The high input voltage range with input • 1% Battery Voltage Regulation Accuracy over-voltage protection supports low-cost unregulated • Up to 800mA Charge Current with 10% Charge adapters. The input voltage regulation loop with Current Accuracy programmable input voltage regulation threshold • Thermal Regulation Protection for Output make it suitable for charging from alternative power Current Control sources, such as solar panel or inductive charging pad. • Low Battery Leakage Current • BAT Short-Circuit Protection The IC has a single power output that charges the battery. A system load can be placed in parallel with • NTC Input Monitoring the battery as long as the average system load does • Built-In Safety Timer With Reset Control not keep the battery from charging fully during the 10 • Status Indication – Charging/Power Present hour safety timer. • Available in Small 2mm × 3mm SON-10 The battery is charged in three phases: conditioning, Package constant current and constant voltage. In all charge phases, an internal control loop monitors the IC junction temperature and reduces the charge current if an internal temperature threshold is exceeded. 1 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
