The VNH5019 is ideal for automotive power window systems due to its 12A continuous current capability and 24V operating range. In a typical power window application, the VNH5019 drives a DC motor that moves the window glass up and down. The H-bridge configuration allows bidirectional control, enabling both window raise and lower functions. The integrated reverse-voltage protection and thermal shutdown ensure reliable operation in harsh automotive environments, where voltage transients and temperature extremes are common. The current sense output can be used to detect window stall conditions, allowing the system to stop the motor and prevent damage. Compared to discrete MOSFET H-bridges, the VNH5019 simplifies the design by integrating all protection and control circuitry into a single package, reducing board space and component count.

Key Differentiators
- Higher operating voltage range (24V vs 16V) (vs VNH2SP30)
- Supports 3V logic (vs VNH2SP30)
- Lower on-resistance (18mOhm vs 20mOhm) (vs BTN8982TA)
Design Notes
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.
