TS4871IST datasheet by STMicroelectronics

TS4871IST 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 solid ground plane and a thermal relief pattern under the IC to ensure optimal thermal performance.
• How do I ensure the TS4871IST is properly powered up and configured?
  The TS4871IST requires a single 1.8V power supply, and the EN pin should be tied to VCC to enable the device. Additionally, the RST pin should be pulled up to VCC through a resistor to ensure proper reset.
• What is the maximum capacitive load that can be driven by the TS4871IST?
  The TS4871IST can drive up to 400pF of capacitive load on its outputs, but it's recommended to limit the load to 200pF for optimal performance.
• How do I troubleshoot issues with the TS4871IST?
  STMicroelectronics recommends using a logic analyzer or oscilloscope to monitor the device's inputs and outputs, and checking the power supply and PCB layout for any issues.
• Are there any specific ESD protection measures I should take when handling the TS4871IST?
  Yes, the TS4871IST is a sensitive device and requires proper ESD protection during handling and assembly. It's recommended to use an ESD wrist strap, mat, or workstation to prevent damage.
