MOJAY-M4054 Product Overview

MOJAY-M4054 Product Overview: M4054 is a complete single-cell lithium battery constant current and constant voltage linear charging IC. It is available in a tiny SOT-23-5L package and requires only a few external components to make it fully suitable for portable applications. The M4054 is designed for USB power features, and the M4054 can also be used as a stand-alone linear lithium battery charger. ·Charging current can be programmed up to 800mA. No need for external MOSFET, diode and sense resistor. Over-temperature protection constant current and constant voltage charging · Can charge single-cell lithium battery directly from USB port · Preset 4.2V charging voltage, accuracy up to ±1%·Trickle charge compartment 2.9V·Can be set without trickle charge mode ·Soft start, effectively limit the inrush current ·RoHS SOT-23-5L package
