PCA9665PW,112 Overview
There is a copy of it in the 20-TSSOP (0.173, 4.40mm Width) package. It is easy to carry thanks to its Tube-shaped packaging. A temperature of -40°C~85°C should be maintained for reliable operation. The 2.3V~3.6VV power source is all you need to use it. The terminations in it can be broken down into 20's. Providing a voltage of 2.5V leads to high efficiency. There are two PCA9665s in the number. The device runs at a frequency of 28.5MHz, which is determined by its clock. It is currently possible to obtain 100μA. There is a 2.5/3.3V setting set on the power supply for the component.
