DRV8313PWPR - 2.5A Triple 1/2-H Bridge Driver | TI
MPN: DRV8313PWPR ✓ Hoạt độngDRV8313PWPR Tóm tắt
A motor driver is an integrated circuit that translates low-power control signals from a microcontroller into the higher voltage and current needed to drive a motor. The DRV8313PWPR is a triple 1/2-H bridge driver, meaning it contains three independent half-bridge outputs, each capable of sourcing or sinking current. This configuration is ideal for driving three-phase brushless-DC motors, where each phase is connected to one half-bridge. The device also supports independent control of each half-bridge, allowing it to drive solenoids, relays, or other loads.
Key features of the DRV8313PWPR include a wide operating voltage range of 8V to 60V, low on-resistance MOSFETs for high efficiency, and overcurrent, overtemperature, and undervoltage lockout protection. The device also features a low-power sleep mode to reduce quiescent current when the motor is not running. These features make it a robust choice for demanding motor control applications.
The DRV8313PWPR uses a simple PWM interface, allowing direct connection to a microcontroller's PWM outputs. Each half-bridge can be controlled independently, enabling flexible motor control schemes such as trapezoidal or sinusoidal commutation. The device also includes a current-sense output that can be used for closed-loop current control, enhancing system performance.
Typical applications include three-phase brushless-DC motor drives for fans, pumps, and robotics, as well as solenoid drivers and other inductive loads. The wide voltage range and high current capability make it suitable for both 12V and 24V systems, common in industrial and automotive environments.
When designing with the DRV8313PWPR, ensure adequate PCB copper area for heat dissipation, especially at high currents. The exposed thermal pad should be soldered to a large ground plane to improve thermal performance. Additionally, place decoupling capacitors close to the power supply pins to minimize voltage transients.

Ghi chú thiết kế
The DRV8313PWPR can dissipate significant power at high currents. The HTSSOP-28 package has an exposed thermal pad that must be soldered to a large ground plane. For continuous operation at 2.5A per channel, ensure the PCB has adequate copper area and vias to conduct heat away. Consider using thermal vias under the pad to improve heat transfer to inner layers.
Place a 0.1uF ceramic capacitor close to each VM pin and a 10uF bulk capacitor near the VM supply. The charge pump capacitor (VCP) should be placed close to the VCP pin. Keep the high-current output traces short and wide to minimize inductance and resistance. Separate the power ground and signal ground to reduce noise.
Do not exceed the absolute maximum supply voltage of 60V. Ensure the SLEEP pin is pulled high for normal operation; leaving it floating may cause unpredictable behavior. The current sense output is a voltage proportional to the load current; use it with an ADC for closed-loop control. Avoid switching the outputs while the motor is spinning at high speed without proper freewheeling diodes.
