Product Overview

The DS2715BZ+ from Maxim Integrated Products is a NiMH battery pack charge controller in 16 pin SOIC package. It is well suited for cost-sensitive charger applications where 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 comparator / transconductance amplifier for charge current regulation. It is configurable as a switched DC charger, linear current regulator or 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. A user selectable charge timer allows charge rates from 0.167C to 2C. FAST-CHARGE, TOPOFF, DONE modes are included for highly reliable, safe charging of NiMH cells. Discharge mode allows it to enter a low power sleep state while cell pack is being discharged.
  • Supply voltage range from 4.5V to 16.5V
  • FAST-CHARGE at up to a 2C rate
  • PRECHARGE and TOPOFF charge modes help cell conditioning
  • Load detection allows the DS2715 to enter low power sleep mode (<10µA) while cell pack is discharged
  • LED output displays charge state
  • Operating temperature range from -20°C to 85°C
  • Over-temperature, undertemperature, over-voltage detection prevents charging under unsafe conditions
