DATASHEET ISL9205, ISL9205A, ISL9205B, ISL9205C, ISL9205D FN9252 Rev 4.00 Li-ion Battery Charger Dec 20, 2018 The ISL9205, ISL9205A, ISL9205B, ISL9205C, and ISL9205D Features are integrated single-cell Li-ion or Li-polymer chargers capable Complete charger for single-cell Li-ion/polymer batteries of operating at an input voltage as low as 2.5V. The low operating voltage allows the charger to work with a variety of Integrated pass element and current sensor AC adapters. No external blocking diode required The ISL9205 family operates as a linear charger when the AC Low component count and cost adapter is a voltage source. The battery is charged in a 25mV voltage accuracy over-temperature and input voltage standard Li-ion charge profile, that is, a Constant Current range phase followed by a Constant Voltage phase (CC/CV). The charge current during the Constant Current phase is 15mV voltage accuracy at room temperature determined by the external resistor connected to the IREF pin. Programmable charge current When the adapter output is a current-limited voltage source Programmable end-of-charge current (ISL9205) and the current limit is smaller than the programmed constant current of the IC, the ISL9205 operates as a pulse charger Charge current thermal foldback for thermal protection where the charge current is determined by the current limit of (Thermaguard) the AC adapter during the Constant Current phase. The Trickle charge for fully discharged batteries ISL9205 operates in a linear mode during the constant voltage Power presence and charge indications phase in both adapter cases. NTC interface (not available in some package options) The ISL9205 family incorporates Thermaguard, which protects the IC against over-temperature. If the die temperature rises Less than 3A leakage current off the battery when no input above a typical value of +100C, the thermal foldback power attached or charger disabled function reduces the charge current to prevent further Ambient temperature range: -40C to +85C temperature rise. The ISL9205 includes an external DFN, QFN packages temperature monitoring function (not available in some package options). A Negative Temperature Coefficient (NTC) Pb-free (RoHS compliant) thermistor is connected between the TEMP pin and GND to monitor the battery or ambient temperature. The ISL9205 also Applications includes a timer to set the time reference for various charge Mobile phones time limits. The timer is programmable with an external Bluetooth devices capacitor. Two logic inputs and two open-drain logic outputs are available for controlling the charger and indicating the PDAs charger status. The EN pin enables the charger. The TOEN pin MP3 players (available in the ISL9205) enables the timeout function so that the charge is terminated when the preset time limits have Stand-alone cradle or travel chargers been reached. The FAULT pin is an open-drain output that turns Other handheld devices on when a fault condition is encountered. The STATUS pin is also an open-drain output that turns on when the charger is Related Literature delivering current.
