LT3650EMSE-4.2#PBF

The LT3650EMSE-4.2#PBF is a High Voltage 2A Monolithic 2-cell Li-ion Battery Charger operates over a 4.75 to 32V input voltage range (7.5V 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 provides a signal and suspends charging if a battery does not respond to preconditioning. It can be configured 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 (85µA) standby mode. An auto-restart feature starts a new charging cycle if the battery voltage drops 2.5% from the float voltage or if a new battery is inserted into a charging system. The LT3650 contains an user-programmable internal safety timer.
