DS2746G+

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.

• Supply voltage range is 2.5V to 4.5V

• 14bit bidirectional current measurement
• Current accumulation register resolution
• 11bit battery voltage measurement
• Two 11bit aux input voltage measurements
• Low power consumption
• Monitor 1-cell Li-ion, 3-cell NiMH battery
• Operating temperature range from -20°C to 70°C
