T850H-6G - STMicroelectronics

T850H-6G Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal thermal performance?
  STMicroelectronics provides a recommended PCB layout in their application note AN5046, which includes guidelines for thermal pad connection, copper pouring, and via placement to ensure optimal thermal performance.
• How do I handle the thermal shutdown feature during startup?
  The thermal shutdown feature is enabled by default. To handle it during startup, ensure that the device is properly cooled, and the thermal shutdown threshold is not exceeded. You can also consider adding a soft-start circuit to limit the inrush current and reduce the thermal stress during startup.
• What is the recommended input capacitor type and value for the T850H-6G?
  STMicroelectronics recommends using a low-ESR ceramic capacitor with a value of 10uF to 22uF, depending on the specific application requirements. The capacitor should be placed as close as possible to the VIN pin to minimize noise and ensure stable operation.
• How do I ensure electromagnetic compatibility (EMC) compliance with the T850H-6G?
  To ensure EMC compliance, follow the guidelines in STMicroelectronics' application note AN2863, which provides recommendations for PCB layout, component selection, and shielding. Additionally, consider using a common-mode choke and a filter capacitor to reduce electromagnetic interference (EMI).
• What is the maximum allowed voltage on the enable pin (EN) during startup?
  The maximum allowed voltage on the enable pin (EN) during startup is 6V. Exceeding this voltage may damage the device. Ensure that the EN pin is properly biased and protected during startup to prevent voltage overshoots.
