Key Differentiators
- 8-channel integration in a single PowerSSO-36 package (vs VNQ7004AYTR (4-channel))
- SPI interface for advanced control and diagnostics (vs VNHD7008AYTR (PWM motor driver))
- Low standby current of 5 µA (vs VNQ7004AYTR)
Design Notes
The VNQ7008AYTR has a thermal resistance of 40 °C/W. When driving all 8 channels at 0.7 A each with a supply voltage of 28 V and load voltage of 12 V, the power dissipation per channel is (28-12)*0.7 = 11.2 W, totaling 89.6 W, which is unrealistic. In practice, ensure the total power dissipation does not exceed the package's ability to dissipate heat. Use adequate PCB copper area and consider a heatsink or forced air cooling for high-current applications. The junction temperature must remain below the maximum rating of 150°C.
Place a 100 nF ceramic capacitor close to the VCC pin for decoupling. For each output, consider adding a flyback diode if driving inductive loads, although the device has internal protection. Ensure the exposed pad (if present) is soldered to a large copper area for thermal dissipation. Follow the layout guidelines in the STMicroelectronics datasheet for optimal performance.
Do not exceed the absolute maximum supply voltage of 28 V. Ensure the SPI lines are properly terminated and not left floating. The enable pin (EN) must be pulled to a defined logic level to avoid unintended operation. When using the SPI interface, ensure correct timing and protocol as per the datasheet to avoid communication errors.
