The ML5245 is a protection IC for 5- to13-cell Li-ion rechargeable battery pack. It detects individual cell
overvoltage/undervoltage and pack overcurrent/over-temperature, and then automatically turns on or turns off
the external charge/discharge NMOS-FETs accordingly.
Also, the ML5245 has a cell voltage monitor function so that the individual cell voltage can be monitored by
an external microcontroller.
