资 源 简 介
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.
