This datasheet also covers the SY20743 variant, as both devices belong to the same single cell li-ion dc/dc switching charger family and are provided as variant models within a single manufacturer datasheet.
General Description
The SY20743/B/C is a fully-integrated switching battery charger with system power path management device for single cell Li-Ion and Li-polymer batteries in a wide range of tablets and other portable devices.
Key Features
are integrated: overvoltage and over-current protections, battery temperature
sensing, and charging safety timer. The device also integrates a thermal regulation loop, and thermal shutdown comparator to prevent overheating. The charging status and fault conditions are reported in the CHRG_STAT register, and the INT output will trigger to notify the host when any fault occurs. The input source status is reported using the PG_STAT register and the /PG output (SY20743/C). The SY20743/B/C is availa.

ection and OTG, JEITA Compliant, Power Path Management General Description The SY20743/B/C is a fully-integrated switching battery charger with system power path management device for single cell Li-Ion and Li-polymer batteries in a wide range of tablets and other portable devices. The low on-resistance of the main switch, synchronous rectifier switches and BATFET helps improving the switching conversion efficiency, shortening the charge cycle, and prolonging the battery life. The integrated I2C serial interface enables the host to configure the device for different applications.
