DS2762AE+

MAXIM INTEGRATED PRODUCTS  DS2762AE+  芯片, 电池监控器

The is a high-precision Li+ battery monitor with alert system in 16 pin TSSOP package. It is a 1-wire battery monitor integrated with single-cell protector. The device alerts system when current or temperature exceeds user-defined limits. This is a low power device with precise temperature, voltage, current measurement, non-volatile NV data storage and Li+ protection integrated in small package. The DS2762 is typically used for data-acquisition, information storage, capacity estimation, safety monitoring and cost-sensitive battery pack applications.
