  • Humanizing the Interface: Voice Activated Devices
    The opto - isolator has high direct current transfer ratio and its output is given to the driver.
  • Digital and Analogue Instrumentation: testing and measurement
    The TMP 03 (Figure 14.12(a)) has an open collector NPN output suitable for driving a high current load, such as an opto - isolator .
  • Physics of Semiconductor Devices
    This device is particularly useful in opto - isolator applications because it offers a high current -transfer ratio, i.e., the ratio of output photodetector current to the input light-source (LED or laser) current, of the order of 50% or more, as …
  • Building a Home Security System with BeagleBone
    External opto - isolator Wiring of such high voltage and high current loads should probably .
  • The development and deployment of an ultrasonic under-sodium viewing system in the fast breeder test reactor
    The driver circuit (see Fig. 6) supply the necessary high current required for driving the motor coils and also use opto - isolators to protect the com- puter from the high-voltage spikes induced during the coil switching.
  • CR4 - Thread: Tmote for PWM
    If your Tmote output is not sufficient, you can use a gate driver chip, a pullup resistor, a high output digital buffer, opto - isolator , opamp or another transistor to get the current /voltage that you need, again depending on how much current …
  • Instrumentation for NMR spin-warp imaging
    The recharging current switch is based on a high voltage power transistor (BUY69B) controlled via an opto - isolator (CNY17); the key to this part of the circuit is the provision of a floating low-voltage DC supply with an isolation of at …
  • Magnetic Sensors Market Tracker - H2 2013
    The simplest current sensors are shunt resistors (including an opto - isolator ), current sensing transformer, Hall Efect IC and inally at the very high performance end, open and closed loop Hall devices and luxgate transducers, which ofer better accuracy and linearity than the …
  • Magnetic Sensors Market Tracker - H1 2013
    The simplest current sensors are shunt resistors (including an opto - isolator ), current sensing transformer, Hall Efect IC and inally at the very high performance end, open and closed loop Hall devices and luxgate transducers, which ofer better accuracy and linearity than the …
  • Magnetic Sensors H1 2012 Market Tracker
    The simplest current sensors are shunt resistors (including an opto - isolator ), current sensing trans- formers, Hall Effect ICs, and inally at the very high -performance end, open and closed-loop Hall devices and luxgate transducers, which offer better accuracy and linearity than …
