ACS711KEXLT-31AB-T
The ACS711KEXLT-31AB-T, manufactured by Allegro MicroSystems, is a Hall effect sensor designed for AC/DC current measurement applications. It runs on a single channel and has a 31A capacity. It has a rapid response time of 4.6 microseconds and a linearity of ±1% with a supply voltage range of 3V to 5.5V.
Description
Overview
- The ACS711KEXLT-31AB-T is a current sensor that boasts a broad bandwidth of 100 kHz, a low-noise analog signal route, and overcurrent fault trips at 100% of full-scale current. It runs on a single supply voltage of 3 to 5.5 V, is available in compact, and has an incorporated electrostatic shield for stability. A steady output offset voltage and no magnetic hysteresis are guaranteed by the precise factory trimming of every unit. Its output is ratiometric with respect to the supply voltage, which offers calibration and integration flexibility.
 
Packaging and Variants
-  
The package for this product, labeled as the 12-contact QFN (12-QFN) in the 3x3 mm size with a thickness of 0.75 mm, is known as the 12-PowerWFQFN. Because of its small footprint design, this package is appropriate for applications with restricted space. With its low profile of 0.75 mm and dimensions of 3 mm by 3 mm, it provides an area-saving option for electrical designs. The gadget can effectively interface with external circuitry thanks to its 12-contact layout. 
- There are several product models in this series to select from, each with a few minor variances in its specifications. As a result, it's critical to compare them while choosing to identify the best model.
