Description

TIDA-00589 demonstrates the fully-integrated single-cell 5A charger bq25895 with 3.1A synchronous boost operation. bq25895 is a single-chip 1S power bank solution supporting high voltage adaptor to achieve up to 5A fast charging. The high efficiency of the synchronous boost maximizes the power bank operation time. bq25895 is  pin-to-pin compatible to the bq24195 and bq24195L power bank chargers.

Features
  • Support high voltage adaptor to achieve up to 5A charging current
  • Adjustable-voltage high-efficiency 3.1A synchronous boost operation
  • Input Current Optimizer (ICO) to best utilize the adaptor
  • ADC to provide system and battery monitoring
  • Both host control and autonomous charging when the host is not available
  • Integrated low Rdson battery FET for long battery run time
