MAX745EAP Description

Short technical summary and product information.

The MAX745EAP from Analog Devices is a versatile switch-mode battery charger designed for lithium-ion (Li+) battery packs. It efficiently charges 1 to 4 Li+ cells, providing a regulated charging current of up to 4A without excessive heat generation. The device boasts a high voltage regulation accuracy of ±0.75% using standard 1% resistors, ensuring precise battery management.

 

With an input voltage capability of up to 24V and a maximum battery voltage of 18V, the MAX745EAP is suitable for a range of applications including desktop cradle chargers, cellular phones, notebook computers, and hand-held instruments. Its 300kHz PWM operation allows for low-noise performance and the use of small external components. The IC operates as a stand-alone unit, requiring no microcontroller for basic charging functions.

 

Packaged in a 20-SSOP surface-mount configuration, the MAX745EAP operates within an ambient temperature range of -40°C to 85°C. Its high efficiency of 90% contributes to power savings and thermal management in battery charging systems.
