The CXPR7899 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 (V_OVP =7.1V). 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. The IC also monitors its die temperature and switches off if it exceeds 145℃. When the IC is controlled by a processor, the IC provides status information about fault conditions to the host.

The CXPR7899 is available in Green TDFN-2×2-8L package and is rated over the -40℃ to +85℃ temperature range.4WE嘉泰姆
