Power Management (PMIC) products provide designers with the ability to adjust and monitor the power circulation of the system, thereby providing solutions for batteries, power distribution, power sequencing and protection, multiple components with varying power demands, and more. PMIC solutions range from motor drivers and controllers to linear voltage regulators, DC/DC converters, power FETs, and energy harvesting solutions.

The A3992SLPTR-T, a three-phase, brushless DC motor driver, falls under the PMIC motor drivers and controller category. Specifically, this PMIC solution offers a range of features and benefits for BLDC motor designs. This piece offers a broad current control capability, a wide input voltage range, and a simple step-by-step speed control interface. These features allow for the development of applications characterized by reliable and precise motion control for BLDC motor designs.

Features and Benefits

The A3992SLPTR-T incorporates a number of unique and innovative design techniques, making it an ideal solution for numerous applications. It includes a 3-A gate driver output stage, an adjustable current limit, over-voltage protection, an overtemperature protection feature, and a fault reset mode. These combined features provide excellent protection and safety of the motor, as well as exceptional motor performance.

The A3992SLPTR-T also integrates an actual motor load current feedback with an over-current protection feature. This feedback is used to monitor and control the load current within the motion system. This results in a more efficient drive performance and more reliable operation.

Applications

The A3992SLPTR-T can be used in a variety of applications, such as industrial automation, home appliance, pneumatic actuator motors, and 3-phase brushless DC motors used in robotics and sensors. This PMIC can also be used in lighting and HVAC (heating, ventilation and air conditioning) systems, as well as automated gates, printing, and embedded systems.

Working Principle

The A3992SLPTR-T is based on the classic three-phase sinusoidal drive principle. This three-phase motor driver system requires three MOSFETs to be driven separately. In order to achieve linear and precise control, the motor driver should apply the appropriate voltages to each MOSFET of the motor drive.

The A3992SLPTR-T includes a three-phase PWM control, separate current sense resistance for each channel, an over-voltage protection, and an overtemperature protection feature. The three-phase PWM feature facilitates an accurate, precise and dynamic control of the BLDC motor under specified conditions.

The separate current sense for each channel helps accurately measure the current being delivered to the load. The A3992SLPTR-T uses a self-balance current flow to provide constant current across all three MOSFETs. The commutation process can be triggered via discrete logic pins or via digital PWM pins.

The A3992SLPTR-T also includes an over-voltage protection feature. This feature prevents the motor driver from delivering peak voltages that could potentially damage the motor. In addition, the overtemperature protection feature safeguards the motor driver from excessive temperatures in order to protect the motor.

Conclusion

The A3992SLPTR-T motor driver is a powerful feature-packed PMIC solution that offers a range of unique and innovative design techniques. It includes a 3-A gate driver output stage, an adjustable current limit, over-voltage protection, and an overtemperature protection feature. In addition, it provides three-phase PWM control, separate current sense resistance for each channel, and self-balancing current flow for constant current delivery. The A3992SLPTR-T can be used in a variety of applications, including industrial automation, home appliance, pneumatic actuator motors, 3-phase brushless DC motors, lighting and HVAC systems, automated gates, printing, and embedded systems.
