PMIC - Battery Chargers

A Battery Charger is a device used to put energy into a secondary cell or rechargeable battery by forcing an electric current through it. Chargers are usually designed for a specific chemistry and type of battery, and must be used carefully in order to avoid damaging it. The most common type of charger is the constant current/constant voltage (CCCV) charger. It is best suited for Ni-Cad (nickel-cadmium) and NiMH (nickel metal-hydride) chemistries, and is suitable for other chemistries as well. The MAX712CSE+ is a CCCV charger designed for Ni-Cd, NiMH, PB, Li-Ion, and Lead Acid batteries.

The MAX712CSE+ is a high-efficiency, two-cell charger IC designed to charge two nickel-based or lead-acid batteries in series. The IC is capable of detecting and charging different battery types and chemistries, including Nickel-Cadmium (Ni-Cd), Nickel-Metal Hydride (Ni-MH), PB, Li-Ion and Lead Acid batteries. It is optimized for low power consumption and accurate charge control, making it ideal for applications where battery performance and life are paramount. The MAX712CSE+ Features quick charge and trickle charge operation, adjustable charge rate, and fully adjustable charge and discharge cycle times. It also has a Charge Complete alarm, and includes a low-battery alarm and charge end indicator, as well as a temperature sensor input.

The MAX712CSE+ works by monitoring the voltage of each cell during charge and discharge. During charging, the charger monitors the voltage of each cell, and when the voltage reaches a certain threshold, the charge rate is reduced, allowing the cells to charge at a slow and steady rate. The charger then continues to adjust the current as needed to ensure safe, effective charging. During discharge, the charger monitors the voltage of each cell and when the voltage drops below a certain threshold, the charger automatically switches to trickle charge. This allows the cells to maintain their charge, preventing over-discharge and improving battery performance.

The MAX712CSE+ can be used in a wide range of applications, from automotive charging systems to portable power packs, and is suitable for use in a variety of power sources, including solar, mains power and automotive. Its optimized design makes it ideal for low-power applications and its adjustable parameters allow for tailored operation. The MAX712CSE+ can provide superior charge control and efficiency compared to other battery charging solutions, making it an ideal choice for any application where battery performance and life are a priority.
