Maxim Integrated MAX713EPE NiCd/NiMH Battery Charger

The MAX713EPE is a highly integrated charge-management IC designed by Maxim Integrated to efficiently charge Nickel-Cadmium (NiCd) and Nickel-Metal Hydride (NiMH) batteries. This sophisticated charging solution is ideal for portable electronic devices, power tools, and backup power systems that require reliable battery performance.

Engineered with precision in mind, the MAX713EPE offers a fast-charge control algorithm that can safely recharge batteries to their full capacity in minimal time. This is achieved through a combination of negative delta Voltage (-ΔV) fast-charge termination, charge timeout, and top-off charging, ensuring that batteries are charged quickly without overcharging or damaging the cells.

The MAX713EPE features a programmable charge current through an external resistor, which allows users to tailor the charging profile to the specific needs of their battery pack. Additionally, the device supports a wide input voltage range, making it versatile for various applications and power sources.

Temperature monitoring is another critical aspect of the MAX713EPE's design. The IC includes a thermistor input that prevents charging if the battery temperature is outside of a specified safe range. This safety feature helps to avoid thermal runaway conditions and extends the life of the battery.

Moreover, the MAX713EPE incorporates an automatic trickle-charge feature, which maintains the battery at full charge without overcharging when left connected to the charger for an extended period. This maintenance charge ensures that the battery is always ready for use while preserving its overall health and longevity.

Available in a 16-pin DIP (Dual In-line Package), the MAX713EPE is easy to integrate into existing and new designs. Its compact form factor makes it suitable for space-constrained applications, and its robust construction ensures reliable operation across a broad temperature range.

For designers looking for a reliable and efficient battery charging solution, the Maxim Integrated MAX713EPE offers a comprehensive set of features that make it an excellent choice for managing the power needs of NiCd and NiMH battery packs.
