The DS2715 can determine the status of cell's state, and pre-condition the depleted cells before entering full charge mode of NiMH cells.
It cannot differentiate the cell chemistry and cannot terminate…
Yes,an amplifier circuit can be used across Rsense. But care must be taken in selecting the gain of external opamp to ensure that the internal amplifier will not saturate.
Note: External opamp may add…
The DS2715 uses the ratio of THM and VCBIAS which set the temperature thresholds. Table 3 in the datasheet shows the ratio of the voltage at THM to the voltage at V CBIAS rather than voltage and do give…
The battery voltage will still power the IC through a diode drop if the charge source is not connected. Cbias will have a voltage output. The IC will go to SUSPEND mode and reset the state machine when…
The DS2715 requires that voltage across the sense resistor exceeds V DCHG-SET which is 15mV maximum, 5mV minimum as specified in the datasheet. A common sense resistor value is 100mohms. This would require…
Q: When DS2715 evaluation board is used for charging the NiMH battery, the input is 6V and the output is connected to three NiMH battery packs with rated voltage of 3.6V and maximum charging voltage of…
Q: When using the DS2715 to charge a 9V 300mAH NIMH battery, the input power is 12VDC. We do not plan on using temperature detection. When the 12VDC is connected, the internal relay uses the 12VDC supply…
