High Voltage 2 Amp Monolithic 2-Cell Li-Ion Battery Charger

The LT3650 is a complete monolithic two-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-volt- age 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 provides a signal and suspends charging if a battery does not respond to preconditioning. The LT3650 CAN be con gured to terminate charging when charge current falls to C/10, or one-tenth the programmed maximum current. Once charging is terminated, the LT3650 enters a low current (85A) standby mode. An auto-restart feature starts a new charging cycle if the battery voltage drops 2.5% from the oat voltage, or if a new battery is inserted into a charging system. The LT3650 contains a user-programmable internal safety Timer (typically set to a three-hour full cycle time). The IC CAN be con gured to use this internal Timer if a time-based termination scheme is desired in which charging CAN con- tinue below C/10 until a desired time is reached. The LT3650 is available in a low pro le (0.75mm) 3mm 3mm 12-pin DFN package. By Linear Technology Corporation
