Maxim Integrated MAX14641ETA+T Battery Charger IC

The Maxim Integrated MAX14641ETA+T is a highly integrated battery charger IC designed for charging single-cell lithium-ion (Li+) batteries. This compact, power-efficient component is an ideal solution for portable applications where space and power conservation are critical. The MAX14641ETA+T offers a programmable charging current, making it versatile for various battery capacities and applications.

The device operates over a wide input voltage range and can handle input voltages up to 6.6V, which is suitable for USB-powered devices and 5V adapter sources. It also incorporates a Smart Power Selector™ that allows the system to operate from a USB port or an adapter even when the battery is fully depleted.

The MAX14641ETA+T features an array of protection mechanisms to ensure safe charging and prolong battery life. These include overvoltage protection, thermal protection, and a battery temperature monitor that works in conjunction with an external thermistor to prevent charging if the battery temperature is outside of the safe operating range.

With its small package size (2mm x 2mm TDFN), the MAX14641ETA+T is particularly suited for space-constrained applications such as wearable devices, Bluetooth headsets, and other portable consumer electronics. It also supports a "ship mode" that minimizes battery drain when the device is in storage or not in use, thus extending the standby time.

Key features of the MAX14641ETA+T include:

• Programmable charge current for flexibility with various battery sizes
• Wide input voltage range suitable for USB and adapter charging
• Smart Power Selector™ for seamless transition between power sources
• Comprehensive protection circuitry for safe charging
• Compact TDFN package for space-constrained applications
• Ship mode for reduced power consumption during storage

Overall, the MAX14641ETA+T from Maxim Integrated is a robust and versatile charging solution that offers designers the efficiency, safety, and flexibility required for the next generation of portable electronics.
