Description for the BQ24150A

The bq24150A/1A is a compact, flexible, high-efficiency, USB-friendly switch-mode charge management device for single-cell Li-ion and Li-polymer batteries used in a wide range of portable applications. The charge parameters can be programmed through an I²C interface. The bq24150A/1A integrates a synchronous PWM controller, power MOSFETs, input current sensing, high-accuracy current and voltage regulation, and charge termination, into a small WCSP package.

The bq24150A/1A charges the battery in three phases: conditioning, constant current and constant voltage. The input current is automatically limited to the value set by the host. Charge is terminated based on user-selectable minimum current level. A safety timer with reset control provides a safety backup for I²C interface. During normal operation, bq24150A/1A automatically restarts the charge cycle if the battery voltage falls below an internal threshold and automatically enters sleep mode or high impedance mode when the input supply is removed. The charge status is reported to the host using the I²C interface.

During the charging process, the bq24150A/1A monitors its junction temperature (T_J) and reduces the charge current once T_J increases to approximately 125°C. To support USB OTG device, bq24150A/1A provides VBUS (approximately 5.05 V) by boosting the battery voltage. The bq24150A/1A is available in 20-pin WCSP package.
