MCP73837-FJI/UN Frequently Asked Questions (FAQs)

  • The maximum input voltage that the MCP73837 can handle is 7V. However, it's recommended to keep the input voltage below 6V to ensure reliable operation and to prevent damage to the internal voltage regulator.
  • The charge current of the MCP73837 can be configured by selecting the appropriate resistor value for the RPROG pin. The datasheet provides a table to help select the correct resistor value based on the desired charge current.
  • The EN pin is an active-high enable input that allows the user to turn the charger on or off. When the EN pin is high, the charger is enabled, and when it's low, the charger is disabled. This pin can be used to implement power management or to turn off the charger when not in use.
  • The MCP73837 has a built-in battery detection circuit that can detect when a battery is inserted or removed. When a battery is inserted, the charger will start charging the battery. When the battery is removed, the charger will enter a low-power standby mode to conserve power.
  • The MCP73837 uses a constant-current, constant-voltage (CCCV) charging profile. It first charges the battery with a constant current until the battery voltage reaches a certain threshold, and then switches to a constant voltage mode to trickle charge the battery.
