LAPIS ML5245
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.| Part No. | ML5245 |
