Current 12 Click

How does it work?

Current 12 Click is based on the TSC1641, a 60V 16-bit high-precision power monitor with an I2C interface from STMicroelectronics. The TSC1641 is a high-precision analog front-end (AFE) that monitors current, voltage, power, and temperature. It measures current through a shunt resistor and load voltage from 0V up to 60V in a synchronized manner. The current measurement can be high-side, low-side, and bidirectional. The device integrates a high-precision 16-bit resolution dual-channel sigma-delta ADC with a programmable conversion time ranging from 128µs to 32.7ms. This board makes it ideal for applications such as industrial battery packs, power inverters, DC power supplies, data centers, telecom equipment, power tools, and more.

Current 12 Click uses a standard 2-wire I2C communication protocol to enable the host MCU to control the TSC1641. The I2C interface supports clock frequencies of up to 1MHz, with the I2C address selectable via the ADDR SEL jumpers. The alert interrupt ALR pin allows the assertion of several alerts regarding voltage, current, power, and temperature, with thresholds that can be set for each parameter in a specific register.

This Click board™ can be operated only with a 3.3V logic voltage level. The board must perform appropriate logic voltage level conversion before using MCUs with different logic levels. Also, it comes equipped with a library containing functions and an example code that can be used as a reference for further development.

Software Support

We provide a library for the Current 12 Click as well as a demo application (example), developed using MIKROE compilers. The demo can run on all the main MIKROE development boards.

Package can be downloaded/installed directly from NECTO Studio Package Manager(recommended), downloaded from our LibStock™ or found on MIKROE github account.

Library Description

This library contains API for Current 12 Click driver.

Key functions

• current12_get_load_voltage This function reads the load voltage measurement values [V].

• current12_get_dc_power This function reads the DC power measurement values [W].

• current12_get_current This function reads the current measurement values [mA].

Example Description

This example demonstrates the use of the Current 12 Click board™ by reading and displaying the input current measurements.

void application_task ( void )  
 { 
     float meas_data = 0; 
     if ( CURRENT12_OK == current12_get_shunt_voltage( &current12, &meas_data ) ) 
     { 
         log_printf( &logger, " Shunt Voltage: %.2f [mV]rn ", meas_data ); 
         Delay_ms( 100 ); 
     } 

     if ( CURRENT12_OK == current12_get_load_voltage( &current12, &meas_data ) ) 
     { 
         log_printf( &logger, " Load Voltage: %.2f [V]rn ", meas_data ); 
         Delay_ms( 100 ); 
     } 

     if ( CURRENT12_OK == current12_get_dc_power( &current12, &meas_data ) ) 
     { 
         log_printf( &logger, " DC Power: %.2f [W]rn ", meas_data ); 
         Delay_ms( 100 ); 
     } 

     if ( CURRENT12_OK == current12_get_current( &current12, &meas_data ) ) 
     { 
         log_printf( &logger, " Current: %.2f [mA]rn", meas_data ); 
         Delay_ms( 100 ); 
     } 
     log_printf( &logger, "_____________________rn " ); 
     Delay_ms( 2000 ); 
 }

The full application code, and ready to use projects can be installed directly from NECTO Studio Package Manager(recommended), downloaded from our LibStock™ or found on MIKROE github account.

Other MIKROE Libraries used in the example:

• MikroSDK.Board
• MikroSDK.Log
• Click.Current12

Additional notes and informations

Depending on the development board you are using, you may need USB UART click, USB UART 2 Click or RS232 Click to connect to your PC, for development systems with no UART to USB interface available on the board. UART terminal is available in all MIKROE compilers.

mikroSDK

This Click board™ is supported with mikroSDK – MIKROE Software Development Kit. To ensure proper operation of mikroSDK compliant Click board™ demo applications, mikroSDK should be downloaded from the LibStock and installed for the compiler you are using.
