DS2715 - NiMH Battery Pack Charge Controller

Description

The DS2715 is well suited for cost-sensitive charger applications where the battery is either internal or in a unique battery pack.

It has been optimized for safe reliable charging of 1 to10 NiMH cells in series.

Features

  • Charges 1 to 10 NiMH Cells Fast Charges up to a 2C Rate Pre-Charge and Top-Off 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 Outputs Di.

It has been optimized for safe reliable charging of 1 to10 NiMH cells in series. The DS2715 has an internal gain block that can be selected as either a comparator or transconductance amplifier for charge current regulation. The DS2715 is configurable as a switched DC charger, a linear current regulator, or a switchmode current source. The DS2715 pre-conditions severely depleted cells are pre-conditioned before entering full charge mode. The DS2715 terminates full charge using the dT/dt technique. It requires an external thermistor for dT/dt detection.
