Tariff Charges
The Freescale BC3770 is a fully programmable switching charger with dual-path output for single-cell Li-Ion and Li-Polymer battery. The dual-path output allows mobile applications with a fully discharged battery to boot up the system. High efficiency and switch-mode operation reduces heat dissipation and allows for higher current capability for a given package size Single input with a 20V withstanding input and charges the battery with an input current up to 2A Charging parameters and operating modes are fully programmable over an I2C Interface that operates up to 400 kHz Highly integrated featuring OVP and Power FETs Supports 1.5 MHz switching capabilities
