Ensuring overvoltage protection, Model ISL9301 single-cell Li-ion/polymer battery charger features high input voltage and integrated overvoltage protection circuit which enables automatic shutdown feature when input voltages exceed 10.5 V during normal operation. With multiple power paths, one for charging and another for device operation, it enables simultaneous charging and powering of any handheld device operating from single cell Li-ion battery.
Original Press Release:
High-Input Voltage Charger Provides Superior Overvoltage Protection and Power Path Management Functions
Intersil's ISL9301 - a 3mm x 3mm Single-cell Li-ion/Polymer Battery Charger - Combines 28V Maximum Input Voltage, Power Path Management and Integrated Battery Disconnect Switch.
MILPITAS, CA, May 22, 2008 - Intersil Corporation (NASDAQ Global Select: ISIL), a world leader in the design and manufacture of high-performance analog semiconductors, today announced the release of the ISL9301. This high-input voltage battery charger can safely handle input voltages up to 28V.
Superior overvoltage protection is achieved through the ISL9301's high input voltage and integrated overvoltage protection circuit which enables an automatic shutdown feature when input voltages exceed 10.5V during normal operation.
The ISL9301 also features dynamic power path management to optimize charge and system currents. With multiple power paths - one for charging and another for device operation - the ISL9301 enables simultaneous charging and powering of any handheld device operating from a single cell Li-ion battery. This feature allows immediate operation of cell phones, PDAs and MP3 players even when the battery is fully discharged.
The power path feature in the ISL9301 also allows the charge to terminate when the battery is full while continuing to supply the system with the requested power. This minimizes unnecessary charge and discharge cycles and improves battery life.
The ISL9301 also extends a battery disconnect function that prevents any leakage or battery drain when the handheld device is not in use. This feature greatly helps to maximize battery life.
Pricing and Availability
The ISL9301 is available now in a 10-lead DFN package and is priced at $1.87 in 1,000-unit quantities.
