 PT6113 _ DS Rev EN_ 1. 0 PT611 3 GENERAL DESCRIPTION The PT6113 is a highly integrated Li - ion battery linear charging management device targeted at space limited portable applications. The PT6113 offers an integrated MOSFET and current sensor, reverse blocking protection, high accuracy cu rrent and voltage regulation, charge status indicat ion, and charge termination in ESOP8 package. The PT6113 charges a battery in three phases: trickle charging, constant current and constant voltage. N o blocking diode is required due to the internal MOSFE T architecture. The thermal feedback regulates the charging current to limit the chip temperature during high power operation or high ambient temperature to maximize the charge rate without risk of overheating . The charge voltage is fixed at 4.35 V, and the charge current can be programmed externally with a single resistor. The PT6113 automatically terminates the charge cycle when the charge current drops to 1/10 the programmed value after the final float voltage is reached.
