LP28057 Description
Preliminary Datasheet LP28057 1.2A Single-chip Li-ion Charge with Protection of Reverse Connection of Battery General .
The LP28057 is a complete constant-current/ constant- voltage linear charger for single cell lithium-ion batteries.
LP28057 Features
* include charge current monitor, under voltage lockout, automatic recharge and a status pin to indicate charge termination and the presence of an input voltage. Order Information
LP28057
* F: Pb-Free
Package Type SP: ESOP-8
Features
* Protection of Reverse Connection
LP28057 Applications
* No external sense resistor is needed, and no blocking diode is required due to the internal MOSFET architecture. Thermal feedback regulates the charge current to limit the die temperature during high power operation or high ambient temperature. The charge voltage is fixed at 4.2V, and the charge cu
