STMicroelectronics provides a recommended PCB layout in the application note AN5323, which includes guidelines for thermal vias, copper pours, and component placement to ensure optimal thermal performance.
The TDE1787DP has a built-in overcurrent protection feature, but it's recommended to add an external overcurrent protection circuit to ensure reliable operation. A possible implementation is to use a sense resistor and a comparator to detect overcurrent conditions and trigger a shutdown signal to the device.
Although the datasheet specifies a maximum VCC voltage of 5.5V, it's recommended to limit the voltage to 4.5V during startup to ensure reliable operation and prevent damage to the device.
To ensure EMC compliance, follow the guidelines in the STMicroelectronics application note AN2679, which provides recommendations for PCB layout, component selection, and shielding to minimize electromagnetic interference (EMI).
Although the datasheet specifies an operating temperature range of -40°C to 125°C, it's recommended to operate the device within a range of -20°C to 85°C for optimal performance and reliability.
