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

 

  •  package_ACS711KEXLT-31AB-TThe 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.

FAQ

 

Q: What is the ACS711KEXLT-31AB-T's principle of operation?

A: The Hall-effect sensing concept, which measures the magnetic field produced by a current passing through a conductor to determine the current magnitude, is how this model works.

Q: How much current can the ACS711KEXLT-31AB-T measure at its maximum?

A: According to its datasheet, it is capable of measuring currents up to its full-scale rating.

Q: How does the ACS711KEXLT-31AB-T react to circumstances involving overcurrent?

A: To protect against overcurrent circumstances, it has overcurrent fault trips that trip and latch at 100% of full-scale current.

Q: What is the ACS711KEXLT-31AB-T's supply voltage range?

A: The only supply voltage needed for this device to function is between 3 and 5.5 volts.

Q: Can high-frequency applications use the ACS711KEXLT-31AB-T?

A: It is appropriate for high-frequency current sensing applications because of its 100 kHz bandwidth.

Q: What is the ACS711KEXLT-31AB-T's sensitivity?

A: The sensitivity of this product is 45 millivolts per ampere (mV/A), meaning that the output voltage rises by 45 millivolts for each ampere of current that flows through the device.

Q: How quickly does the ACS711KEXLT-31AB-T respond?

A: With its 4.6 microsecond response time, it can detect and react to changes in current flow with exceptional speed and accuracy.

Q: What is the ACS711KEXLT-31AB-T's maximum supply current requirement?

A: With a maximum supply current of 5.5 milliamperes (mA), it ensures effective power usage while in operation.
