Intersil Delivers World’s Most Highly-Integrated Battery Charger for Cell Phones, Bluetooth Devices and Portable Media Players
ISL9222A Combines Charger, Comparator and Logic on a Single Device, Providing Maximum Overvoltage Protection with Minimum Footprint
MILPITAS, CA, October 15, 2008 Intersil Corporation (NASDAQ Global Select: ISIL), a world leader in the design and manufacture of high-performance analog semiconductors, today announced the ISL9222A, a battery charger innovation designed to detect auxiliary and external power connections in mobile devices.
The ISL9222A is a high input, single cell, Li-Ion battery charger IC that incorporates a charger and digital logic (OR gate) into a single chip. This compact package enables customers to create small footprint solutions. The ISL9222As high level of integration and small size make it ideal for applications that require overvoltage protection, test fixture power detection or reverse blocking.
The ISL9222A accepts an input voltage up to 28V, but is disabled when the input voltage exceeds the overvoltage protection threshold (typically 7.2V) in order to prevent excessive power dissipation. The 28V rating eliminates the overvoltage protection circuit required with a low input voltage charger.
The charge current is user-programmable with an external resistor. When the battery voltage is lower than 2.55V, the charger preconditions the battery with 20% of the programmed charge current. The ISL9222A also features a thermal foldback function that protects the charger from over-temperature conditions.
The ISL9222A also features voltage accuracy is 1%. An indication pin (PPR) allows simple interface to a microprocessor or LED. When there is no adapter attached to the charger or when the charger is disabled, the ISL9222A draws less than 1 ìA leakage current from the battery.
Pricing and Availability
The
ISL9222A is available now in 8-lead TDFN packages, priced at $1.40 each in
1,000-unit quantities.
