Key Differentiators
- Higher continuous current rating (12A) compared to VNH7100ASTR (10A) (vs VNH7100ASTR)
- Wider supply voltage range (4V-28V) compared to VNH5019ATR-E (5.5V-18V) (vs VNH5019ATR-E)
- Lower ON-resistance (25 mOhm) compared to VNH7100ASTR (30 mOhm) (vs VNH7100ASTR)
Design Notes
At 12A continuous current and 28V supply, the power dissipation can be significant. With an ON-resistance of 25 mOhm, the power loss is approximately 3.6W per channel. The PowerSSO-36 package has a thermal resistance of 30 Β°C/W, so a proper PCB copper area (at least 2 square inches) is required to keep the junction temperature below 150Β°C. Use thermal vias to enhance heat transfer to the ground plane.
Place decoupling capacitors (100nF and 10uF) close to the VS and VCC pins to minimize voltage transients during switching. The current sense pin (CS) should be connected to a low-value sense resistor (e.g., 1kOhm) to convert the current signal to a voltage for the microcontroller. Ensure the sense resistor is placed close to the CS pin to reduce noise pickup.
Do not exceed the absolute maximum supply voltage of 28V. Ensure the logic inputs are not left floating; use pull-up or pull-down resistors as needed. The enable pin (EN) must be high for the device to operate. When using PWM, ensure the frequency does not exceed 20 kHz to avoid excessive switching losses. Also, verify that the motor's stall current does not exceed the peak current rating of 20A.
