Temperature Sensor IC Provides PWM Output Signal
S-5855A Temperature Sensor with PWM Output Facilitates Overheat Protection and Control.

The S-5855A Series is a very new and unique 1-wire PWM output temperature sensor IC from Seiko Instruments. Developed in CMOS technology low current consumption of only 50microA is one of its merits. It changes the duty cycle of a frequency,Because dimmable lights and dimmer fluorescent bulbs switches are so popular amongst American consumers, this drawback has been a significant one. preset with a single capacitor, according to ambient temperature. The available temperature sensitivities which have to be determined at the time of order are -1%/degree(s)C, -2%/degree(s)C, -3%/degree(s)C and -4%/degree(s)C.Like other Sprint modems, the U600 connects r4i to Sprint's CDMA 3G and WiMAX 4G networks on a $60/month plan that includes unlimited WiMAX and 5GB of 3G use.The starting temperature at which the S-5855A temperature sensor will start to modulate its output signal is also determined at the time of order. It may be selected from +40degree(s)C up to +80degree(s)C in 10degree(s)C increments.sale of LED for lighting applications.  Semileds is led lights only a minor palyer and should currently not be mentioned in the same breath as the other others The duty cycle decreases from 100% when the starting temperature is exceeded by the predetermined percentage per degree C and this decrease is linear against the temperature rise.LED grow light suppliers in China are sky lanterns rolling out models with better price-performance ratios. The primary application for this integrated circuit series is the over-temperature protection of LED lighting as it finds use in flat TV sets and computer LCD monitors. A wide range of applications can be found wherever equipment needs protection against overheating and the heating power can be reduced by reduction of the duty cycle of energy supply. This also is a generally possible range of applications where LEDs are used to make up for lamps or any other lighting purpose.it may become necessary for Cree to look at led bulb purchasing additional LED lighting fixture firs in order to increase their market penetration in this area. CMOS and N-ch open drain are available as output form. The small packages SNT-4A and SOT-23-5 it comes in enable high-density mounting
