MCP73871T-4CAI/ML Frequently Asked Questions (FAQs)

  • The maximum charging current that can be set using the ISET pin is 1.5A. However, it's recommended to limit the charging current to 1A to ensure reliable operation and to prevent overheating.
  • The MCP73871T-4CAI/ML 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.
  • No, the MCP73871T-4CAI/ML is designed to charge a single lithium-ion battery. Charging multiple batteries in parallel would require a more complex charging circuit and is not recommended.
  • The STAT pin is a status output that indicates the charging status of the battery. It can be used to monitor the charging process and to detect when the battery is fully charged. The STAT pin is an open-drain output, so it requires an external pull-up resistor to VCC.
  • The MCP73871T-4CAI/ML does not have an internal temperature sensor, but it can be connected to an external thermistor (such as the NTCALUG01A103K) to monitor the battery temperature. The device will adjust the charging current based on the battery temperature to prevent overheating.
