MC32BC3770
features single input with a 20 V withstanding input and charges the battery with the current up to 2.0 A. The charging parameters and operating modes are fully programmable over an I2C Interface that operates up to 400 k Hz.
The BC3770 is a highly integrated synchronous switch-mode charger, featuring integrated OVP and Power FETs. The charger and boost regulator circuits switch at 1.5 MHz to minimize the size of external passive ponents. The BC3770 is able to operate as a boost regulator for USB-OTG function via either I2C mand or an external pin from the host/processor. The BC3770 is available in a 25-bump, 2.27 mm x 2.17 mm, WLCSP package.
