• Maximum input current up to 1.5A
• High efficiency: Greater than 93%,
• Low power dissipation: 10mW in no-load mode
• Wide input voltage range: 2.7V to 5.5V
• Low startup current: Typically only 20μA
• Voltage accuracy: ±138mV
• Reverse discharge protection: Prevents battery drain
• Temperature protection: Charges below 0°C
• Soft start charging increases usable battery life
• Charge status and operation status indicators

Application Field

The MP2624AGL-Z is perfect for use in mobile applications, such as mobile phones and PDAs, as well as any other device that requires a reliable, low power, and convenient charging solution. Because of its extremely low power consumption and wide input voltage range, the MP2624AGL-Z is ideal for applications where power dissipation, battery space, and weight are all a consideration.

Working Principle

The MP2624AGL-Z utilizes a high-efficiency switch mode PFM charging architecture. When powered on, it starts in the low-power, low current (typically only 20μA) signal waiting state. This minimizes the standby current consumption, so the battery can maintain a long life, while the device is waiting to be used.Once a battery is connected and powered up, the MP2624AGL-Z continually monitors the battery voltage and current, and adjusts the charging parameters accordingly. The PFM architecture automatically switches between standby and charging modes, allowing for an efficient charge without the need for complex control signals. There is also a voltage accuracy of ±138mV, and a wide input voltage range of 2.7V to 5.5V, for improved charging accuracy.The MP2624AGL-Z also has reverse discharge protection, which prevents the current from flowing back from the battery. This provides additional safety and extends battery life. The charger also incorporates an automatic temperature protection feature which prevents the charging of batteries below 0°C, increasing safety and maintaining battery health.

Conclusion

The MP2624AGL-Z is an excellent choice for mobile applications and devices that need a reliable, low power, and convenient charging solution. The features of the MP2624AGL-Z include maximum input current up to 1.5 A, high efficiency, low power dissipation, wide input voltage range, and voltage accuracy of ±138 mV. It also has reverse discharge protection, temperature protection and soft start charging, to ensure extended battery life.
