The SY6302 is an ultra-low power battery gauge for 1-series Li-ion battery packs.
The IC integrates a flash-programmable 32-bit CPU, allowing both battery parameters and firmware to be upgraded online via I2C.
It provides precision measurements of current, voltage and temperature. It supports both high-side and low-side current sensing.
The temperature of the battery pack is measured using an internal temperature sensor or an external thermistor.
The SY6302 tracks battery operating conditions and performs an algorithm to calculate the SOC(state of charge).
Accurate current sensing is not essential?for this algorithm.
The SY6302 is available in packages of 2mm x 3mm DFN8 and 1.43mm x 1.43mm CSP9 (0.5mm pitch).
