LTC4120IUD#PBF Frequently Asked Questions (FAQs)

  • The maximum charging current of the LTC4120 is 2A, but it can be limited to a lower value by setting the CHG pin to a lower voltage.
  • The LTC4120 has a built-in overvoltage protection (OVP) circuit that disconnects the input power when the input voltage exceeds 22V. The OVP threshold can be adjusted by connecting a resistor divider network to the OVP pin.
  • Yes, the LTC4120 can be used for charging multiple batteries in parallel. However, the total charging current should not exceed the maximum rating of 2A, and the batteries should be identical and balanced to ensure proper charging.
  • The LTC4120 has a built-in thermistor input (TS pin) that allows for battery temperature monitoring. The thermistor input can be connected to a thermistor or a temperature sensor to monitor the battery temperature and adjust the charging current accordingly.
  • The CHG pin on the LTC4120 is used to set the charging current. By connecting a resistor to the CHG pin, the charging current can be set to a specific value between 50mA and 2A.
