TEXAS INSTRUMENTS BQ24295RGET 芯片, 电池充电, 锂离子/锂聚合物, VQFN-24
The is a single cell USB Charger with adjustable voltage. Its low impedance power path optimizes switch-mode operation efficiency, reduces battery charging time and extends battery life during discharging phase. The I2C serial interface with charging and system settings makes the device a truly flexible solution. The device supports 3.9 to 6.2V USB input sources, including standard USB host port and USB charging port with 6.4V over-voltage protection. The BQ24295 is compliant with USB 2.0 and USB 3.0 power specifications with input current and voltage regulation. To set the default input current limit, the bq24295 detects the input source through D+/D- detection following the USB battery charging spec 1.2. In addition, it detects non-standard 2A/1A adapters. The power path management regulates the system slightly above battery voltage but does not drop below 3.5V minimum system voltage programmable.
Device has limited built-in ESD protection, leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
