Overview LTH7R. is a constant current/constant voltage charger chip, mainly used for charging single-cell lithium batteries. No external detection resistor is required, and its internal structure is MOSFET, so no external reverse diode is required. LTH7R. can automatically adjust the charging current to limit the chip t.

LTH7R Features

* and has an indication pin to indicate the charging termination status and input voltage status. Second, characteristics ÿ Programmable charge current up to 500mAÿ No external MOSFET, sense resistor, or reverse diode requiredÿ Constant current/constant voltage mode operation with thermal protection
