Texas Instruments recommends that all integrated circuits be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage. ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications. DESCRIPTION (CONTINUED) The bq24616 controls external switches to prevent battery discharge back to the input and to connect the battery to the system using 6-V gate drives for system efficiency. The bq24616 features Dynamic Power Management (DPM). The DPM reduces battery charge current when the input power limit is reached to avoid overloading the AC adapter while supplying the load and the battery charger simultaneously. A highly-accurate current-sense amplifier enables precise measurement of input current from the AC adapter to monitor the overall system power. TYPICAL APPLICATION VIN=19V; 3-cell; Iadapter_limit=4A; Ipre-charge= Iterm=0.3A; 5 hour safety timer; Icharge=1.5A (0-10°C), 3A (10-60°C); VBAT=12.6V (0-45°C), 12.3V (45-50°C), 12.15V (50-60°C).
