PI3USB9281XWEX is a battery management system (BMS) Power Management Integrated Circuit (PMIC) used to monitor and manage Li-ion and Li-Polymer battery systems. It can be used in a wide range of applications and products, including consumer electronics, automotive systems, power tools, telecommunications equipment and medical equipment. The PI3USB9281XWEX can be used to recharge and discharge the battery, monitor current and voltage levels, detect temperature and achieve balance throughout the battery pack.
The PI3USB9281XWEX has an integrated power management controller and safety features, with a small form factor of 3.2mmx2.6mm. The power management controller includes over-current protection, outputs short-circuit protection and current regulation for improved voltage accuracy. It also includes over-discharge protection, over-volt protection and thermal regulation to protect the battery system and enhance product life.
The PI3USB9281XWEX offers a variety of pins and modes, which can be used to connect to a wide range of product applications. The pins offer multiple I/O, PWM and ISRC programmable outputs and inputs. The power management controller can also be programmed with a simple command interface to choose the desired operating mode, input output characteristics and current limit values. As the power management controller provides fully configurable control, it can be used for a wide range of applications.
In addition to being a BMS PMIC, the PI3USB9281XWEX also offers a wide range of other features such as LED driver control, LED dimming control and LED strobing control. The LED driver control feature can be used to reduce LED current consumption and thus save energy. The LED dimming control feature can reduce current consumption while providing consistent light output over time. The LED strobing control feature enables higher light output efficiency and can be used in display applications such as backlighting.
The PI3USB9281XWEX is available in both SOIC-8 and WLCSP packages, and is designed to be used in either a single cell or in a multi-cell battery system. The WLCSP package provides the most flexibility, being used in space-constrained applications and applications that require high reliability. The PI3USB9281XWEX also provides an integrated low power shutdown feature to ensure low power consumption in standby mode. The remaining features include an ultra-low power wake-up timer, an emergency input pin, I2C interface and an embedded temperature sensor.
In summary, the PI3USB9281XWEX PMIC is a highly integrated power management solution. It is ideal for use in battery management systems and can be used in a wide range of applications, from consumer electronics to automotive systems. The integrated power management controller provides fully configurable control, and the integrated safety features further enhance product life and reliability. The PI3USB9281XWEX provides a wide range of I/O, PWM and ISRC programmable outputs and inputs, LED driver control, LED dimming control and LED strobing control, as well as embedded temperature sensing and low power shutdown.
