UM3202 User manual Getting started with the STEVAL-DIGAFEV1 evaluation board for the TSC1641 Introduction The STEVAL-DIGAFEV1 allows to evaluate the measurement performance and features of the TSC1641, designed to measure current, voltage and power. The board can accept external voltage and current to measure and evaluate the conversion performance of the TSC1641 conversion performance, based on its Delta-Sigma (ΔΣ) modulators. Thanks to a led on the board, it is easy to monitor if the alert pin is active. The STEVAL-DIGAFEV1 can be supplied in standalone mode. It can also be connected to a NUCLEO-H503RB development board that hosts an STM32 microcontroller, allowing further signal processing and communication with the PC. Figure 1.

It monitors current into a shunt resistor and load voltage up to 60 V in a synchronized way. The current measurement can be high-side, low-side and bidirectional. The device integrates high precision 16-bit dual channel ADC with a programmable conversion time from 128 µs to 32.7 ms. The digital bus interface is flexible from an I²C/SMbus 1 MHz data rate to an MIPI I3C 12.5 MHz data rate. This allows connectivity to most of the recent STM32 products. UM3202 - Rev 1 page 2/18 UM3202 How to use the board 2 How to use the board 2.1 Standalone The STEVAL-DIGAFEV1 can be used directly with your testing device or I2C/I3C controller. Step 1. Connect ground and supply voltage On the CN1 connector, connect your supply voltage according to the board serigraphy. Figure 2. CN1 connector for 3.3V power supply UM3202 - Rev 1 page 3/18 UM3202 Standalone Step 2. Connect the I2C/I3C bus On connector CN2, the two top connections are for SDA (data) and SCL (clock). Connections are clearly labeled in the serigraphy. Figure 3. CN2 connector for I2C/I3C connection I²C I²C communication bus requires pull-up resistors. The STEVAL-DIGAFEV1 has two 4.7k ohm pull-up resistors on SDA and SCL lines. These pull-up resistors can be connected thanks to JP_SDA and JP_SDL jumpers. Figure 4. Jumpers to connect SDA and SCL pull-up resistors It is also needed to give to the TSC1641 a static address by changing the with the A0/A1 value thanks to JP_A0 and JP_A1 jumpers.

The maximum communication speeds are detailed table for I²C & I3C speeds. Table 2. Table for I²C & I3C speeds Communication type Speed I²C 1 MHz I3C 12.5 MHz Step 3. Connect load and Vload power to supply For high-side measurement, connect your power supply (the vload to measure) to the J1 connector, and the load to the J2 connector. Figure 6. J1 and J2 connectors for LOAD connection UM3202 - Rev 1 page 5/18 UM3202 With a NUCLEO-STM32 2.2 With a NUCLEO-STM32 To use the board, follow below procedure: Step 1. Plug the STEVAL-DIGAFEV1 The STEVAL-DIGAFEV1 is compatible with the wide majority of Nucleo board thanks to its Arduino pinout. Connecting the STEVAL-DIGAFEV1 to a nucleo make it supplied by the 3.3V of the nucleo board. For a better interconnection, it is better to use the NUCLEO-H503RB which support I3C communications. Table 3.

It is necessary to program the nucleo-64 H503RB with the STSW-DIGAFEV1FW to use it. The STSW-DIGAFEV1FW runs on an STM32 Nucleo-64 development board NUCLEO-H503RB. It communicates with the TSC1641 of the STEVAL-DIGAFEV1 through the I2C and I3C protocols. The STSW-DIGAFEV1GUI allows the user to write configuration registers, monitor current, voltage, and power and plot data on a graph. It is also a tool to save values measured by the TSC1641 in a .csv file. For more information on the STSW-DIGAFEV1GUI, go to the relevant ST web page. Figure 7. STSW-DIGAFEV1GUI graphical user interface Option B: use the STEVAL-DIGAFEV1 directly with your test solution The STEVAL-DIGAFEV1 can be plugged directly to your solution.

During the radiated immunity testing, the board obtained level B, meaning that the board was not damaged during the test, but showed a performance degradation of over 2% in voltage and current measurement.
