Principaux différenciateurs
- Higher output current (12A) compared to VNHD7008AYTR (vs VNHD7008AYTR)
- AEC-Q100 qualified for automotive use (vs LTC2944-1)
- Low ON-resistance (25 mOhm) for high efficiency (vs L6470)
Notes de conception
The VNHD7012AYTR can dissipate significant power at high currents. With a thermal resistance of 30 C/W, a 12A load at 28V could generate substantial heat. Ensure adequate PCB copper area, preferably with a thermal pad connected to a large ground plane, to keep the junction temperature within limits. Consider using thermal vias to enhance heat transfer to inner layers.
Place decoupling capacitors (e.g., 100nF and 10uF) close to the VS and GND pins to minimize voltage transients during switching. The current sense pin should be connected to a low-value sense resistor (e.g., 0.1 ohm) with Kelvin connections for accurate current monitoring. Keep the PWM and logic input traces short and away from high-current paths to reduce noise.
Do not exceed the absolute maximum supply voltage of 28V. Ensure the motor's back-EMF does not cause the supply voltage to spike above this limit; use appropriate snubber circuits or TVS diodes. Also, avoid enabling the device without a motor connected, as this may trigger overcurrent protection. Always verify the logic input levels are within the specified range to prevent undefined states.
