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. Charger: Adaptive charging current control, excellent adapter compatibility Support 4.20/4.30/4.35/4.40V batteries State of Charge (SOC) indicator: Integrated LED controller supports 4/3/2/1 LEDs as the SOC indicator Fully featured: Key ON/OFF Integrated flashlight controller Integrated cellphone plug-in and plug-out detector Low power: Smart load detector, switching to standby mode automatically <100 µA standby current Ultra simplified BOM Integrated power FET, charging/boosting with a single inductor Features/Specs: 1A Synchronous switching charger and 5V Boost converter efficiency u
