ISL6255AHRZ-T - Renesas Electronics

Description: The ISL6255 and ISL6255A are highly integrated battery charger controllers for Li-Ion/Li-Ion polymer batteries. High efficiency is achieved by a synchronous buck topology and the use of a MOSFET, instead of a diode, for selecting power from the adapter or battery. The low side MOSFET emulates a diode at light loads to improve the light load efficiency and prevent system bus boosting. The constant output voltage can be selected for 2, 3 and 4 series Li-Ion cells with 0. 5% accuracy over temperature. It can a

ISL6255AHRZ-T Frequently Asked Questions (FAQs)

  • The maximum input voltage that the ISL6255AHRZ-T can handle is 28V, but it's recommended to keep it below 25V for reliable operation.
  • To ensure the ISL6255AHRZ-T is in a low-power state during shutdown, make sure the EN pin is pulled low and the VCC pin is decoupled from the input voltage source.
  • For optimal layout and placement, keep the input capacitors close to the VIN pin, and the output capacitors close to the VOUT pin. Also, keep the high-current paths short and away from sensitive analog signals.
  • The output voltage of the ISL6255AHRZ-T can be adjusted by changing the resistor divider ratio between the FB pin and the VOUT pin. Refer to the datasheet for the calculation formula and example values.
  • The thermal derating for the ISL6255AHRZ-T is based on the junction temperature (TJ) and the ambient temperature (TA). Refer to the datasheet for the thermal derating curve and calculation formula.
