● Exceptional Efficiency

The MP2615GQ-Z maximizes its efficiency by operating at up to 99% duty cycle. This is especially useful when charging a battery that is near to the input voltage, as it ensures that charging remains rapid and efficient.

● Adjustable Charging Current

This charger allows you to program the charging current, giving you complete control over the charging process. It can provide a charging current of up to 2A, making it suitable for a wide range of battery kinds and capacities.

● Controlling Voltage Accurately

It is critical to have great precision in battery charging. The MP2615GQ-Z has an impressive 0.75% accuracy in full battery voltage regulation, guaranteeing that your battery is charged precisely.

● Choosing a Battery Voltage

For establishing the full battery voltage, this charger offers two voltage options: 4.1V/cell and 4.2V/cell. This function is required for compatibility with various battery chemistries and charging needs.

● Power Switches Built-In

The MP2615GQ-Z has fully integrated power switches, which simplifies the design and eliminates the need for additional external components. This integration simplifies the charging procedure as a whole.

● Compensation for Internal Loops

Internal loop compensation is built within the charger, which is critical for consistent and reliable charging performance. It aids in maintaining precise control over the charging process.

● Protection Against Reverse Blocking

One of the MP2615GQ-Z’s notable characteristics is its integrated reverse blocking protection. This eliminates the requirement for an external reverse blocking diode, simplifying and saving space in the design.

● Depleted Battery Preconditioning

The charger has a preconditioning capability, which is especially useful for completely exhausted batteries. It ensures that even the most deeply drained batteries can be charged safely and effectively.

● Indicator of Charging Operation

A charging operation indicator allows users and manufacturers to monitor the charging process. This visual feedback improves the user experience while also providing useful information about the charger’s status.

● Timer for Safety

The MP2615GQ-Z includes a programmable safety timer, which improves charging safety. This timer aids in the prevention of overcharging and the associated safety issues.

● Thermal Shutdown Safety

Thermal shutdown prevention is included into the charger to protect it from overheating. This safeguard guarantees that the charger functions within safe temperature ranges.

● Overcurrent Defense

In the event of an overcurrent problem, the charger includes cycle-by-cycle overcurrent protection, which helps avoid damage to the charger, battery, or connected devices.

● Temperature Monitoring and Protection for Batteries

During the charging procedure, the temperature of the battery is continuously checked. This function improves safety by preventing overcharging and overheating, both of which can be damaging to the battery.

The MP2615 operates as a peak current mode controlled charger for 1- or 2-cell lithium-ion and lithium-polymer batteries. It employs a three-phase charging cycle (TC → CC → CV) for efficient and accurate charging:

  • Trickle-Charge Mode (TC): When the battery voltage falls below a certain level, the charger employs trickle charge to gradually increase the voltage. If a timer is triggered, charging will halt.
  • Constant Current Mode (CC): When the battery voltage exceeds a certain threshold, the charger enters a constant current mode, which allows for faster charging.
  • Constant Voltage Mode (CV): When the battery is nearing capacity, the charger enters constant voltage mode to manage the voltage.

Charge termination and auto-recharge are two of the charger’s safety features. The charger stops charging if the charge current falls below a certain threshold during the constant voltage phase. If the battery voltage falls, recharging occurs automatically.

The MP2615 uses a constant off-time (COT) charge mode to achieve a 99% duty cycle and retain high efficiency. It also indicates charge status through the CHGOK and ACOK pins.

In conclusion, the MP2615 enables efficient, accurate, and safe charging of lithium-ion and lithium-polymer batteries, making it an important component in a variety of applications.


The MP2615GQ-Z represents the pinnacle of high-efficiency battery charging technology, offering a remarkable blend of versatility and cutting-edge safety features for a wide spectrum of portable electronic devices. With its remarkable capacity to deliver high charging currents, maintain constant current and voltage regulation, all within a sleek and compact design, it unquestionably emerges as an indispensable choice to ensure our modern devices remain powered, efficient, and secure.

As technology continues its relentless march forward, the MP2615GQ-Z solidifies its role as an essential component in the realm of power management.
