MOTF690-ES
MOTF690-ES is a high-voltage boost type 2-cell lithium battery 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 2-cell lithium battery products such as smart door lock battery boxes, 2.4G remote control cars, fascia guns, etc.
Product Overview
MOTF690-ES is an excellent high-voltage boost type constant current/constant voltage linear charging IC for 2-cell lithium-ion batteries. It can be powered by USB power or adapter power 5V. 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 8.4V, 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 functions such as battery temperature monitoring, undervoltage lockout, and automatic recharging.
