The TP4067 is a complete single‑cell lithium‑ion battery charger that integrates battery‑ and input‑reverse‑polarity protection, programmable charging current, and thermal feedback. It operates from USB or an external adapter and is packaged in a 6‑lead SOT‑23‑6 package, making it suitable for portable applications.
Key features include 3 mA‑600 mA programmable charging current, VCC input range up to 8 V, standby current below 65 µA, and automatic termination at C/10. The device provides status pins (CHRG, STDBY) for charging indication and supports a wide temperature range for reliable operation in various environments. This manual is written in Chinese.
| Input voltage (VCC) range | 4.35 V – 8 V |
|---|---|
| Charging current range | 3 mA – 600 mA (programmable) |
| Standby current (no battery) | ≤ 65 µA |
| Maximum junction temperature | 150 °C |
The TP4067 supports a programmable charging current from 3 mA up to 600 mA.
Charging current is set by connecting a precision resistor between the PROG pin and ground; the resistor value determines the current.
The standby current is less than or equal to 65 µA.
