STMicroelectronics Rolls Out Feature-Rich Digital Power Monitor for Streamlined Energy Management
In a bid to advance energy management technologies, STMicroelectronics has released the TSC1641, a state-of-the-art digital power monitor with the capability to precisely measure current, voltage, and power. Equipped with high-precision input channels, this innovative device also supports the sophisticated MIPI I3C1 bus interface for seamless integration.
Aimed at enhancing efficiency and dependability, the TSC1641 is a key player in a variety of high-demand applications. Its offerings are crucial for improving operations in industrial-grade battery packs, converters, and power supplies, as well as infrastructural hardware such as data center and telecommunications equipment, not to mention its versatility in hand-held power tools.
Key to its design is the dual-channel 16-bit ADC, which ensures concurrent monitoring of DC current and voltage. By doing so, it allows for the internal computation of power that, when synchronized, affords an exceptional level of precision in power usage evaluations.
Connectivity with host systems is made versatile with I2C, SMBus, and MIPI I3C communications, enhancing device reporting. The TSC1641 doesn't just report metrics—it actively safeguards the system by signalling abnormal conditions that could lead to circuit damage, thanks to its comprehensive warning system complete with a dedicated alert pin and onboard temperature sensor.
The TSC1641 demonstrates its adaptability with an extensive operational voltage range that extends up to 60V, making it appropriate for diverse industrial environments. Together with the capability to connect to an external shunt resistor, the monitor is able to accommodate high-side, low-side, and even bi-directional current measurements, all while maintaining minimal system power consumption, evident in its ultra-low 50nA shutdown mode draw.
The integration capacity is further exemplified by the MIPI I3C interface, through which the TSC1641 can connect directly with modern microcontrollers such as the STM32H5 series from ST, enabling advanced system management. Additionally, its high-speed, 12.5MHz data-rate support adds value while its no-need for pull-up resistors offers material savings and conserves space on printed circuit boards.
The TSC1641 is tailored for operation across an expansive temperature range—from -40°C to 125°C—and is ready for production. With prices beginning at an accessible $1.83 per unit for bulk orders of 1000 pieces, housed in a compact 3.0 mm x 3.0 mm plastic DFN10 package, the TSC1641 stands as a testament to STMicroelectronics' commitment to precision instrumentation and energy-efficient designs, ready to serve the ever-growing needs of energy management systems.
