A good thermal design should be used to ensure optimal heat dissipation. A minimum of 2 oz copper thickness is recommended, and thermal vias should be placed under the device to dissipate heat efficiently.
To ensure EMC, use a shielded cable for the output stage, and consider adding a common-mode choke and a ferrite bead to the output lines. Additionally, ensure good PCB layout practices, such as separating analog and digital grounds.
The maximum allowed voltage on the input pins is 7V, exceeding which may cause damage to the device. Ensure that the input voltage is within the recommended operating range to prevent damage.
To troubleshoot issues, start by checking the power supply voltage, input signals, and output loads. Use an oscilloscope to verify the input and output waveforms, and check for any signs of overheating or electrical overstress.
The TLE7274-2D is rated for operation up to 150°C, but the device's performance and reliability may degrade at high temperatures. Ensure that the device is properly cooled, and consider using a heat sink or thermal interface material to improve heat dissipation.
