03.02.2017 · News
Dialog Semiconductor announced the DA9210-A power management IC. 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
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...

Electrolytic Capacitor-Based Data Backup Power Solution for a 12V System Regulated from 5V to 36V Input
31.01.2017 · Circuits
Data loss is a concern in telecom, industrial and automotive applications where embedded systems depend on a consistent supply of power. Sudden power interruptions can corrupt data during read and write operations for hard drives and flash memory. Often, embedded systems need just 10 ms to 50 ms to backup volatile data to prevent loss...
