Product Introduction
The TP4056H-TD series is a linear lithium battery charger IC with a maximum input voltage tolerance of 33V and a maximum charge current of 1.2A, employing trickle, constant current, and constant voltage charging modes. The charge voltage can be set to 4.2V or 4.35V, and the charge current is configurable via an external resistor. When the battery voltage reaches 4.2V or 4.35V and the charge current drops to C/5 or C/10 of the programmed value, the IC terminates charging and enters standby mode. Upon removal of the power supply, the IC automatically enters a low-power standby state. Suitable for USB and adapter power sources, the IC features an internal PMOSFET architecture with integrated reverse-charge protection, eliminating the need for external sense resistors and isolation diodes.
