MAX14746BEWA+ is a battery charger IC designed for use in portable electronic systems, including cellular phones, digital still cameras, tablets, and e-books. It is an advanced, low-power device that features a fully integrated charge pump, power path management and a battery gauger. The MAX14746BEWA+ is able to directly replace board-level solutions, minimizing parts count and design time.

The charger IC is an integrated circuit consisting of several blocks, including a charge pump, power path manager, and a battery gauger. It works by monitoring the input voltage and current, then using a differential amplifier to detect when the charge rate is too high or low. Once the correct charging level has been reached, charging is controlled by a built-in PWM controller. The device also integrates a real-time battery monitoring system with separate accurate voltage, current and temperature measurements.

The MAX14746BEWA+ is designed to efficiently charge Li-Ion and Li-Polymer batteries. It does so by employing a coil-less step-up charge pump to boost the input voltage to the proper voltage for charging the battery. In addition, the device uses a buck-boost power path manager, which is independent of the charge pump, to ensure that the battery is supplied with the correct voltage and current while it is being charged. This allows it to easily be used in combination with other power sources, such as USB, AC adapters, or solar power.

The MAX14746BEWA+ also features an advanced safety timer that detects when the charger has been operating for too long and shuts it down, to prevent overcharging or overheating. In addition, the device features automatic safety features that shut down the charging process in the event of a temperature or voltage anomaly.

The MAX14746BEWA+ is the perfect IC for any design engineer looking to minimize board space, parts count and development time. It is especially useful for portable applications that require efficient charging of Li-Ion or Li-Polymer batteries, as it can be easily integrated with multiple power sources. Its advanced safety features make it an ideal choice for applications where battery safety is a priority.
