VNH5180A-E Présentation
An H-bridge motor driver is a power management IC that controls the direction and speed of a DC motor by selectively switching four transistors in an H configuration. It allows bidirectional current flow through the motor, enabling forward, reverse, and braking operations. The VNH5180A-E integrates the power stage, gate drivers, and protection circuitry into a single package, simplifying PCB design and reducing component count compared to discrete implementations.
Key features include a low on-resistance of 20 mOhm per switch, which minimizes power losses and heat generation at high currents. The device provides a PWM frequency range up to 20 kHz, allowing precise speed control. It includes comprehensive protection features such as undervoltage lockout, overvoltage clamp, thermal shutdown, and load current limitation. The VNH5180A-E also features a diagnostic output that reports fault conditions, enhancing system reliability.
The VNH5180A-E utilizes a proprietary VIPower M0-5 technology, which integrates the power MOSFETs and control logic on a single die. This architecture ensures fast switching and robust operation under harsh automotive conditions. The device is AEC-Q100 qualified, meeting the stringent reliability requirements for automotive applications. Its 16-pin PowerSSO-36 package provides excellent thermal performance with a junction-to-ambient thermal resistance of 30 C/W, allowing operation at high ambient temperatures with appropriate PCB copper area.
Typical applications include automotive power windows, seat adjusters, wiper motors, and industrial automation systems. The device's high current capability and robust protection make it ideal for driving large brushed DC motors in electric power steering (EPS) and engine cooling fans. In automotive body control modules, the VNH5180A-E simplifies motor control by integrating all necessary functions, reducing board space and improving reliability.
When designing with the VNH5180A-E, ensure adequate PCB copper area for heat dissipation, especially at continuous currents above 20A. The PWM input should be driven with a proper dead-time to prevent shoot-through. The diagnostic output can be monitored by a microcontroller to detect faults and implement safe shutdown procedures.

Principaux différenciateurs
- Higher output current (41A) compared to VNH5180A (30A) (vs VNH5180A)
- Lower on-resistance (20 mOhm) compared to MC33932 (55 mOhm) (vs MC33932)
- Higher PWM frequency (20 kHz) compared to MC33932 (11 kHz) (vs MC33932)
Notes de conception
At continuous currents above 20A, ensure adequate PCB copper area for heat dissipation. The PowerSSO-36 package has a junction-to-ambient thermal resistance of 30 C/W. For a 41A load with a 12V supply, power dissipation can be significant, so use a large copper pour and consider a heatsink if ambient temperatures are high.
Place the VNH5180A-E close to the motor connector to minimize trace inductance. Use wide, short traces for the high-current paths (OUT1, OUT2, VCC, GND) to reduce resistance and inductance. Add bulk and ceramic capacitors near the VCC pin to handle current transients.
Ensure proper dead-time in the PWM signal to prevent shoot-through in the H-bridge. The diagnostic output should be monitored by the microcontroller to detect faults and implement safe shutdown. Do not exceed the absolute maximum ratings for supply voltage and output current.
