TS4890IDT Frequently Asked Questions (FAQs)

  • STMicroelectronics provides a recommended PCB layout in the application note AN4571, 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 pin, which goes low when the device reaches the thermal shutdown temperature (typically 150°C). When TSD is low, the device is in shutdown mode. Wait for the device to cool down before re-enabling it.
  • Although the datasheet specifies a maximum input voltage of 5.5V, it's recommended to limit the input voltage to 5V to ensure reliable operation and prevent damage to the device.
  • Follow the guidelines in the application note AN2679, which provides recommendations for PCB layout, component selection, and shielding to ensure EMC compliance with the TS4890IDT.
  • A 10uF to 22uF X7R or X5R ceramic capacitor is recommended for the input pin. This value provides a good balance between noise filtering and stability. Make sure to choose a capacitor with a suitable voltage rating and temperature coefficient.
