we are searching for a 2-Cell LiIon Battery Management System.
The BMS should be part of a handheld, battery powered Test&Measurement device.
As such it is required that there is a undervoltage protection/shut-down to prevent the battery cells from beeing depleted fully.
We came across the MP2672A which seems to have all functionality apart from a battery protection as the batteries seem to remain connected to the load via Q3 till a 5V supply voltage is connected to Vin again and recharges.
How can we protect the batteries from beeing depleted fully?
Are there other BMS devices from MPS that monitor and protect the batteries, or do we have to design a dedicated protection circuit, that cuts the connection to the BMS/load?
thanks in advance
