LTC4260IUH Frequently Asked Questions (FAQs)

  • The LTC4260IUH can be connected in parallel to support up to 8 hot swap controllers, allowing for a total of 16 channels of hot swap control.
  • To ensure that the power FET turns off during a fault condition, connect the FAULT pin to the gate of the power FET and set the fault response time using the FLT timer pin. This will guarantee that the power FET is turned off in case of an overcurrent or overvoltage fault.
  • To minimize EMI and noise, place the LTC4260IUH close to the power FET and keep the high-current paths short and wide. Use a solid ground plane and separate the analog and digital grounds. Also, use a shielded inductor and place it away from sensitive analog circuits.
  • The overcurrent threshold can be adjusted by selecting the appropriate sense resistor value (RS) and the response time can be adjusted by selecting the appropriate capacitor value (CT) for the FLT timer pin. Refer to the datasheet for the calculation formulas and examples.
  • Yes, the LTC4260IUH can be used for hot swapping batteries or other energy storage devices. However, additional circuitry may be required to handle the unique characteristics of batteries, such as voltage and current monitoring, and charging/discharging control.
