The DRV84xx, DRV89x2, and DRV82x2 family of devices consists of wide voltage, high power drivers ideal for a large range of industrial applications.

DRV84xx: DRV8452, DRV8461, and DRV8462, Stepper Motor Driver with Autotorque, Silent Step Decay Mode, and Automatic Microstepping

The auto-torque feature boosts system efficiency by adjusting the coil current according to the load torque. The standstill power saving mode automatically reduces power loss during motor hold condition. The silent step decay mode enables noiseless operation.

The internal current sense architecture eliminates the need for external sense resistors, therefore saving PCB area and system cost. The built-in indexer of the DRV8452/DRV8461/DRV8462 supports up to 1/256 microstepping, and the automatic microstepping mode interpolates the input STEP signal to reduce overhead on the controller MCU.

Sensorless stall detection eliminates end stops from the system. The device supports protection and diagnostic features for robust and reliable operation.

DRV89x2: DRV8952 and DRV8962, Four-channel Half-Bridge Driver with Current Sense Outputs

The output stage of the device consists of N-channel power MOSFETs configured as four independent half-bridges, charge pump regulator, current sensing and regulation circuits, current proportional outputs and protection circuitry.

Integrated current sensing across the high-side MOSFETs allows the device to regulate the load current when the load is connected from output to ground. A regulation current limit can be set with an adjustable external voltage reference (VREF). Additionally, the device provides four proportional current output pins, one for each half-bridge high-side FET.

A low-power sleep mode is provided to achieve ultra-low quiescent current. Internal protection features are provided for supply under-voltage lockout (UVLO), charge pump under-voltage (CPUV), output over current (OCP), and device over-temperature (OTSD).

DRV82x2: DRV8252 and DRV8262, Single or Dual H-Bridge Motor Drivers with Current Sense Output

The device integrates two H-bridges. The two H-bridges can be paralleled together. Reference the data sheet for more information.

Similar to the DRV89x2, integrated current sensing across the high-side MOSFETs allows the driver to regulate the motor current during start-up and high load events. A current limit can be set with an adjustable external voltage reference. Additionally, the device provides output current proportional to the motor current for each H-bridge. The integrated sensing uses a current mirror architecture, removing the need for large shunt resistors, saving board area and reducing system cost.
