The BQ2018TS-E1TR from Texas Instruments is a low-cost, multi-chemistry charge/discharge counter peripheral IC. It functions as a battery monitor, providing state-of-charge information for rechargeable batteries when used with an intelligent host controller.
The device measures voltage drops across a sense resistor to determine battery status. It offers a high-speed 1-wire interface (HDQ) and operates with low power consumption, featuring dual modes: operating at less than 80uA and sleep mode at less than 10uA. The BQ2018TS-E1TR includes 1024 bits of NVRAM for configuration and data storage.
Packaged in an 8-pin TSSOP, this IC is suitable for battery pack integration. It operates within a temperature range of -20°C to 70°C. The BQ2018TS-E1TR is designed to work with an intelligent host controller, which is responsible for managing registers and determining battery state-of-charge information.
Key features include internal offset calibration for improved accuracy, an internal temperature sensor for self-discharge estimation, and an integrated timebase eliminating the need for external components. The REG output supports low-cost microregulation.
