2 / 38 page DESCRIPTION (CONTINUED) ABSOLUTE MAXIMUM RATINGS (1) bq24072, bq24073 bq24074, bq24075 SLUS810A – SEPTEMBER 2008 – REVISED DECEMBER 2008...................................................................................................................................... www.ti.com These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates. Additionally, the regulated system input enables instant system turn-on when plugged in even with a totally discharged battery. The power-path management architecture also permits the battery to supplement the system current requirements when the adapter cannot deliver the peak system currents, enabling the use of a smaller adapter. The battery is charged in three phases: conditioning, constant current, and constant voltage. In all charge phases, an internal control loop monitors the IC junction temperature and reduces the charge current if the internal temperature threshold is exceeded. The charger power stage and charge current sense functions are fully integrated. The charger function has high accuracy current and voltage regulation loops, charge status display, and charge termination. The input current limit and charge current are programmable using external resistors.

T - taped and reeled in quantities of 250 devices per reel. (2) This product is RoHS compatible, including a lead concentration that does not exceed 0.1% of total product weight, and is suitable for use in specified lead-free soldering processes. In addition, this product uses package materials that do not contain halogens, including bromine (Br) or antimony (Sb) above 0.1% of total product weight. over the 0°C to 125°C operating free-air temperature range (unless otherwise noted) VALUE UNIT IN (with respect to VSS) –0.3 to 28 V BAT (with respect to VSS) –0.3 to 5 V VI Input Voltage OUT, EN1, EN2, CE, TS, ISET, PGOOD, CHG, ILIM, TMR, –0.3 to 7 V ITERM, SYSOFF, TD (with respect to VSS) II Input Current IN 1.6 A OUT 5 A IO Output Current (Continuous) BAT (Discharge mode) 5 A BAT (Charging mode) 1.5(2) A Output Sink Current CHG, PGOOD 15 mA TJ Junction temperature –40 to 150 °C Tstg Storage temperature –65 to 150 °C (1) Stresses beyond those listed under absolute maximum ratings may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under recommended operating conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. All voltage values are with respect to the network ground terminal unless otherwise noted. (2) The IC operational charging life is reduced to 20,000 hours, when charging at 1.5A and 125°C. The thermal regulation feature reduces charge current if the IC’s junction temperature reaches 125°C; thus without a good thermal design the maximum programmed charge current may not be reached. 2 Submit Documentation Feedback Copyright © 2008, Texas Instruments Incorporated Product Folder Link(s): bq24072 bq24073 bq24074 bq24075 |
