High Voltage 2 Amp Monolithic 2-Cell
Li-Ion Battery Charger
Description
The LT®3650 is a complete monolithic 2-cell Li-Ion/Polymer battery charger that operates over a 9V to 32V input voltage range (11.5V minimum start-up voltage). The LT3650 provides a constant-current/constant-voltage charge characteristic, with maximum charge current externally programmable up to 2A, set using an external current sense resistor. A precondition feature trickle-charges a low voltage battery, and bad-battery detection p...
