STMicroelectronics Battery Charger for STBC02

STEVAL-ISB041V1 Li-Ion/Li-Po Battery Charger Evaluation Board

The STEVAL-ISB041V1 board is based on an STBC02 battery power management chip, integrating a linear charger for single-cell Li-Ion batteries with protection functions, an LDO regulator, two SPDT load switches and intelligent reset logic. It will charge single-cell Li-Ion/Li-Po batteries with a CC-CV algorithm and charge termination. The STEVAL-ISB041V1 can work in stand-alone mode and the STBC02 controlled via a single-wire interface.

• Fast-charge current up to 450mA
• Pre-charge current from 1mA to 450mA
• Adjustable floating voltage up to 4.45V
• On-chip always-on low quiescent current LDO regulator
• On-chip 2 x 3Ω SPDT load switches
• Reset generator triggered by USB detection
• Automatic power path management
• Auto-recharge function
• Battery over-charge, over-discharge and overcurrent protection
• Charging timeout to terminate the charging process for safety reasons
• Shipping mode allows low battery leakage when over-discharged
• Very low battery leakage in over-discharge and shutdown mode
• Charge/fault status output
• Battery voltage pin allows external gauging
• SWIRE interface allows the STBC02 functions to be controlled externally
• Powered from micro-AB USB connector
