General Description

The LP28021/A is a plete constant-current/ constant voltage linear charger for single cell lithium-ion batteries.

Its TDFN-10 package and low external ponent count make the LP28021/A ideally suited for portable applications.

No external sense resistor is needed, and no blocking diode is required due to the internal MOSFET architecture.

Key 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 LP28021.
  • BAT Voltage Default: 4.2V 43: 4.35V F: Pb-Free Package Type QV: TDFN-10 SP: ESOP8 Function Class Default：OCP Adjustable A：Enable Features.
  • Very Low Power Dissipation.
  • Input Voltage: 3.8V~36V.
  • Input OVP: 6.1V.
  • Protection of Reverse Conn.
