A1363LU Overview
Description
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.
Key Features
- 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
- 90 kHz nominal bandwidth achieved via proprietary packaging and chopper stabilization techniques
- Patented circuits suppress IC output spiking during fast current step inputs
- Open circuit detection on ground pin (broken wire)
- Undervoltage lockout for VCC below specification Continued on the next page… Package: 8-pin TSSOP (suffix LU) Not to scale
