Application Description:

Power tools are handheld tools powered by small electric motors or electromagnets, driven by transmission mechanisms to operate the working head. They can be classified into three categories based on their electrical protection measures: Class I: In addition to basic insulation, they require protective grounding. Class II: The tools themselves have double insulation or reinforced insulation and do not require grounding. Class III: They are powered by a safe extra-low voltage source, and the internal voltage does not exceed the safe voltage of the power source.

Key components of industrial power tools include MCU, motor, motor driver chips, circuit protection chips, power management chips, ADC chips, switches and connectors, batteries, and charging management chips.

Product Advantages:

Our self-developed BMS chip has been applied in handheld drills. In addition to basic functions such as battery level detection and current monitoring, it also features temperature sensing, temperature alarm, overcurrent protection, charge and discharge protection, simultaneous charging and discharging, and more.

It can communicate with the master device (Master) via I2C, and based on the specific application, parameters can be written to the internal registers through the I2C protocol to achieve different functionalities.
