SOUTHCHIP/南芯 SC89601DQDLR QFN4X4-24 带NVDC电源路径管理的单节锂离子电池高效同步3A降压充电器

DESCRIPTION
The SC89601DQDLR is a 1.5MHz highly integrated switch-mode buck charger for 1 cell Li-ion battery applications and NVDC system power path management, which separate the system load and charge current, also the system can power up with deep depletion battery. System can get the power from VBUS, VBAT or both. It supports 3.9-13.5V input voltage, up to 3A charging current and provide battery charge management functions including trickle charge, constant current charge, constant voltage charge, charge termination, auto recharge and charging status indication.
The SC89601DQDLR supports flexible charge current option, the user can program the current and all others charger spec by I2C. With the charger management function, the IC can be used to charge 1 cell Li-ion battery.
The SC89601D supports USB OTG with up to 1.2A output with PFM/PWM mode. Meanwhile, the SC89601D supports USB BC1.2 and non-standard adapters.
The SC89601D supports input current and voltage limit, input under voltage and over voltage protections, internal cycle by cycle current limit, battery short circuit protection, and output over voltage protection. It also offers charging safety timer and over temperature protection to ensure safety under different abnormal conditions.
The SC89601D integrated all MOSFETs, current sensing, loop compensation and I2C interface. The SC89601D is available in QFN(24)-4*4 package.
