ZXBM1004Q16TC Integrated Circuits (ICs)

PMIC - Motor Drivers, Controllers

The ZXBM1004Q16TC is an integrated power management integrated circuit (PMIC) designed to drive and control a brushless DC motor (BLDC). It integrates a controller, three low-side Gate Drivers, one high-side Gate Driver and several current sensing circuits. The device is specifically designed for automotive and industrial applications requiring wide operating temperature range and capability in supplying medium power motor control.

Application Field

The ZXBM1004Q16TC is suitable for a wide variety of applications. It is widely used for driving brushless DC motors and other application including air-conditioning fans, automotive blower systems, power steering pumps, compressor pumps, electric water pump, and robotic actuators. It is also used in industrial automation and robotic arm applications.

Working Principle

The ZXBM1004Q16TC integrated circuit (IC) operates based on the principle of varying current intensity through a series of coils positioned around the motor. This is a form of electrical commutation which produces motion in the electromechanical system. The coil portion of the circuit is referred to as the stator, while the portion of the circuit containing the permanent magnets is referred to as the rotor.

The ZXBM1004Q16TC is an integrated circuit that is capable of controlling the current intensity in the stator coil as well as timing of the switching of the current for each stator coil. This is done by turning off selected stator coil circuits and turning others on with the appropriate phase to keep the motor spinning. The IC also provides feedback from the current sensing circuits to control the current intensity in the coils and to adjust the speed of the motor.

In addition to providing motor control, the ZXBM1004Q16TC also provides motor protection features. These features help guard against conditions such as over-voltage, over-temperature, short circuits, and under-voltage. The ZXBM1004Q16TC also provides Fault Re-Set and Auto-Restart functions which help bring the motor back online in case of a power failure.

Conclusion

The ZXBM1004Q16TC is an integrated power management integrated circuit (PMIC) designed to drive and control a brushless DC motor (BLDC). It is specifically designed for automotive and industrial applications requiring wide operating temperature range and capability in supplying medium power motor control. It operates based on the principle of varying current intensity through a series of coils positioned around the motor for motor control and also provides motor protection features.
