SAA1501-Battery Level Indicator
Features · High integration to facilitate assembly in smart battery packs · Accurate charge and discharge account for large dynamic range of charge and discharge currents · Independently set charge and discharge efficiency · Minimum supply voltage of 2 V (2-cell operation)
·Battery temperature protection during charging ·Temperature controlled self-discharge ·Precise charge current regulation ·Two charge capacity display modes, LCD and LED.
The SAA1501T is intended to be used as a battery monitor in rechargeable battery and charge current control circuitry. The SAA1501T is designed to handle BiCMOS technology where the benefits of mixed bipolar and CMOS technologies are fully utilized to achieve high precision measurement digital signal processing in the same device. "The general function of the integrated circuit is the coulomb counter. During battery charging, the charging current and charging time are registered in the coulomb counter. During discharging, the discharging current and time are recorded. The battery charge amount can be displayed on the LCD screen or LED light bar at one time. Using the SAA1501T , smart battery or smart only battery powered systems can be easily designed with few external components.
