A3967SLB-T is an integrated motor driver and controller, which is widely used in a variety of applications due to its compact design, low cost, and excellent performance. This motor driver and controller is designed to drive two brushed DC motors bidirectionally by combining both H-bridge and half-H-bridge drivers.

The A3967SLB-T motor driver and controller is based on the Allegro A3967SLB integrated circuit. The device includes a set of interface logic and independent control circuits for each half-bridge. It also features a separate supply for the H-bridge drivers, allowing for the use of higher voltage supplies for the bridge, while using a lower voltage supply for the logic and on-chip protection features. It features built-in protection against power dissipation, hazardous faults, and over-temperature.

The A3967SLB-T also includes a power stage that is capable of driving up to 2A of continuous load current with microstepping control. It is designed to accept a wide range of input signals, including two-wire control signals, three-wire control signals, PWM signals, and I2C programming. Additionally, it is able to self-detect and automatically configure itself for proper operation when a new PWM signal is connected.

The A3967SLB-T features a single-axis current control circuit that is capable of providing up to 2A continuous load current. It accepts current control inputs from a PWM signal or from an I2C register. The current control circuit comes with adjustable full- and half-wave rectification, an adjustable full-wave rectification frequency, and adjustable current control slew rate.

The A3967SLB-T also features integrated motor protection circuits, which include temperature protection, short-circuit protection, under-voltage protection, overvoltage protection, and over-current protection. When motor conditions exceed the set thresholds, the motor will be shut down to prevent damage.

The A3967SLB-T is packaged in a small 16-pin SOIC package and operates over a wide temperature range. It is an ideal solution for applications such as high-performance robotic arms and automotive electric power steering systems. It is also suitable for controlling a variety of other motors, such as electric fans, electric actuators, and small pumps.

Overall, the A3967SLB-T motor driver and controller is an invaluable addition to any application that requires precise motor control. With its wide range of features and protections, the device is sure to be the perfect choice when it comes to providing reliable and smooth motor operation.
