The LP3946 is a stand-alone single cell Li-Ion charger with an integrated pass transistor and current sense resistor. In addition to its charging function, it can be used in low dropout (LDO) mode.

The algorithm for this circuit is that the blocking MOSFET must be disabled if the battery voltage exceeds the battery charger output voltage. In this circuit MN1 is connected in the low side of the ...

A DC-to-DC charger uses excess engine-alternator current, typically redirected from the starting battery bank, to charge the house battery bank. This can also be performed by an automatic charging ...
