LC05111C18MTTTG Description

Short technical summary and product information.

The LC05111C18MTTTG from On Semiconductor is an integrated circuit designed for the protection of 1-cell Lithium-Ion secondary batteries. It features built-in charge and discharge power MOSFETs with a typical ON resistance of 11.2 mΩ. The device incorporates highly accurate detection circuits for over-charging, over-discharging, and over-current conditions, with specific detection voltages for over-charge at 4.0 V to 4.5 V and over-discharge at 2.2 V to 2.7 V.

 

This IC offers fixed internal delay times for detection and release. It supports 0 V battery charging and includes an auto wake-up function. The discharge over-current detection ranges from 2.0 A to 8.0 A, while charge over-current detection ranges from -8.0 A to -2.0 A. The operating temperature range is -40°C to +85°C.

 

The LC05111C18MTTTG is supplied in a 6-WDFN (4x2.6) package, suitable for surface mounting. Its compact size and integrated functionality make it ideal for battery protection systems requiring minimal external components.
