ISL6292CCR3Z

The ISL6292CCR3Z belongs to ISL6292C, which is an integrated single-cell Li-ion orLi-polymer battery charger capable of operating with an inputvoltage as low as 2.4V. This charger is designed to work withvarious types of ac adapters. The ISL6292C operates as a linear charger when the acadapter is a voltage source. The battery is charged in aCC/CV (constant current/constant voltage) profile. The charge current is programmable with an external resistor upto 1.5A. The ISL6292C can also work with a current-limitedadapter to minimize the thermal dissipation, in which casethe ISL6292C combines the benefits of both a linear chargerand a pulse charger. The ISL6292C features charge current thermal foldback toguarantee safe operation when the printed circuit board isspace limited for thermal dissipation. Additional featuresinclude preconditioning of an over-discharged battery,automatic recharge, and thermally enhanced DFN package.

The features of ISL6292CCR3Z are (1)complete charger for single-cell Li-ion batteries; (2)very low thermal dissipation; (3)integrated pass element and current sensor; (4)no external blocking diode required; (5)1% voltage accuracy; (6)programmable current limit up to 1.5A; (7)charge current thermal foldback; (8)accepts multiple types of adapters; (9)guaranteed to operate at 2.65V after start up; (10)ambient temperature range: -20°C to 70°C; (11)thermally-enhanced DFN packages Pb-Free plus anneal available (RoHS compliant). The ISL6292CCR3Z can be used in handheld; devices including medical handhelds; PDAs, cell phones and smart phones; portable instruments, MP3 players; self-charging battery packs; stand-alone chargers; USB Bus-powered chargers.

The absolute maximum ratings of ISL6292CCR3Z are (1)supply voltage (VIN): -0.3 to 7V; (2)output pin voltage (BAT, VSEN, V2P8): -0.3 to 5.5V; (3)signal input voltage (TIME, IREF): -0.3 to 3.2V; (4) output pin voltage (STATUS, FAULT): -0.3 to 7V; (5)charge current: 1.6A; (6)ESD rating(human body model (Per MIL-STD-883 method 3015.7): 500V; machine model (per EIAJ ED-4701 method C-111): 200V); (7)recommended operating conditions(ambient temperature range: -20°C to 70°C; supply voltage, VIN: 4.3V to 6.5V.); (8)thermal information(maximum junction temperature (plastic package): 150°C; maximum storage temperature range: -65°C to 150°C; maximum lead temperature (soldering 10s): 300°C). (CAUTION: Stresses above those listed in "Absolute Maximum Ratings" may cause permanent damage to the device. This is a stress only rating and operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied.)
