TS971ILT datasheet by STMicroelectronics

TS971ILT Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal thermal performance?
  STMicroelectronics recommends a 2-layer or 4-layer PCB with a thermal pad connected to a large copper area on the bottom layer to dissipate heat efficiently.
• How do I ensure reliable operation in high-temperature environments?
  Implement thermal management techniques such as heat sinks, thermal interfaces, and airflow to keep the junction temperature below 150°C. Also, ensure proper PCB design and layout to minimize thermal resistance.
• What is the recommended input capacitor value and type for optimal performance?
  A 10uF to 22uF X7R or X5R ceramic capacitor is recommended for input decoupling, placed as close to the TS971ILT as possible to minimize noise and ensure stable operation.
• How do I minimize electromagnetic interference (EMI) in my design?
  Use a shielded enclosure, keep the TS971ILT away from noise sources, and use a common-mode choke or ferrite bead on the input lines to reduce EMI. Also, ensure good PCB layout practices, such as separating analog and digital grounds.
• What is the maximum allowed voltage on the enable pin (EN) for reliable operation?
  The enable pin (EN) should not exceed 6V to ensure reliable operation and prevent damage to the device.
