Press Release Summary:
Suited for 1-cell and 2-cell Li-ion and Li-polymer based portable applications such as smartphones and tablet computers, Model ISL9220 minimizes charge time using synchronous PWM technology with integrated MOSFETs. Switching frequency of 1.2 MHz allows use of small external inductors and capacitors. Providing up to 2 A charge current and charge voltage accuracy of 0.5%, device offers programmable input current limiting along with programmable pre-charge and fast charge settings.
Original Press Release:
Intersil's New Battery Charger is Industry's Most Efficient and Versatile for 1-Cell and 2-Cell Li-Ion/Li-Polymer Batteries
Switched-Mode Battery Topology Delivers Maximum Charging Efficiency, Ultra-Low Power Dissipation with Low Leakage and Battery Temperature Monitoring
Milpitas, CA - Intersil Corporation (NASDAQ Global Select: ISIL) today added to its growing family of compact, fully integrated battery chargers by introducing the new ISL9220. The new device is based on a true switched-mode topology that ensures the highest operating efficiency and lowest power dissipation for 1-cell and 2-cell Li-ion and Li-polymer based portable applications such as smartphones and tablet computers.
The ISL9220 minimizes charge time while providing maximum power efficiency and heat reduction using synchronous pulse width modulation technology with integrated MOSFETs. The device's 1.2MHz switching frequency allows the use of small external inductors and capacitors. The device provides up to 2A charge current and charge voltage accuracy is 0.5 percent. Programmable input current limiting is included along with programmable pre-charge and fast charge settings.
Integrated overvoltage 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.
Pricing and Availability
The ISL9220 for 1-cell and ISL9220A for 2-cell batteries are both available now in compact 4mm x 4mm 20-lead TQFN packages. Pricing starts at $2.30 each in 1,000-piece quantities. For more information please visit: www.intersil.com/power/.
