Digital power monitor with MIPI I3C and I²C interface for transmitting system data to a microcontroller
The TSC1641 transmits critical power system parameters such as current, voltage, power, and temperature to a microcontroller and can alert undesirable operating conditions.
Its flexible digital bus interface, offering 1-MHz I²C/SMbus and 12.5-MHz MIPI I3C data rates, ensure connectivity with even the most recent microcontrollers, such as the STM32H5 series.
With integrated high-resolution ADCs up to 16 bits, the device can be implemented in low- and high-side current topologies, as well as for bidirectional current monitoring.
Packaged in a small 3 x 3 mm footprint (DFN10), the TSC1641 can sense voltages up to 60 V, while consuming ultralow input bias and shutdown currents.
