PRODUCT PREVIEW www.ti.com bq24212 SLUSAL3 – AUGUST 2011 800mA, Single-Input, Single Cell Li-Ion Battery Solar Charger Check for Samples: bq24212 FEATURES 1 Input Voltage Dynamic Power Management Feature (VBUS_DPM) Selectable Battery Tracking Mode to Maximize the Charge Rate from Solar Panel Using DPM Feature Load Mode to Support Loads Connected at VBUS Pin 20V Input Rating, with Over-Voltage Protection (OVP) 1% Battery Voltage Regulation Accuracy Up to 800mA Charge Current with 10% Charge Current Accuracy Thermal Regulation Protection for Output Current Control Low Battery Leakage Current BAT Short-Circuit Protection NTC Input Monitoring Built-In Safety Timer With Reset Control Status Indication – Charging/Power Present Available in Small 2mm × 3mm SON-10 Package APPLICATIONS Smart Phones PDAs MP3 Players Low-Power Handheld Devices Auxiliary Solar Chargers DESCRIPTION The bq24212 is a highly integrated Li-ion linear charger targeted at space-limited portable applications. The high input voltage range with input over-voltage protection supports low-cost unregulated adapters. The input voltage regulation loop with programmable input voltage regulation threshold make it suitable for charging from alternative power sources, such as solar panel or inductive charging pad. The IC has a single power output that charges the battery. A system load can be placed in parallel with the battery as long as the average system load does not keep the bat...
