Product Description

The MP2670 is a high performance single cell Li-Ion/Li-Polymer battery charger protection circuit. By integrating high voltage input protection into the charger IC, the MP2670 can tolerate an input surge up to +30V. The device features input over voltage protection (OVP), battery over voltage protection (BOVP) and over charge current protection (OCP). The device also provides fault indications to the system when any of the protection events happens. For guaranteed safe operation, the MP2670 monitors its own internal temperature and turns off the MOSFET bridging VIN and OUT when the die temperature exceeds 150oC. The MP2670 is available in a 10-pin 3mm x 3mm QFN package.

Battery Charger Protection Circuit Evaluation Board

The EV2670DQ-00A is an evaluation board for the MP2670. EV2670DQ-00A includes mainly two parts: MP2670 protection circuit and MP2602 charging system. The output of MP2670 is the input of MP2602.

By integrating high voltage input protection into the charger IC, the MP2670 can tolerate an input surge up to 30V.

The MP2670 features input over voltage protection (OVP), battery voltage over voltage protection (BOVP), and over charge current protection (OCP). Additionally, MP2670 also monitors its own internal temperature and provides thermal protection (OTP). The device also provides fault indication. Any protection event can be indicated by customer.
