The ACS75x family is lead-free. The terminals of the conductive path are electrically isolated from the sensor leads pins 1 through 3. Trial and error and possible solution I’ve been trying allot of different approaches to my problem datasgeet wanting to give up and certainly not going to wait for someone to drop code in my lap. This method will not be terribly accurate, because the battery’s useful charge is not exact, and will fluctuate wildly depending on discharge rate and temperature, among other variables, but it should be good enough to provide a rough ‘gas gauge’.

This larger datashret factor, when properly designed for, can offer better measurement resolution. Sign up or log in Sign up using Google. Assuming a more or less pure sinewave, current follows the same pattern, However, for anything other than a pure resistive load, voltage and current will be out of phase and you may or may not have a sinewave.

Allegro Support Just got off the phone with Allegro support who called me back after I emailed them just to confirm I wasn’t going crazy and I didn’t hook up something incorrectly and sure enough the Vout on the ACS will produce a sine wave proportionate datasheft the current being used.


The other two connections are to be placed in series with your load. The example code here should be modified to match your particular sensor. The uni-directional sensors measure current in one direction only and thus allow for a larger scale factor. In a perfect world Still would have the offset voltage, about 2 volts which you subtract out anyway.

I will experiment with that and watch it closely. By continuing to visit this site you agree to accept cookies. With a purely resistive load, you should be able to establish the peak through timing. The only datasheeet to do this accurately is with many nearly simultaneous samples of current and averaging over time.

Date of status change: Dqtasheet device package allows for easy implementation by the customer. In order to measure the current consumption or the battery’s state of charge, you need to integrate current over time. The heavy gauge leadframe is made of oxygen-free copper. Home Questions Tags Users Unanswered. Results 1 to 9 of 9. Samples are no longer available.

It’s not very accurate because of the limited resolution of the converters, and because the important quantity is a small difference between two similar voltages. That is a lot of current to draw from a battery unless it is a Lead-Acid cell cranking a car engine – even then it will only drive this sort of current for a short time.

I came up with this routine that seems to be pretty stable. Print Share on Tumblr.

The device should not be purchased for new design applications. Similar Threads Need a cheap touch sensor idea. The device consists of a precision, low-offset linear Hall sensor circuit with a copper conduction path located near the die. Total current consumed from a battery Ask Question.

I would like to know how could I know the current consumed from a battery using this sensoror other similar, using a microcontroller. Madmanguruman, thank you very much, I don’t knew what was that sensor He also told me the data sheet for the ACS has some peek voltage circuit examples which I am going to look at right now.

He also told me that the have an 8 pin version that for my application will read up to 30 amps and I should really be looking at that. Request Current Sensor Samples. It will also change with non-linear loads which most electronic gear presents.

Don’t worry about the sensor being discontinued, there is a drop-in replacement, the ACS which is pretty much identical but supports a wider voltage range with improved accuracy. So I simplified the heck out of my prorgam and just have it loop through as quickly as possible keeping track of the MAX and displaying that at every count.

Typical applications include motor control, load detection and management, power supplies, and overcurrent fault protection. Each offered range is available as either a uni-directional sensor or a bi-directional sensor. I need to incorporate this into a circuit with another sensor, pressure transducer, hopefully I can run that pressure transducer and 2 of these Allegro ACS’s all on my 16F
