BCM85625IFSBG

BCM85625IFSBG is an integrated silicon CMOS solenoid driver for brushless DC motor control applications. It is an innovative solution for motors that require a fast reaction to changes in the environment and as such is an ideal choice for the application of high speed, low noise, high efficiency motors and fans. The integrated digital driver enables the motor to react quickly to changes in the environment, improving performance and power savings.

Application:

The BCM85625IFSBG is a highly reliable integrated CMOS driver for brushless DC (BLDC) motors. The high speed and accuracy of the solid-state driver enables synchronous, asynchronous, and brushless DC motors to operate with optimal performance. The integrated motor driver supports a wide variety of motors (including fans, pumps, and compressors) requiring automation and high speed, low noise, and high efficiency. It is suitable for applications such as air conditioning systems, refrigerators, water heaters, dishwashers, washing machines, and industrial machinery.

Working principle:

The integrated design of the BCM85625IFSBG driver is based on a three-phase brushless DC motor control system. It is built using a three-phase bridge-driver circuit, which uses six high-side reduced-side drivers, three high-side drivers, and three low-side drivers to drive the three phases in the motor winding. The driver uses an innovative digital control system to control the bridge-driver circuit, providing precise control of the motor winding currents and voltages. The motor controller includes a built-in PWM generator, which generates the necessary control pulses for each phase to drive the motor winding. The PWM generator combines with the bridge-driver circuit to control the speed and direction of the motor winding.

The BCM85625IFSBG digital control system also has three logic inputs (2DU, 2EN, and RST) for inputting control signals. These signals control the power supply, the logic of the bridge-driver circuit, and the pulse signal to the motor winding. Through these control signals, the user can control the motor speed, direction, and set the initial position of the motor. The motor controller also has built-in transistors to protect the motor from overcurrent, overvoltage, and thermal overload conditions, providing a highly reliable and efficient solution for brushless DC motor control applications.
