This paper describes the design of a high input voltage,dual section series connection,linear charging management chip.High precision charging current can be achieved by detecting resistance through external current.It has a thermal feedback circuit inside,which can control the temperature of the chip during the charging process.The test results show that the chip has complete protection functions for overvoltage,overcurrent,and short circuit.
