The VCP Monitor Click is add-on board power monitor system. This Click board™ is based on INA260AIPWR - precision digital current and power monitor with low-drift, integrated precision shunt resistor, from Texas Instruments. Therefore, using VCP Monitor Click, current, voltage and power can be monitored. The integrated current-sensing resistor ensures measurement stability over temperature as well as simplifying printed-circuit board layout difficulties common in high precision current sensing measurements.
VCP Monitor Click is supported by a mikroSDK compliant library, which includes functions that simplify software development.
The VCP Monitor Click is power monitor system, which includes precision measurement of current, voltage and power with low-drift. The main IC on the VCP Monitor Click is INA260AIPWR. The current-sensing resistor is designed as a 4 wire connected resistor that enables accurate measurements through a force-sense connection. The INA260AIPWR is internally calibrated to ensure that the current-sensing resistor and current-sensing amplifier are both precisely matched to one another.
The INA260AIPWR device performs two measurements on power supply bus. The current measurement on LOAD connector, is internally calculated by measuring the voltage developed across a known internal shunt resistor. The features is a physical shunt resistance that is able to withstand current levels higher than the continuous handling limit of 15 A without sustaining damage to the current-sensing resistor or the current-sensing amplifier if the excursions are very brief. The voltage measurement on SUPPLY connector witch is calculated by measuring the voltage from the external VBUS pin to ground. The voltage monitored range from 0V to 36V

The VCP Monitor Click is compatibility with I2C communication protocol. The INA260AIPWR has two peripheral address selection pins, A0 and A1. For I2C peripheral address selection, VCP Monitor Click has two cross-shape jumpers, first for set pin A0 and second for set A1 pin. One cross-shape jumper has four position for select address pin which can be selected with a SMD 0 ohm resistor, address pin can be connected to GND, VS, SCL or SDA pins. The VCP Monitor Click with the two separate jumper on Click board™ user can to set the desired address. The INA260AIPWR provides the opportunity of the 16 possible different I2C addresses.

The INA260AIPWR is supported with ALERT pin, which is connected to the INT pin on mikroBUS™, in order to interrupt the ongoing MCU routine in case of the alert condition. INT pin can be programmed to respond to a user-defined event or to a conversion ready notification.
The voltage level of the logic section can be selected via VCC SEL jumper, between 3.3V and 5V. This allows for both 3.3V and 5V capable MCUs to use the I2C communication lines properly.
