The MAX712ESE is an integrated circuit (IC) component designed for battery charging applications. It is a dedicated single-cell NiMH and NiCd battery fast-charging controller. This IC regulates and controls the charging process, ensuring optimal charging and preventing overcharging, which can lead to reduced battery life and damage.
The MAX712ESE offers several key features that make it suitable for battery charging applications. Firstly, it includes an integrated microcontroller, which allows the device to accurately monitor and control the charging process. This microcontroller provides advanced algorithms to optimize charging times and ensure proper termination when the battery reaches its full capacity.
To facilitate the charging process, the MAX712ESE supports voltage or temperature sensing options. It can monitor the battery voltage and adjust the charging current accordingly to prevent damage due to overcurrent. Alternatively, it can utilize temperature sensing to control the charging process by automatically adjusting the charging current based on the battery temperature. This feature is particularly useful to prevent overheating of the battery during the charging cycle.
The IC includes an onboard thermal regulating circuitry that prevents excessive heat generation during charging. It incorporates a thermal foldback feature that reduces the charging current when the temperature rises above a predetermined threshold. This protects the battery from overheating and extends its overall lifespan.
Furthermore, the MAX712ESE supports a trickle-charge mode, allowing a low current to flow continuously after the charging process is complete
