VNH5019 - 30A Automotive H-Bridge Motor Driver | STMicroelectronics
MPN: VNH5019 ✓ Hoạt độngVNH5019 Tóm tắt
An H-bridge motor driver is a power management IC that allows a DC motor to be driven in both directions (forward and reverse) by controlling the polarity of the voltage applied across the motor terminals. It sits between a microcontroller and the motor, translating low-power logic signals into high-current switching actions. The VNH5019 belongs to the broader category of motor drivers, which are essential in robotics, automotive, and industrial automation systems where precise speed and direction control are required.
Key features of the VNH5019 include a wide operating voltage range of 5.5V to 24V, a continuous output current of 12A with a peak capability of 30A, and an ultra-low on-resistance of 18mOhm per switch. The device supports PWM frequencies up to 20kHz (ultrasonic), enabling silent motor operation. It also provides a current sense output that delivers an analog voltage proportional to the motor current, facilitating closed-loop control and overcurrent monitoring.
The VNH5019 integrates comprehensive protection features, including reverse-voltage protection, over-voltage protection, under-voltage lockout, overcurrent protection, and thermal shutdown. These protections ensure robust operation in harsh automotive and industrial environments. The device operates with logic levels from 2.5V to 5V, making it compatible with both 3.3V and 5V microcontrollers. The MultiPowerSO-30 package provides excellent thermal performance, with a junction-to-ambient thermal resistance of C/W, allowing continuous operation at high currents with appropriate PCB copper area.
Typical applications include automotive power windows, seat adjusters, and wiper motors, as well as robotics, automated guided vehicles (AGVs), and industrial actuators. The VNH5019 is also widely used in educational robotics platforms and hobbyist motor driver carriers, such as those from Pololu. Its combination of high current capability, integrated protection, and ease of use makes it a preferred choice for designers requiring a reliable, compact H-bridge solution.
When designing with the VNH5019, ensure adequate PCB copper area for thermal dissipation, especially when operating at continuous currents above 6A. The current sense output should be connected to an analog-to-digital converter (ADC) input for accurate motor current monitoring. Additionally, proper decoupling capacitors (e.g., 100nF ceramic and 10uF electrolytic) should be placed close to the VCC and GND pins to suppress voltage transients during PWM switching.

Ghi chú thiết kế
The VNH5019 can dissipate significant power at high currents. For example, at 12A continuous current and 18mOhm on-resistance, the power dissipation is approximately 2.6W per switch. Ensure adequate PCB copper area (at least 2 square inches) and consider using thermal vias to improve heat dissipation. The MultiPowerSO-30 package has an exposed pad that should be soldered to a large copper pour for optimal thermal performance.
Place 100nF ceramic capacitors close to the VCC and VS pins for high-frequency decoupling. Additionally, use a 10uF electrolytic capacitor on the VS pin to handle current transients during PWM switching. Keep the motor supply traces short and wide to minimize inductance and voltage drops. The current sense output (CS) should be routed to an ADC input with a low-pass filter (e.g., 1kOhm resistor and 100nF capacitor) to reduce switching noise.
Do not exceed the maximum operating voltage of 24V, as this can damage the driver. Ensure the logic supply (VCC) is within the 2.5V to 5V range; applying higher voltages can damage the input pins. When using the current sense output, note that it provides an analog voltage proportional to motor current, but the exact scaling factor depends on the sense resistor and gain settings - refer to the datasheet for the transfer function. Also, avoid driving the motor with PWM frequencies above 20kHz, as this may cause excessive switching losses.
