Shenzhen Fu Man Electronics Co., Ltd. SHENZHEN FUMAN ELECTRONICS CO., LTD. FM9833 (File No: S & CIC1296 ) Mobile Power Management Private IC Outline FM9833 A mobile power source is designed specifically for a single chip integrates all the charging, discharging, protection, led Automatic load identification in one of the portable power management IC . FM9833 With a chip, with no external MOSFET , DW01 , Schottky devices, etc., to solve the basic needs of mobile power. Due to saving and Schottky MOSFET Energy loss, the energy conversion efficiency of the system 92 %the above. And with minimal peripheral greatly reduce production costs and improve production efficiency. FM9833 Integrated internal over-temperature protection, anti-intrusion protection when charging, short circuit protection, short circuit proof lock, soft start protection, lithium battery overcharge and over discharge almost all of the security features protection, undervoltage protection to ensure the security chip and lithium batteries. Feature Ø Synchronous boost, no external MOSFET Schottky Ø 5V / 1A Synchronous boost the efficiency of 90% Ø Automatic recognition load, standby current 20UA the following Ø Load short prompts, automatic recovery after the short clearing Ø Integrated over-voltage protection, over temperature protection, short circuit protection, overload protection Ø maximum 600mA Linear charging current constant charging current value may be externally programmed Ø Having a charge, full discharge, low power LED indicates Ø Lithium battery overcharge, over discharge, and short circuit protection Ø Trickle / CC / CV charging threeØ Charge cutoff voltage: 4.20V / 4.35V Ø Package: SOP-8 application Ø mobile power; Ø IPAD Standby power and other digital devices.
