A power control device that protects against MOSFET burnout was designed using a well-known gated-oscillator circuit. The circuit prevents excessive On time for the MOSFETs beyond a permitted limit.

While DSPs are the primary controllers in uninterruptible power supplies (UPS) with power-factor correction (PFC), ac generation and battery management, microcontrollers serve secondary functions for ...

With any low-power design, the designer has the choice between choosing low-power components or switching off the power to peripheral devices. When considering the choice of non-volatile flash ...

Advancing GSM architectures many not seem like a sexy topic in an age where 2.5G and 3G technologies are the talk of the town. However, the reality is that like AMPS in the past GSM is becoming a base ...

A new type of device provides designers of automated installations for North America with performance, cost, and safety benefits. Industrial machinery and equipment system designs typically rely on ...

An ordinary automatic room power control circuit has only one light sensor. So when a person enters the room it gets one pulse and the lights come ‘on.’ When the person goes out it gets another pulse ...
