Maxim Integrated DS2715BZ+ NiMH Battery Pack Charge Controller

The DS2715BZ+ from Maxim Integrated is a versatile and efficient charge controller designed specifically for NiMH (Nickel-Metal Hydride) battery packs. This advanced charge management device is ideal for applications requiring reliable battery performance and longevity, such as portable consumer electronics, medical devices, and industrial equipment.

The DS2715BZ+ offers a host of features that ensure the safe and effective charging of NiMH battery packs. It supports pack voltages of 1 to 10 cells in series, giving designers the flexibility to choose the appropriate battery configuration for their specific application needs. The device employs a negative delta V (-ΔV), temperature, and timed-termination algorithms to detect the full charge state, preventing overcharging and enhancing battery life.

One of the key advantages of the DS2715BZ+ is its ability to operate in either standalone mode or with a host microcontroller. In standalone mode, the device requires minimal external components, simplifying the design and reducing the overall bill of materials. For applications requiring more customized charge profiles or additional monitoring, the DS2715BZ+ can be interfaced with a host microcontroller through its I2C-compatible serial interface.

The charge controller also features precharge conditioning, which gently charges deeply discharged cells, and a top-off charge cycle to ensure the battery is fully saturated. Its automatic maintenance charge feature keeps the battery at peak readiness by periodically topping off the charge. Safety is a priority with the DS2715BZ+, and it includes over-temperature protection, charge-suspension on weak cells, and safety timer to prevent any charging mishaps.

Maxim Integrated's DS2715BZ+ comes in a compact surface-mount package, making it suitable for space-constrained applications. Its robust design ensures consistent performance across a wide range of temperatures, making it a reliable choice for portable and consumer devices that require dependable power management.

Overall, the DS2715BZ+ NiMH Battery Pack Charge Controller is a high-quality solution for any application that demands an efficient, safe, and flexible charging system for NiMH batteries.
