The MAX8671CETL+T is an integrated, single-chip solution that offers superior protection and high efficiency in a small package. It integrates a linear charger controller, charger enable logic, battery temperature monitor, overvoltage protection, overcurrent protection, and undervoltage lockout circuit with a single programmable current-limited selector switch and a synchronous voltage-mode buck converter. The MAX8671CETL+T is available in a 28-pin TQFN-EP package and operates over a wide input and output voltage range, making it suitable for a variety of systems, from personal electronics to industrial and automotive applications.

The MAX8671CETL+T has an integrated current-limited selector switch. The selector switch allows the charger to limit the input current from the AC or DC power source or from the battery from an external power source, such as a USB port. This allows the MAX8671CETL+T to accurately monitor the input current and maintain it below a predetermined level. The current-limited selector switch also allows for accurate detection of battery voltage. The MAX8671CETL+T also has a built-in temperature monitor which detects die temperature, battery temperature, and external ambient temperature using multiple temperature sensors. This allows the MAX8671CETL+T to monitor and protect the battery from excessive temperature conditions.

The MAX8671CETL+T offers a wide range of features that make it suitable for a range of applications. It has an input voltage range from 4.5V to 20V, an output voltage range from 0.5V to 2.5V, and a maximum output current of 1A. It has integrated overvoltage protection, overcurrent protection, and undervoltage lockout circuits. It also includes thermal protection, reverse current protection, and fast charge termination algorithm. All of these features make the MAX8671CETL+T suitable for use in applications such as cell phones, portable media players, digital still cameras, and other high-demand power applications.

The MAX8671CETL+T has a highly integrated charge controller which enables fast charging and provides maximum flexibility and protection. The charge controller is capable of accurately setting the output voltage and current limit thresholds to ensure maximum charge rate and protection. The charger automatically detects the battery type and adjusts its charging parameters accordingly. This allows for a fast, safe, and efficient charge. The charge controller also has a specific algorithm for fast and intelligent charging. It monitors the battery voltage, current and temperature during charging to ensure an optimal charge condition.

The MAX8671CETL+T is well suited for a variety of applications requiring fast charging and high efficiency. The device is well-suited for use in portable systems, such as smartphones and other handheld devices. Its integrated protection and current-limited selector switch allow for accurate monitoring of input and output voltage, current, and temperature. Its operating range, small size, and fast charging capabilities make the MAX8671CETL+T the ideal solution for high-demand power applications.
