The MP2678 is a high performance single cell Li-Ion/Li-Polymer battery charger protection IC. By integrating the high voltage input protection, the MP2678 can tolerate an input surge up to +30V.?The device operates like a linear regulator, maintaining a 5V output with the input voltage up to the over voltage protection threshold.?MP2678 features input over voltage protection (OVP), battery over voltage protection (BOVP) and over charge current protection (OCP). When any fault condition happens, the IC will immediately turn off the internal N-MOSFET to disconnect the charging circuit from the input. The device also provides fault indications to the system when any of the protection events happens.?For guaranteed safe operation, the MP2678 monitors its own internal temperature and turns off the internal N-MOSFET bridging IN and OUT when the die temperature exceeds 140oC.? The MP2678 is available in an 8-pin 2x2mm QFN package.

The EV2678EG-104-00A is an evaluation board for MP2678EG-104, the high-performance protection IC for single cell Li+ battery charger maintaining a 5V output with the input voltage up to over voltage protection threshold 10.4V.
The device operates like a linear regulator, provides fault indication to the system when any protection events happens, including input over voltage protection (OVP), battery over voltage protection (BOVP), and over charge current protection (OCP). Additionally, it also monitors its own internal temperature and provides thermal protection (OTP).
EV2678EG-104-00A can also be used to evaluate other version MP2678EG with different input over voltage protection threshold with IC replacement.
