NanJing Top Power TP4056 Datasheet
The TP4056 linear charger is designed for single‑cell Li‑ion or Li‑polymer batteries. It is supplied in SOP‑8/MSOP‑8 packages with a bottom heat‑sink and is suitable for portable devices such as phones, MP3 players, cameras and USB chargers.
Key features include constant‑current/constant‑voltage operation, programmable charge current via the PROG pin, battery‑temperature detection, under‑voltage lockout, automatic re‑charge, dual LED status indicators and a low‑power standby mode of 55 µA. The device also provides internal thermal feedback to limit current when the junction temperature approaches 145 °C. This manual is written in Chinese.

Questions answered in Nanjing拓微集成电路 manuals
How is the charge current programmed on the TP4056?
The charge current is set by connecting an external resistor between the PROG pin and ground; the resistor value determines the current according to the formula given in the datasheet.
What is the standby current after charging is complete?
The device enters a low‑power standby mode drawing about 55 µA.
