SY20716D1 Highly Integrated USB Compliant Single Li-Ion Cell Switching Charger with USB-OTG Function General Description The SY20716 is a highly efficient, buck-mode switching charger designed for single-cell Li-ion and Li-polymer batteries. This device enables a comprehensive solution for portable devices by integrating essential components such as the blocking MOSFET, power MOSFETs, input current sensing circuits, and the charger controller. It is fully USB compliant, ensuring minimized charging times when powered via a USB port. Additionally, the SY20716 supports USB on-the-go (OTG) functionality through its built-in boost regulator. The device employs three internal digital-toanalog converters (DACs) to set and regulate the battery voltage, battery charging current, and adapter input current limit. These parameters are programmable via I2C by the host controller. The SY20716 features an adaptive input current limit, which optimizes the charging current to reduce charging time while preventing overloading of the input source. The SY20716 is available in a compact CSP 1.93mm x 2.05mm – 20 pin package. Applications Features  Up to 18V Absolute Maximum Input Voltage  6V Maximum Operating Input Voltage  Up to 1.25A Charge Current (68mΩ RSEN)  Up to 1.55A Charge Current (55mΩ RSEN)  Adaptive Input Current Limit  ±5% Input Current Limit Accuracy at 500mA  ±0.5% Charge Voltage Accuracy  I2C Controls (Up to 3.4Mbps):  Battery Charge Voltage (3.5V – 4.44V)  Battery Charge Current (550mA – 1.25A)  Termination Current (50mA – 400mA)  Battery Weak Voltage (3.4V – 3.7V)  Input Current Limit  VBUS Threshold for Adaptive Input Current  Low Charge Current Mode Enable And Disable  Termination Enable and Disable  Integrated Loop Compensation  Internal Soft-Start  PADs  Bad Adapter Detection and Rejection  Smartphones  Portable Equipment with Rechargeable Batteries  Battery Back-Up Systems  3MHz Switching Frequency  Automatic High Impedance Mode for Reduced Power Consumption  5V,1A Boost Mode for USB OTG  Spread Spectrum Control for Improved EMI Performance  Factory Test Mode for GSM Calibration Without a Battery  CSP1.93x2.05-20 Package DS_SY20716D1 Rev.1.0 © 2018 Silergy Corp.
