PCB recommended layout

The relationship between junction temperature and primary current of FSD7616-C series chips is measured with the following experimental DEMO board.

PCB DEMO board information
Number of floors	2 floors
Original side path copper-covered single-layer area	910 mm2
Single layer copper coating thickness	4Oz

The temperature rise of the FSD7616-C junction is mainly due to the spontaneous heat of the current flowing through the path of the primary conductor, and the heat is conducted through the plastic sealing body, lead frame, PCB and air. At normal temperature, the relationship between the continuous loading current (RMS) of FSD7616-C and the incremental junction temperature rise is shown in Figure 18. In the environment of natural air flow at normal temperature, the junction temperature of FSD7616-C generally tends to be stable when the continuous current is loaded for about 10min. As shown in Figure 19, when the DC current is continuously loaded for 50A at 25°C, the relationship curve between junction temperature rise and the loading current time is about 100s. Chip junction temperature is close to 100°C.

The relationship curve between the maximum continuous current loading capability (RMS) of FSD7616-C and the operating ambient temperature is shown in Figure 20. When the ambient temperature is 25°C, the maximum continuous current effective value is 56A. At 125 degrees, it's about 30A. If the junction temperature does not exceed 165°C, the surge or pulse current is allowed to exceed the maximum value listed in the diagram. The use of appropriate Layout, such as increasing the thickness, area and PCB layer of copper, can have a better heat dissipation effect.

Instructions

1) Incorrect cables may damage the sensor.

2)The product power supply voltage VCC must meet specifications. If the voltage is too low, the product cannot be accurately output. If the voltage is too high, the product may be damaged.

3) The RC filtering link between product output VOUT and GND can be added according to actual requirements to adjust product output frequency characteristics.

4)Sensors can be customized according to customer requirements, including supply voltage, measurement current range, pin definition, and more.
