Maxim Integrated MAX713ESE+ NiCd/NiMH Battery Charger
The MAX713ESE+ from Maxim Integrated is a sophisticated and highly integrated solution for charging Nickel-Cadmium (NiCd) and Nickel-Metal Hydride (NiMH) batteries. Designed for precision and efficiency, this charger controller is ideal for portable electronics where space is at a premium and battery life is of utmost importance.
Featuring a switch-mode design, the MAX713ESE+ offers a high-frequency operation that enables the use of a smaller inductor and capacitors compared to traditional linear chargers. This leads to a reduction in the overall size of the charging circuit, making it perfect for compact devices such as handheld radios, power tools, and small appliances.
The device operates in a fast-charge mode that can quickly bring NiCd or NiMH batteries to full capacity. It does so by monitoring the voltage and temperature of the batteries to prevent overcharging and overheating, which can extend the life of the batteries. Once the batteries are fully charged, the MAX713ESE+ automatically transitions to a trickle-charge mode, maintaining the batteries at full charge without overcharging, which is crucial for battery health and safety.
One of the key features of the MAX713ESE+ is its programmability. Users can set the fast-charge current, the charge termination voltage, and the trickle-charge current by selecting external resistors. This flexibility allows the charger to be optimized for a wide range of battery sizes and chemistries.
The MAX713ESE+ comes in a 16-pin narrow SO package, which is suitable for surface-mount technology (SMT), and operates over the extended industrial temperature range of -40°C to +85°C. Its robust design includes safety features such as battery reverse-voltage protection and a thermal-shutdown mechanism to protect the charging device and batteries from extreme conditions.
With its combination of compact design, fast and intelligent charging, and programmability, the MAX713ESE+ is an excellent choice for anyone looking to integrate a reliable battery charging solution into their electronic projects or products.
