Intersil’s ISL9220 is a fully integrated battery charger based on a true switched-mode topology that ensures high operating efficiency and low power dissipation for 1-cell and 2-cell Li-ion and Li-polymer-based portable applications. Its 1,2 MHz switching frequency allows the use of small external inductors and capacitors. The IC provides up to 2 A charge current and charge voltage accuracy is 0,5%. Programmable input current limiting is included, along with programmable pre-charge and fast charge settings. Integrated over-voltage protection on the adapter/USB power input protects both the battery and circuitry from damage due to excessive voltage on the input. A programmable safety timer is provided to terminate charging if the battery fails to charge in the programmed period. The ISL9220 can also monitor the battery temperature and discontinue charging if the temperature becomes unsafe.
