DescriptionThe ISL6299IRZ belongs to ISL6299, which is a fully integrated low-cost single-cell Li-ion or Li-polymer battery charger. The charger ISL6299IRZ accepts two power inputs, normally one from a USB (Universal Serial Bus) port and the other from a desktop cradle. The ISL6299IRZ is an ideal charger for smart handheld devices that need to communicate with a personal computer via USB. The ISL6299IRZ features 28V and 7V maximum voltages for the cradle and the USB inputs respectively. Due to the 28V rating for the cradle input, low-cost, large output tolerance adapters can be used safely. 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 charger incorporates Thermaguard™ which protects the IC against over temperature. If the die temperature rises above a typical value of 100°C, a thermal foldback function reduces the charge current automatically to prevent further temperature rise. The charger preconditions the battery with low current when the battery voltage is below 2.6V. The charger has two indication pins. The PPR (power present) pin outputs an open-drain logic LOW when either the cradle or the USB input power is attached. The CHG (charge) pin is also an open-drain output that indicates a logic LOW when the charge current is above a minimum current level. When the charge current is below the minimum current, the CHG pin indicates a logic HIGH signal and the status is latched. The latch will be reset at one of these events: (1) the part is disabled and re-enabled; (2) the selected input source has been removed and re-applied, (3) The USBON turns LOW, or (4) The BAT pin voltage falls below the CV mode threshold. It can be used in smart handheld devices; cell phones, PDAs, MP3 players; digital still cameras; handheld test equipment.
