Direct TPMS systems in product design in the face many difficulties
05/08/2013 12:38
TPMS's life in general to reach 8 to 10 years, which alone a 500mAh battery (battery capacity over the General Assembly to increase the volume and weight transmitter module) transmitter is designed to maintain the work really is not a small problem. In addition to hardware circuit design power...
using different cathode materials
02/08/2013 10:48
using different cathode materials, new lithium-ion batteries have started to develop. When using this type of battery pack, the design engineer should observe electrical specification limits and adjust the drive circuit. Using the maximum forward voltage of the LED is 3.4V ~ 4V when the input...
thickness and shape are very important
