PT6112 Standalone Linear Li-Ion Battery Charger with Thermal Regulation GENERAL DESCRIPTION The PT6112 is a highly integrated Li-ion battery linear charging management device targeted at space limited portable applications. The PT6112 offers an integrated MOSFET and current sensor, reverse blocking protection, high accuracy current and voltage regulation, charge status indication, and charge termination in a SOT23 or ESOP8 package. The PT6112 has low external component count. The PT6112 charges a battery in three phases: trickle charging, constant current, and constant voltage. No external sense resistor is needed, and no blocking diode is required due to the internal MOSFET architecture.
