MOTF4055-A6
MOTF4055-A6 is a high-voltage linear charging management IC manufactured by Guangdong Inmark Electronics Co., Ltd. It is known for its high precision, high quality and high reliability. It is suitable for charging voltage detection, current control and other management functions on single-cell lithium battery products such as Bluetooth headsets, electronic cigarettes, toys, etc.
Product Overview
MOTF4055-A6 is an excellent single-cell lithium-ion battery constant current/constant voltage linear charging IC. It can be powered by USB power or adapter power. It has built-in power MOSFET, detection resistor and isolation diode. It has thermal regulation function, which can maximize the charging rate without the risk of overheating. The charging cut-off voltage is 4.2V, and the charging current can be set by an external resistor. When the charging current drops to 1/10 of the set value, the chip will automatically terminate the charging cycle. In addition, there are battery temperature monitoring, undervoltage lockout, automatic recharging and other functions.
