FSD7608-C in the application of large current range, because the current flows through the original side path will produce a certain amount of heat, the use of appropriate Layout, such as increasing the thickness of copper, area and the number of PCB layers, can have a better heat dissipation effect. FSD7608-C chip bottom PCB slot, can increase the creepage distance.
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.
