Hall Current 15 Click Board™

Product Code: MIKROE-5175

How Does The Hall Current 15 Click Board™ Work? The Hall Current 15 Click Board™ as its foundation uses the TMCS1101-Q1, a precise Hall-effect current sensor featuring a 600V isolation working voltage, <1.5% full-scale error across temperature, and device options providing both unidirectional and bidirectional current sensing from Texas Instruments. The input current flows through an internal 1.8mΩ conductor that generates a magnetic field measured by an integrated Hall-effect sensor and amplified by a precision signal chain. The device has a bandwidth of 80kHz and can be used for AC and DC current measurements. It is optimized for high accuracy and temperature stability, with offset and sensitivity compensated across the operating temperature range. The Hall Current 15 Click Board™ possesses two ways to communicate with the MCU. The analogue output signal of the TMCS1101-Q1 can be converted to a digital value using ADC101C021, a 10-bit resolution analogue-to-digital converter from Texas Instruments using a 2-wire I2C compatible interface, or can be sent directly to an analogue pin of the mikroBUS™ socket labelled as AN.

Selection can be performed by onboard SMD switch labelled as OUT SEL, setting it to an appropriate position marked as AN or ADC. The ADC101C021 can transfer data supporting modes up to High-Speed, alongside its alert function, which provides an interrupt routed to the ALR pin of the mikroBUS™ socket activated when analogue input violates a programmable upper or lower limit value. Also, this Click board™ should be connected in series with the load. The current is measured by two onboard terminal connectors, one terminal block for the positive and the other for the negative current input. The Hall Current 15 Click Board™ 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 board™ comes equipped with a library containing easy-to-use functions and an example code that can be used, as a reference, for further development.
