DESCRIPTION

The bq24150/1 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

•

20-V Absolute Maximum Input Voltage Rating

6-V Maximum Operating Input Voltage

Built-In Input Current Sensing and Limiting

I²C interface. The bq24150/1 integrates

Integrated Power FETs for Up To 1.25-A

Charge Rate

synchronous PWM controller, power MOSFETs, input

current sensing, high-accuracy current and voltage

regulation, and charge termination, into a small

WCSP package.

•

Programmable Charge Parameters through

I²C™ Interface (up to 3.4 Mbps):

–

Input Current

The bq24150/1 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, bq24150/1

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.
