Introduction

AI Translation

ME4055-N is a single-cell lithium-ion battery constant-voltage/constant-current charge management IC with a 9V voltage rating and a maximum charge current of 800mA. Since linear chargers generate significant heat under large input-to-output voltage differentials, an internal thermal feedback circuit is incorporated to regulate the chip temperature during charging by reducing the charge current to a lower level, accommodating the system's thermal dissipation requirements. The SOT23-6 package with minimal external components makes it an ideal choice for portable applications. ME4055-N requires no current sense resistor and no external blocking diode for reverse-current protection. The charge termination voltage is fixed at 4.2V/4.34V, and the charge current is adjustable via an external resistor. When the charge current drops to 1/10 of the constant-current value, ME4055-N terminates charging. When the input voltage (adapter or USB) is removed, ME4055-N enters sleep mode. The internal charge path is automatically disabled and the input voltage drops. In this state, the battery leakage current is reduced to below 2µA. When ME4055-N is powered but the battery is removed, the chip current drops to 55µA to minimize system power consumption.
