... AMB D JA When a CM3109-00SB/SH (PSOP) is mounted on a double sided printed circuit board with two square inches of copper allocated for "heat spreading", the θ resulting is 40°C/W. Based on the over tempera- JA ture limit of 150°C with an ambient of 85°C, the avail- ...

... If this average current is exceeded, the device will go over-temperature and the output will drop to 0V. The theoretical calculations of these relationships show the safe operating area of the CM3109 in the PSOP package. Thermal characteristics were measured using a double sided board with two square inches of copper area connected to the GND pins for " ...

... It also helps dissipation to spread if the chip is positioned away from the edge of the PCB, and not near other heat dissipating devices. A good thermal link from the PCB pad to the rest of the PCB will ensure a thermal link from the CM3109 package to ambient, θ around 40°C/W. JA ▲ ...
