Battery Charge Controller NiMH 28mA 0V to 16.5V 16-Pin SOIC N, DS2715Z+, Maxim Integrated

The DS2715 is well suited for cost-sensitive charger applications where the battery pack is either internal or external to the application. It has been optimized for safe and reliable charging of 1 to 10 NiMH cells in series. The internal gain block can be selected as either a comparator or transconductance amplifier for charge current regulation. This makes the DS2715 configurable as a switched DC charger, a linear current regulator, or a switch-mode current source. The DS2715 pre-conditions severely depleted cells before entering full charge mode. It terminates full charge using the dT/dt technique, which requires an external sensing thermistor. Over-temperature, under-temperature, and over-voltage detection prevents charging under unsafe conditions. A user selectable charge timer allows charge rates from 0.167°C to 2°C. FAST-CHARGE, TOPOFF and DONE modes are included for highly reliable, safe charging of NiMH cells. Discharge mode allows the DS2715 to enter a low power sleep state while the cell pack is being discharged.

  • Charges 1 to 10 NiMH Cells
  • FAST-CHARGE up to a 2°C Rate
  • PRECHARGE and TOPOFF Charge Modes Help Cell Conditioning
  • Load Detection Allows the DS2715 to Enter Low Power Sleep Mode (Less than 10µA) while the Cell Pack is Discharged
  • dT/dt Charge Termination Eliminates Cell Charge Stress
  • Monitors Voltage, Temperature, and Time for Safety and Secondary Termination
  • Regulates Current through Either Linear Control or Switch-Mode Control
  • LED Output Displays Charge State
  • Small 16-Pin SO Package
