TP4056 SMD IC ESOP-8 4056 TP4056

Product Overview:

The TP4056 is a complete constant-current/constant-voltage linear charger for single-cell lithium-ion batteries. It is housed in an SOP8 package with a thermal pad at the bottom to facilitate heat dissipation, making it highly suitable for portable device applications. The chip is designed to work with both USB power and adapter power sources.

Core Specifications:

• Manufacturer: TPOWER Semiconductor

• Package Type: SOP8 (with thermal base)

• Function: 1A Lithium-Ion Battery Charger

• Charging Voltage: 4.2V (±1% accuracy)

• Maximum Charging Current: 1A (set via external resistor)

Features:

• Smart Thermal Regulation: Automatically adjusts the charging current to maximize charging rates while keeping the chip temperature within safe limits under high-power or high-ambient-temperature conditions.

• Protection: Includes an internal anti-reverse charging circuit, eliminating the need for external blocking diodes.

• Efficiency: Features a smart recharging function and automatic charge termination when the current drops to 1/10th of the programmed value (C/10 termination).

• Power Modes: Enters an ultra-low-power standby mode (less than 1µA) when the input power is removed. It also offers a shutdown mode that reduces operating current to 40µA.

• Monitoring: Provides independent control signals for charge status and charge termination indicators.

Applications:

• Portable Electronics: Ideal for cellular phones, handheld devices, and other portable equipment.

• Battery-Powered Modules: Suitable for systems requiring integrated, safe, and efficient battery management.

• USB-Powered Gadgets: Designed to operate reliably within the power specifications of USB interfaces and standard power adapters.
