DESCRIPTION

Description

OVERVIEW

Product Overview

The TP4056 is a linear charging management IC for single-cell lithium-ion batteries, typically in an SOP-8 package. It integrates a power transistor to provide constant-current and constant-voltage charging control for a single lithium cell, along with charge status indication. It is suitable for portable electronics and small energy storage devices that require single-cell lithium battery charging, simplifying charger circuit design and integration into space-constrained terminals. Specific charge current, voltage accuracy, and protection features should be confirmed with the original manufacturer's datasheet.

APPLICATIONS

Applications

  • Battery charging management for small electronic devices such as portable Bluetooth earphones and smart bands.
  • Charging control for single-cell lithium battery products such as power banks.
  • Charging circuits for built-in lithium batteries in small toys and e-cigarettes.
FEATURES AND BENEFITS
