LTM8061 32V, 2A ÁModule Li-Ion/ Polymer Battery Charger FEATURES
The LTM«8061 is a high efficiency 32V, 2A Module« standalone Li-Ion battery charger. It is optimized for one and two-cell packs, with fixed float voltage options: 4.1V, 4.2V, 8.2V and 8.4V. The LTM8061 provides a constantcurrent/constant-voltage charge characteristic, with maximum charge current up to 2A. A precondition feature trickle charges a depleted battery, and bad battery detection provides a signal and suspends charging if a battery does not respond to preconditioning. The LTM8061 can be configured to terminate charging when charge current falls to one-tenth the programmed maximum current or to use an internal timer if a timebased termination scheme is desired. Once charging is terminated, the LTM8061 enters a low current standby mode. An auto-restart feature starts a new charge cycle if the battery voltage drops 2.5% from the float voltage, or if a new battery is inserted into a charging system.
