Product Introduction
The TP4056 is a complete constant-current/constant-voltage linear charger for single cell lithium-ion batteries. It’s ESOP8/EMSOP8 package and low external component count make the TP4056 ideally suited for portable applications. The TP4056 is designed to work within USB power specifications (wall adaptor or USB supply).
No external sense resistor or blocking diode is required due to it’s internal PMOSFET architecture and integrated reverse discharge protection. TP4056 limits the charge current based on die temperature during high power operation or high ambient temperature. The charge voltage is fixed at 4.2V, and the charge current can be programmed externally with a resistor. TP4056 automatically terminates the charge cycle when the charge current drops to 1/10th of the programmed value after reaching the final float voltage.
When input power supply is removed, TP4056 will enter a low current state with battery drain current less than 2uA. TP4056 can also enter a shut-down mode with power supply, lowering supply current to less than 55uA.
Other features include cell temperature monitor, under voltage lockout, automatic recharge and two LED status indication pins for charge termination and presence of an input voltage.

Frequently Asked Questions
What are the primary charging specifications of the TOP POWER ASIC TP4056-42-ESOP8?
The TOP POWER ASIC TP4056-42-ESOP8 is a standalone linear battery charger designed for a single lithium-ion or lithium-polymer cell. The device operates from an input voltage range of 4V to 8V and uses a constant-current/constant-voltage (CC/CV) charging algorithm. It provides a fixed 4.2V charge voltage, and the charge current is programmed with a single external resistor and can be configured up to 1A.
Which batteries and power sources are compatible with the TP4056-42-ESOP8?
The TP4056-42-ESOP8 is designed for charging a single lithium-ion or lithium-polymer battery. It is designed to operate from a USB power source or a wall adapter, making it suitable for single-cell battery charging applications. The device provides a fixed 4.2V charge voltage and supports programmable charging current up to 1A using an external resistor.
What protection and charging-management features are built into the TP4056-42-ESOP8?
The TP4056-42-ESOP8 automatically progresses through trickle-charge, constant-current, and constant-voltage charging stages based on battery condition. Charging terminates automatically when the charge current drops to one-tenth of the programmed value after reaching the final charge voltage. The device also supports automatic recharge when the battery voltage falls below the recharge threshold. Additional features include thermal regulation, under-voltage lockout (UVLO), cell temperature monitoring through the TEMP pin, C/10 charge termination, soft-start, and two charge-status output pins (CHRG and STDBY).
