Charger chip is flexible about its
inputs
The ISL6299 is a fully integrated dual input (USB or cradle) charger for single-cell Li-ion/polymer batteries.
Featuring a high input voltage that offers a much more robust solution while alleviating the need for expensive overvoltage protection circuitry, Intersil's ISL6299 is a fully integrated dual input (USB or cradle) charger for single-cell Li-ion/polymer batteries The device has the highest input voltage rating (28V) in the industry and for flexibility features end-of-charge (EOC) programmability and EOC latch

Intersil has announced a DC/DC converter for RF power amplifiers that it claims is the industry's fastest startup from standby mode with very low current and excellent transient load response.
Intersil unveils integrated light/proximity sensor
Intersil has announced the release of the ISL29015 ambient and infrared light to digital converter with infrared LED driver.
EOC programming offers the ability to customise the charge function for the termination function for a particular application, and the EOC latch prevents false end-of-charge indications.
With the increased popularity of using USB for both data synchronisation and a source for charging, the ISL6299 offers OEMs the ultimate flexibility of providing end users both USB or desktop cradle/AC adapter charging with simultaneous connection.
Supporting applications in cellphones, smart phones, PDAs, MP3 devices, portable multimedia players, digital stills cameras and other portable industrial and test equipment, the ISL6299 is an ideal charger for smart handheld devices that need to communicate with a personal computer via the USB port.
It also protects portable devices from high input voltages and minimises the rise in temperature during charging.
Intersil's ISL6299 features maximum input voltages of 28V (cradle) and 7V (USB).
With the 28V cradle rating, low-cost (large-output-tolerance) adapters can safely be used.
When both inputs are powered, the cradle input is used to charge the battery.
The charge current is programmable for the cradle input with a small resistor.
The end-of-charge current for the cradle input is also programmable by another external resistor.
The ISL6299 is the fourth battery charger device Intersil has introduced in as many months and is evidence of the company's rapidly expanding product line.
The device is a complete battery charger, yielding a low component count solution and features that include programmable cradle charge current, charge indication, adapter present indication, and programmable end-of-charge (EOC) current with latch.
All these advanced features along with Intersil's Thermaguard technology for an added measure of thermal protection are delivered in the ISL6299 chip which is packaged in a tiny 3 x 3mm DFN package.
