LP28057 charge equivalent, 1.2a single-chip li-ion charge.
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 Info.
No external sense resistor is needed, and no blocking diode is required due to the internal MOSFET architecture. Therma.
The LP28057 is a complete constant-current/ constant- voltage linear charger for single cell lithium-ion batteries. Its ESOP-8 package and low external component count make the LP28057 ideally suited for portable applications. No external sense resis.
