60V IC Battery Monitor Measures State of Charge Parameters with 1% Accuracy
60V IC Battery Monitor Measures State of Charge Parameters with 1% Accuracy
08.02.2017 · News
Linear Technology Corporation introduces the LTC2944 multicell battery monitor, which makes direct measurements of 3.6 V to 60 V battery stacks. Absolutely no level shifting circuitry on the supply and measurement pins is required to interface with multicell voltages, so total current consumption is minimized and measurement accuracy is preserved. The LTC2944 is a true high voltage battery monitor that measures charge, voltage, current and temperature to 1% accuracy...

The DA9210-A is a multiphase, automotive grade, 12 A DC-DC buck converter that supplies the high current core rails of microprocessor devices, including those used in next generation infotainment systems taking center stage in today’s connected cars...
Transistor linearly digitizes airflow
Transistor linearly digitizes airflow
02.02.2017 · Circuits
A sensitive and reliable way to measure airflow is to take advantage of the predictable relationship between heat dissipation and air speed. The principle of thermal anemometry relies on King's Law, which dictates that the power required to maintain a fixed differential between the surface of a heated sensor and the ambient air temperature increases as the square root of air speed...
