Introduction

AI Translation

SY6918 is a 5V adapter input with up to 18V surge bidirectional regulator designed for single cell Li-Ion battery power bank application. Advanced bidirectional energy flow control with automatic input power source detection is adopted to achieve battery charging mode and battery power supply mode alternately. SY6918 also integrated the KEY control and LED status indication. SY6918 is available in QFN3x3 package to minimize the PCB layout size for wide portable applications.

SY6918 is a 4.5 - 5.35V VN up to 18V VIN surge bidirectional regulator designed for single cell Li-Ion battery power bank application. Advanced bidirectional energy flow control with automatic input power source detection is adopted to achieve battery charging mode and battery power supply mode alternately. If the external power supply is present, SY6918 runs in battery charging mode with fully protection function. If the external power supply is absent, SY6918 runs in battery power supply mode with output current capability up to 2.5A. SY6918 has integrated blocking switches to prevent current leaking from the system side or battery side to the input side. The high side switch protects the battery from high discharge current and short circuits at SYS point. SY6918 also provides the KEY control and LED status indication.
