STMicroelectronics provides a recommended PCB layout for the TSH690IDT in the application note AN5323, which includes guidelines for thermal vias, copper pours, and component placement to ensure optimal thermal performance.
To ensure reliable operation at high temperatures, it's essential to follow the recommended operating conditions, including the maximum junction temperature (Tj) of 150°C. Additionally, consider using thermal management techniques such as heat sinks, thermal interfaces, and airflow to keep the device temperature within the recommended range.
The maximum allowed voltage on the input pins of the TSH690IDT is the supply voltage (VCC) + 0.5V. Exceeding this voltage can cause damage to the device. It's essential to ensure that the input voltage does not exceed this limit to prevent damage or malfunction.
The TSH690IDT has built-in ESD protection, but it's still essential to follow proper ESD handling procedures during assembly and testing. This includes using ESD-safe materials, grounding straps, and ionizers to prevent static electricity from damaging the device.
The recommended power-up sequence for the TSH690IDT is to apply the supply voltage (VCC) before applying the input signals. This ensures that the device is properly initialized and configured before receiving input signals.
