The BQ2018TS-E1 from Texas Instruments is a multifunction charge/discharge counter IC designed for battery management applications. It works in conjunction with an intelligent host controller to provide accurate state-of-charge information for multi-chemistry rechargeable batteries.
This IC measures voltage drops across a low-value sense resistor to calculate charge and discharge counts. It features internal offset calibration for improved accuracy and an internal temperature sensor for self-discharge estimation. The BQ2018TS-E1 includes 1024 bits of NVRAM for configuration and status information.
With a single-wire HDQ serial interface, the device operates in dual modes: an active mode consuming less than 80µA and a sleep mode consuming less than 10µA. It is packaged in an 8-pin TSSOP, making it suitable for integration into battery packs. The operating temperature range is -20°C to 70°C.
Key features include resolution of signals less than 12.5µV, an internal timebase eliminating external components, and an REG output for low-cost microregulation. The BQ2018TS-E1 is designed for applications requiring precise battery monitoring and state-of-charge estimation.
