The MAX745EAP+T from Analog Devices (formerly Maxim Integrated) is a versatile switch-mode battery charger designed for lithium-ion (Li+) battery packs. It efficiently charges 1 to 4 Li+ cells, delivering a regulated charging current of up to 4A without excessive heat generation. The device boasts a high voltage regulation accuracy of ±0.75% at the battery terminals, utilizing low-cost 1% resistors for setting the output voltage.
This IC operates with up to a 24V input and a maximum battery voltage of 18V. It features 300kHz PWM operation for low-noise and small component size. The MAX745EAP+T is designed for stand-alone operation, eliminating the need for a microcontroller. Its applications include Li+ battery packs, desktop cradle chargers, cellular phones, notebook computers, and hand-held instruments.
The device is available in a 20-SSOP surface-mount package. It operates within a temperature range of -40°C to 85°C (TA).
