ISL9301IRZ - Renesas Electronics

Description: The ISL9301 is a fully integrated high input voltage single-cell Li-ion battery charger with power path management function. This charger performs the CC/CV charge function required by Li-ion batteries. The charger accepts an input voltage up to 28V but is disabled when the input voltage exceeds 10.5V OVP threshold. The 28V rating eliminates the overvoltage protection circuit required in a low-voltage charger. The charge current and the end-of-charge (EOC) current are programmable with external resistors. W

ISL9301IRZ Frequently Asked Questions (FAQs)

  • A 4-layer PCB with a solid ground plane and a separate power plane is recommended. Keep the input and output capacitors close to the IC, and use short, wide traces for the power lines. Avoid routing sensitive signals near the switching node.
  • Monitor the IC's junction temperature (TJ) and ensure it stays below the maximum rating of 125°C. Calculate the power dissipation (PD) and ensure it's within the SOA. Use thermal design and simulation tools to optimize the PCB layout and thermal management.
  • Choose capacitors with low ESR, high ripple current rating, and a voltage rating that exceeds the maximum input voltage. Ensure the capacitors are placed close to the IC and connected with short, wide traces. X5R or X7R ceramic capacitors are recommended.
  • Use the datasheet's recommended compensation network values as a starting point. Adjust the values based on the specific application's requirements and PCB layout. Use simulation tools to optimize the compensation network for stability and transient response.
  • Use a shielded enclosure, and ensure the PCB layout minimizes radiated emissions. Use a common-mode choke and Y-capacitors to filter the input and output lines. Follow good EMC design practices, such as keeping sensitive signals away from the switching node.
