About:

TP4056 is available from TOP POWER in China, which is very popular in Li-Ion charger.

Although both TP4056 and LTC4056 are Li-Ion charger controllers, they are totally different in pins, package, and perforamance. Let us look it in this way, TP4056 is low cost, market proven IC with more features, it lacks of technical support for world wide makers/clients.

It has no English datasheet. Therefore I translate its Chinese version to English. Today I found its preliminary datasheet in English from TOP POWER, however it lacks of many application information which is available in Chinese version. I decided to complete my translation anyway. Up to now, it is not finished yet, but here is its draft version.

We resell off-the-shelf TP4056 based charger breakout boards from China. Additionally, we offer modified breakout boards and accessories with:

• TP4056 Li-Ion charger breakout with protection circuit for 18650 Li-Ion batteries
• TP4056 Li-Ion charger breakout with step-up DC/DC to 5V
• Converter kit including all kinds of connectors, DC plug, screw terminal, USB micro/mini connector, as well as JST cable, T connector and Tamiya connector

Features:

• Up to 1000mA programmable charge current
• No external MOSFET, sense resistor or blocking diode required
• Complete linear charger in SOP package for single cell Lithium-Ion battery charger
• Constant-current/constant-voltage operation with terminal regulation to maximize charge without risk of overheating
• Preset 4.2V charge voltage with 1.5% accuracy
• Charge Current Monitor Output for Gas Gauging
• Automatic recharge
• Dual status output of charging, no battery and fault state
• C/10 charge termination
• 55uA max supply current in shutdown mode
• 2.9V trickle charge threshold
• soft-start limits inrush current
• Battery temperature sense
• Available in a 8-lead SOP-PP/MSP-PP package

Applications:

• Mobile phone, PDA
• MP3/MP4 player
• Digital cameras
• E-dictionary
