MAXIM INTEGRATED PRODUCTS DS2746G+ BATT MONITOR, 4.5V, TDFN-10

Обзор продукта

The DS2746G+ is a Low-Cost, 2-wire battery monitor with ratiometric A/D inputs in 10 pin TDFN package. This device provides system-side battery capacity monitoring in cost-sensitive applications. It monitors Voltage, bidirectional current and accumulated current measurement data which is provided to host processor over a 2-wire interface. Offset bias and offset blanking features greatly enhance the accuracy of the coulomb counter. 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.
