This board features the TMCS1108A2U, a galvanically isolated Hall-effect current sensor with high accuracy, excellent linearity, and temperature stability from Texas Instruments. The input current flows through an internal 1.8m�© conductor that generates a magnetic field measured by an integrated Hall-effect sensor. It features a 100V functional isolation working voltage with both unidirectional and bidirectional current sensing. Based on the selected logic voltage VCC, the TMCS1108A2U allows the user to measure current in two appropriate ranges, where after that, can process the output signal in analog or digital form. This Click boardâ�¢ is suitable for AC or DC current-sensing in industrial, commercial, and communications systems.\u003c\/p\u003e \u003cp\u003eHall Current 11 Click is supported by a mikroSDK compliant library, which includes functions that simplify software development.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eDO NOT TOUCH THE BOARD WHILE THE EXTERNAL POWER SUPPLY IS ON!\u003c\/strong\u003e\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eNote:\u003c\/strong\u003e This Click boardâ�¢ needs to be used by trained personnel only while applying high voltages. Special care should be taken when working with hazardous voltage levels.\u003c\/p\u003e \u003cp\u003eHall Current 11 Click as its foundation uses the TMCS1108A2U, a precision Hall-effect current sensor, featuring a 100V functional isolation working voltage, \u0026lt;3% full-scale error across temperature, and both unidirectional and bidirectional current sensing from Texas Instruments. The input current flows through a 1.8m�© resistance conductor between the isolated input current pins, minimizing power loss and thermal dissipation. The magnetic field generated by the input current is sensed by a Hall sensor and amplified by a precision integrated signal chain. The TMCS1108A2U can be used for both AC and DC current measurements with a bandwidth of 80kHz.\u003c\/p\u003e \u003cp\u003eThe TMCS1108A2U is optimized for high accuracy and temperature stability, with both offset and sensitivity compensated across the entire operating temperature range. Based on the selected logic voltage VCC, the TMCS1108A2U allows the user to measure current in two appropriate ranges, where after that, can process the output signal in analog or digital form. With the selected logic voltage of 3.3V, it is possible to measure the current from -2.8A to 27.7A, while with the chosen 5V, it is possible to measure it in the range from -4.5A to 43A.\u003c\/p\u003e \u003cp\u003eThe analog output signal of the TMCS1108A2U can be converted to a digital value using MCP3221, a successive approximation A\/D converter with a 12-bit resolution from Microchip using a 2-wire I2C compatible interface, or can be sent directly to an analog pin of the mikroBUSâ�¢ socket labeled as AN. Selection can be performed by onboard SMD jumper labeled as ADC SEL to an appropriate position marked as AN and I2C.\u003c\/p\u003e \u003cp\u003eThe MCP3221 provides one single-ended input with low power consumption, a low maximum conversion current, and a Standby current of 250�¼A and 1�¼A, respectively. Data can be transferred at rates of up to 100kbit\/s in the Standard and 400kbit\/s in the Fast Mode. Also, maximum sample rates of 22.3kSPS with the MCP3221 are possible in a Continuous-Conversion Mode with a clock rate of 400kHz.\u003c\/p\u003e \u003cp\u003eThis Click boardâ�¢ can operate with both 3.3V and 5V logic voltage levels selected via the VCC SEL jumper. This way, it is allowed for both 3.3V and 5V capable MCUs to use the communication lines properly. However, the Click boardâ�¢ comes equipped with a library containing easy-to-use functions and an example code that can be used, as a reference, for further development.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003c\/p\u003e \u003cul\u003e \u003cli\u003eInterface: Analog, I\u003csup\u003e2\u003c\/sup\u003eC\u003c\/li\u003e \u003cli\u003eCompatibility: mikroBUSâ�¢\u003c\/li\u003e \u003cli\u003eDimensions: 57.15 x 25.4mm\u003c\/li\u003e \u003cli\u003eInput Voltage: 3.3V or 5V\u003c\/li\u003e \u003cli\u003eMeasurement Range @ VCC=3.3V: Min. -2.8A, Max. 27.7A\u003c\/li\u003e \u003cli\u003eMeasurement Range @ VCC=5V: Min. -4.5A, Max. 43A\u003c\/li\u003e \u003cli\u003eSensitivity: 100 mV\/A\u003c\/li\u003e \u003cli\u003eOperating Temperature Range: Min. -40�°C, Typ. +25�°C, +125�°C\u003c\/li\u003e \u003c\/ul\u003e \u003cp\u003e\u003cstrong\u003eDocuments:\u003c\/strong\u003e\u003c\/p\u003e \u003cul\u003e \u003cli\u003e\u003ca href=\"https:\/\/cdn.sparkfun.com\/assets\/0\/b\/3\/7\/7\/Schematic-19154-Hall_Current_11_Click.PDF\"\u003eSchematic\u003c\/a\u003e\u003c\/li\u003e \u003cli\u003e\u003ca href=\"https:\/\/cdn.sparkfun.com\/assets\/3\/1\/b\/d\/3\/MCP3221_datasheet.pdf\"\u003eMCP3221 Datasheet\u003c\/a\u003e\u003c\/li\u003e \u003cli\u003e\u003ca href=\"https:\/\/cdn.sparkfun.com\/assets\/5\/7\/6\/1\/4\/TMCS1108_datasheet.pdf\"\u003eTMC1108 Datasheet\u003c\/a\u003e\u003c\/li\u003e \u003cli\u003e\u003ca href=\"https:\/\/www.mikroe.com\/mikrosdk\"\u003emikroSDK\u003c\/a\u003e\u003c\/li\u003e \u003cli\u003e\u003ca href=\"https:\/\/github.com\/MikroElektronika\/mikrosdk_click_v2\/tree\/master\/clicks\/hallcurrent11\"\u003eGitHub\u003c\/a\u003e\u003c\/li\u003e \u003c\/ul\u003e \u003cp\u003e\u003cstrong\u003eVideos\u003c\/strong\u003e\u003c\/p\u003e \u003cdiv class=\"flex-video-wrap clearfix\"\u003e \u003cdiv class=\"flex-video widescreen img\"\u003e \u003ciframe src=\"https:\/\/www.youtube.com\/embed\/zzlh1oGii1Q\/?autohide=1\u0026amp;border=0\u0026amp;wmode=opaque\u0026amp;enablejsapi=1\" frameborder=\"0\" allowfullscreen width=\"560\" height=\"315\"\u003e\u003c\/iframe\u003e \u003c\/div\u003e \u003c\/div\u003e","brand":"sparkfun-10","offers":[{"title":"Default Title","offer_id":40054695657557,"sku":"19154:SEN-19154:spark","price":4980.0,"currency_code":"INR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1034\/1611\/products\/19154_-_Hall_Current_11_Click_2.jpg?v=1651343303","url":"https:\/\/www.tanotis.com\/products\/sparkfun-mikroe-hall-current-11-click","provider":"Tanotis","version":"1.0","type":"link"}
