MCP73833-FCI/UN - Microchip

MCP73833-FCI/UN Frequently Asked Questions (FAQs)

• What is the maximum charging current that the MCP73833 can handle?
  The maximum charging current that the MCP73833 can handle is 1A, but it can be adjusted using an external resistor (RPROG) to a minimum of 100mA.
• How does the MCP73833 handle over-charge protection?
  The MCP73833 has a built-in over-charge protection feature that prevents the battery from being overcharged. It does this by monitoring the battery voltage and temperature, and terminating the charge cycle when the battery is fully charged.
• Can the MCP73833 be used for charging multiple batteries in parallel?
  Yes, the MCP73833 can be used for charging multiple batteries in parallel, but it requires an external circuit to balance the charge between the batteries.
• What is the purpose of the EN pin on the MCP73833?
  The EN (Enable) pin on the MCP73833 is used to enable or disable the charging function. When the EN pin is high, the charging function is enabled, and when it is low, the charging function is disabled.
• How does the MCP73833 handle battery temperature monitoring?
  The MCP73833 has a built-in thermistor input (TS pin) that allows it to monitor the battery temperature. It can adjust the charging current and voltage based on the battery temperature to prevent overheating or overcooling.
