Key Differentiators
- AEC-Q100 qualified for automotive reliability (vs VNH7100BAS)
- Tape and reel packaging for automated assembly (vs VNH7100BAS)
- Low on-resistance of 60 mOhm (vs VNH7100BAS)
Design Notes
At 12A continuous current, the power dissipation in the VNH7100BASTR can be significant. With an on-resistance of 60 mOhm per switch, the total power loss is approximately I^2 * R = 12^2 * 0.06 = 8.64W when both switches are conducting. The PowerSSO-16 package has a thermal resistance of about 40Β°C/W (junction-to-ambient) with proper PCB layout. To keep the junction temperature below 150Β°C, the ambient temperature must be limited to 150 - (8.64 * 40) = -195.6Β°C, which is impossible. Therefore, a heatsink or a large copper area is mandatory. Use a thermal via array under the exposed pad and connect it to a large ground plane. For typical applications with lower average current, ensure the average power dissipation is within the package's capability.
Place a 100nF ceramic capacitor as close as possible to the VCC and GND pins for logic supply decoupling. For the motor supply (VS), use a bulk capacitor (e.g., 100uF electrolytic) and a 100nF ceramic capacitor in parallel, placed near the VS pins. The exposed pad must be soldered to the PCB with a thermal via array to improve heat dissipation. Ensure the PCB traces for OUT1 and OUT2 are wide enough to handle the 12A current; use at least 2mm width for 1oz copper, or use copper pours. Keep the PWM and control signal traces short and away from high-current paths to avoid noise coupling.
Do not exceed the absolute maximum ratings, especially the supply voltage of 28V. Ensure the motor's back-EMF does not cause the voltage at OUT1/OUT2 to exceed the absolute maximum ratings; use freewheeling diodes or the integrated protection. The PWM frequency should not exceed 20 kHz to avoid excessive switching losses. When using the diagnostic output, note that it is an open-drain output and requires a pull-up resistor. Also, ensure the logic supply (VCC) is within the specified range (typically 3.3V to 5V) to avoid undervoltage lockout.
