LAPIS ML5233
The ML5233 is a protection IC for the 4- to 10-cell Li-ion rechargeable battery pack. It detects individual cell overvoltage/undervoltage and the pack overcurrent/over-temperature, and then automatically turns on or turns off the external charge/discharge NMOS-FETs accordingly. Also the ML5233 can be cascaded to handle battery packs with more than 10 cells.| Part No. | ML5233 |
