Description
The DS2746 provides system-side battery capacity monitoring in cost-sensitive applications.
Voltage, bidirectional current, and accumulated current measurement data is provided to the host processor over a 2-wire interface.
Features
- greatly enhance the accuracy of the coulomb counter. In addition, the DS2746 has two auxiliary A/D inputs to sample the pack identification resistor, thermistor, or other voltage source. The results are reported as a ratiometric fraction of the supply voltage eliminating error related to the supply. The DS2746 reduces the total power consumption of the measurement circuit by enabling the resistor dividers, through the VOUT pin, only while measurements are made. When the system is inactive, a low.
