SGM4064 Over-Voltage Protection IC and Li+ Charger Front-End Protection IC with LDO Mode GENERAL DESCRIPTION The SGM4064 is a charger front-end integrated circuit designed to provide protection to Li-Ion batteries from failures of the charging circuitry. The IC continuously monitors the input voltage and the battery voltage. The device operates like a linear regulator, maintaining a 5.1V output with input voltages up to the input over-voltage threshold (VOVP = 6.8V). During input over-voltage conditions, the IC immediately turns off the internal pass FET disconnecting the charging circuitry from the damaging input source. Additionally, if the battery voltage rises to unsafe levels while charging, power is removed from the system.
