MCP73838T-FCI/MF Frequently Asked Questions (FAQs)

  • The maximum charging current that can be set using the ISET pin is 1.5A. However, the actual charging current may be limited by the internal resistance of the battery and the voltage drop across the internal FET.
  • The MCP73838T-FCI/MF has an internal over-voltage protection (OVP) circuit that monitors the input voltage and disconnects the input power if it exceeds 6.5V. This protects the device and the battery from damage due to over-voltage conditions.
  • Yes, the MCP73838T-FCI/MF can be used for charging lithium-ion batteries with different chemistries, such as LiCoO2, LiFePO4, and LiMnO2. However, the charging profile and termination voltage may need to be adjusted depending on the specific battery chemistry.
  • The STAT pin is a status output that indicates the charging status of the battery. It can be used to monitor the charging state, such as pre-charge, constant-current charging, and constant-voltage charging. The STAT pin can be connected to a microcontroller or other logic circuit to monitor the charging status and control the charging process.
  • The MCP73838T-FCI/MF has an internal thermal regulation circuit that monitors the device temperature and reduces the charging current if the temperature exceeds a certain threshold (typically 120°C). This helps to prevent overheating and damage to the device and the battery.
