General Description

The SY6974 is a fully-integrated switching battery charger with system power path management devices for single cell Li-ion and Li-polymer battery in a wide range of tablet and other portable devices.

Its low impedance power path optimizes switching conversion efficiency, reduces battery charging time and extends battery life during the discharging mode.

The I2C serial interface with charging and system settings makes the device a truly flexible solution.

Key Features

  • for battery charging and system operation, including negative thermistor monitoring, charging safety timer and over-voltage / over-current protections. The thermal regulation will reduce charge current when the junction temperature exceeds 110°C (programmable). The STAT output reports the charging status and any fault conditions. The /PG output in the SY6974 indicates if a good power source is present. The INT immediately will notify the host when a fault occurs. The SY6974 are available in QFN4.
