T835H-8G-TR Frequently Asked Questions (FAQs)

STMicroelectronics provides a recommended PCB layout in their application note AN5046, which includes guidelines for thermal pad connection, thermal vias, and copper pouring to ensure optimal thermal performance.
The thermal shutdown feature is enabled by default. To handle it, monitor the TSD (Thermal Shutdown) pin, which goes low when the junction temperature exceeds 150°C. When TSD is low, the device is in thermal shutdown mode, and the output voltage is disabled. Wait for the device to cool down before re-enabling the output voltage.
The maximum allowed voltage on the enable pin (EN) is 6V. Exceeding this voltage may damage the device. Ensure that the voltage on the EN pin does not exceed 6V, even during startup or shutdown sequences.
Yes, the T835H-8G-TR is qualified for automotive and high-reliability applications. It meets the AEC-Q100 standard for automotive applications and is suitable for use in harsh environments. However, ensure that you follow the recommended operating conditions and design guidelines to guarantee reliable operation.
Use the equations provided in the datasheet to calculate the power dissipation (PD) and junction temperature (TJ). PD = (VIN - VOUT) x IOUT, and TJ = TA + (PD x RθJA), where TA is the ambient temperature, and RθJA is the junction-to-ambient thermal resistance.
