Allegro ACS722LLCTR-20AB-T

霍尔效应，开环20A1比率，电压

Overview

The ACS722 and ACS723 devices are true +/-5 Amp sensor ICs or uni-directional 10 A sensor ICs for use in lower-power applications that require higher output swings at lower currents. The ACS722 and ACS723 employ an advanced temperature compensation scheme for Qvo and sensitivity that enables improved performance, even at the much higher gain required for these devices. Providing a full-scale +/-5 A sensor with existing Hall technology was not possible until employing this compensation scheme and we think this product will compete well with other market solutions.

Features

Patented integrated digital temperature compensation circuitry allows for near-closed-loop accuracy over the temperature in an open-loop sensor 

Industry-leading noise performance with greatly improved bandwidth through a proprietary amplifier and filter design techniques

Pin-selectable bandwidth: 80 kHz for high bandwidth applications or 20 kHz for low noise performance

0.65 mΩ primary conductor resistance for low power loss and high inrush current withstand capability

Small footprint, low-profile SOIC8 package suitable for space-constrained applications

Applications

Motor control

Load detection and management

Switched-mode power supplies

Overcurrent fault protection
