STMicroelectronics TSC1641
TSC1641 - 60V, 16-bit, High precision, I3C/I2C, digital current/voltage/power/temperature Monitor
The TSC1641 is a high precision current, voltage, power, and temperature monitoring analog front-end (AFE). 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.
The TSC1641 allows the assertion of several alerts on the voltage, current, power, temperature signals and thresholds can be set for each parameter in a specific register.
The TSC1641 comes in a plastic DFN10 package and can operate from -40 °C to 125 °C ambient temperature.

STEVAL-DIGAFEV1 - Evaluation board for the TSC1641, 16-bit, high precision current and power monitor with MIPI I3C/I2C interface
The STEVAL-DIGAFEV1 evaluation board allows the user to evaluate the performance of the TSC1641 16-bit, high precision current and power monitor with MIPI I3C/I2C interface.
The board can measure voltage up to 60V, a load current up to 10A, deliver the power, and the temperature, based on the dual channel power monitor.
The current measurement can be high-side, low-side and bidirectional. Analog filters can be implemented on the board.
Pull ups can be enabled/disabled for I2C/I3C communication. It allows consumption optimization. Address can be selected on the board with jumpers.
The board is supplied in ready-to-use in standalone mode, or it can be connected to a NUCLEO-L476RG or NUCLEO-H503RB board with an STM32 microcontroller, which enables further signal processing and PC communication. This product can be used with the STSW-DIGAFEV1GUI (only compatible with STM32H503RB).
