ISL6256AHAZ-T - Renesas Electronics

Description: The ISL6256, ISL6256A is a highly integrated battery charger controller 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 also

ISL6256AHAZ-T Frequently Asked Questions (FAQs)

  • Renesas provides a recommended PCB layout in the ISL6256AHAZ-T evaluation board user manual, which includes guidelines for thermal vias, copper pours, and component placement to minimize thermal resistance and ensure reliable operation.
  • Renesas provides a compensation calculator tool on their website, which helps designers optimize the compensation network for the voltage regulator based on their specific application requirements. Additionally, the datasheet provides general guidelines for compensation network design.
  • While the datasheet specifies the maximum input voltage rating, it does not explicitly state the maximum allowed input voltage ripple. According to Renesas' application notes, the recommended input voltage ripple is less than 1% of the input voltage to ensure stable operation.
  • Yes, the ISL6256AHAZ-T is rated for operation up to 125°C junction temperature. However, designers should ensure that the device is properly derated for temperature and that the PCB and surrounding components can withstand the high temperatures.
  • Renesas provides a troubleshooting guide in the ISL6256AHAZ-T datasheet, which covers common issues and their possible causes. Additionally, designers can consult Renesas' application notes and technical support resources for further assistance.
