Product Overview:The LP4056H is a complete constant-current/constant-voltage linear charger for single-cell lithium-ion batteries. Designed for portable applications, it integrates power components and sensing circuitry into a small package to simplify battery management in compact electronics.

Core Specifications

  • Manufacturer: LowPower Semi

  • Package Type: ESOP-8 (with thermal pad)

  • Function: Standalone Linear Li-Ion Battery Charger

  • Input Voltage Range: 4.2V to 6.5V

  • Control Interface: Programmable via external resistor (Charge Current)

Features

  • Charging Precision: Delivers high-accuracy constant-current/constant-voltage charging with a preset 4.2V float voltage.

  • Thermal Regulation: Includes on-chip thermal feedback that automatically adjusts the charge current to limit die temperature during high-power operation or high ambient temperature conditions.

  • Safety Monitoring: Features automatic recharge, battery temperature monitoring (NTC interface), and protection against charge over-voltage.

  • Status Indication: Provides dual open-drain outputs for Charge Status (CHRG) and End-of-Charge (STDBY) indication.

  • Low Idle Current: Consumes minimal current in standby mode, extending system battery life.

Applications

  • Portable Electronics: Ideal for charging single-cell Li-Ion batteries in handheld devices, Bluetooth speakers, and wearable technology.

  • Consumer Appliances: Used in localized battery-powered modules where a standard 5V USB power rail is available.

  • Embedded Systems: Serves as a reliable, small-footprint solution for adding rechargeable battery functionality to PCB designs intended for JLCPCB assembly.
