TP4333 Fully-Integrated Power Bank System-On-Chip Charger IC
Description
TP4333 Fully-Integrated Power Bank System-On-Chip Charger IC – Package-SOP8
TP4333 is a synchronous step-up single chip solution designed for mobile power supply. It integrates a linear charge management module, a synchronous discharge management module, a power detection and LED indication module, and a protection module. The TP4333 has a built-in charge and discharge power MOS. The charge current is fixed at 0.8A. Synchronous boost supports 1A output current. The TP4333 integrates multiple safety protection functions such as temperature compensation, over-temperature protection, over-charge and over-discharge protection, output over-voltage protection, output overload protection, and output short-circuit protection to ensure the safety of the chip and lithium-ion battery. The application circuit is simple. Only a few components are needed to achieve charge management and discharge management.
