LTH7R. 0.5A Linear Lithium lon Battery Charger IC SOT23-5


Technical Datasheet


LTH7R. is a constant current/constant voltage stand charger chip, mainly used for single-cell lithium battery charging. There is no need to connect an external detection resistor, and its interior is a MOSFET structure, so there is no need to connect an external reverse diode.

LTH7R. Under high power and high ambient temperature, it can automatically adjust the charging current to limit the chip temperature. Its charging voltage is fixed at 4.2V, and the charging current can be adjusted through an external resistor. When the float voltage is reached and the charging current drops to 1/10 of the setting circuit, LTH7R. automatically terminates the charging process. When the input voltage is removed, the LTH7R. automatically enters low current mode, drawing less than 2uA from the battery. When LTH7R. enters standby mode, the supply current is less than 25uA.

LTH7R. can also monitor the charging current, has the characteristics of voltage detection, automatic cycle charging, and has an indicator pin to indicate the charging termination status and input voltage status.
