Thermal Shutdown (TSD) Thermal Shutdown Circuit turns OFF all outputs when the junction temperature typically reaches 150°C. It is intended to protect the device from failures due to excessive junction temperature. The Thermal Shutdown has the hysteresis of 40°C approximately. 2. Printed Circuit Board (PCB) Layout If high current flows on the power supply(PVCC) and GND line, it can be misoperated due to the line oscillation. The following points should be kept in mind regarding as the pattern layout to prevent it. • Making the wiring lines thick and short, especially between power supply (PVCC) and GND. • Putting a passthrough capacitor near the IC The Rth-ja of the FAN8100N/MTC can be reduced by soldering the GND pins to a suitable copper area of the printed circuit board as shown in following figure. It is recommended the copper area is as large as possible. Example of PCB copper area which is used as heatsink 8 FAN8100N/FAN8100MTC Typical Application Circuits 1.
