"When choosing a current-sensing solution, design engineers weigh the trade-offs of four key factors: cost, size, accuracy and speed," said Jason Cole, business unit manager. "These new products highlight how the breadth of our sensing technologies address this design challenge for a variety of systems. Take the TMCS1123, for example; its high accuracy and low propagation delay enable designers to now use Hall-effect sensors in high-voltage systems where they couldn't before – and that opens the door to reduce system cost and size."
Achieve fast, accurate control in high-voltage systems with Hall-effect current sensors
The need for highly accurate current measurements in high-voltage systems such as electric vehicle chargers and solar inverters is growing, but Hall-effect current sensors have typically been overlooked given their high drift over lifetime. The TMCS1123 Hall-effect current sensor features the highest reinforced isolation working voltage of 1,100 VDC. The TMCS1123 also features a maximum sensitivity error of ±
In addition, achieving precise control of power conversion is paramount for optimizing system efficiency and protection. The TMCS1123 features low propagation delay of 600 ns and bandwidth of 250 kHz, which enable faster control loops while keeping noise low to help increase system efficiency.

Simplify and reduce system size with EZShunt technology
TI's new EZShunt portfolio of current-sensing solutions simplifies designs by removing the need for an external shunt resistor. The portfolio provides a fully integrated current-sensing solution that fits within the footprint of a 1206 shunt resistor, offering the value of a discrete solution with the simplicity of a single chip.
The EZShunt portfolio offers both cost-optimized and high-accuracy options, featuring drift as low as 25 ppm/°C, in a variety of packages and shunt values. The INA700 is the industry's smallest integrated current shunt monitor, enabling engineers to reduce the size of their current-sensing solution by as much as
TI's new Hall-effect and EZShunt current-sensing solutions build on the company's commitment to helping engineers sense the world more accurately. To learn more, see TI.com/sensing.
