 1% across the full operating temperature range
• Customer programmable, high resolution offset and sensitivity trim
• Factory programmed sensitivity and quiescent output voltage TC with extremely stable temperature performance
• High sensitivity Hall element for maximum accuracy
• Extremely low noise and high resolution achieved via proprietary Hall element and low noise amplifier circuits
• 120 kHz nominal bandwidth achieved via proprietary packaging and chopper stabilization techniques
• Patented circuits suppress IC output spiking during fast current step inputs
