What are the key features of VNH5019A-E?
- 30 A continuous and 60 A peak output current capability drives large brushed DC motors directly from a microcontroller PWM signal without external transistors
- Built-in diagnostics including overcurrent, thermal shutdown, and undervoltage lockout provide robust system-level protection in automotive motor drive designs
- Full H-bridge topology with separate high-side and low-side inputs enables precise bidirectional speed and direction control via standard 3.3 V or 5 V PWM signals
What is VNH5019A-E used for?
The VNH5019A-E is designed for automotive seat adjusters, power window lifters, and sunroof actuators that require a single-chip full H-bridge capable of handling 30 A from a 12 V car battery. It also serves industrial conveyor systems and robotics platforms where bidirectional brushed DC motor control at up to 41 V is needed with integrated fault diagnostics. Makers and engineers use it in high-current motor shield designs for platforms such as Arduino due to its simple PWM interface and robust protection features.

Frequently Asked Questions
What is the maximum continuous current the VNH5019A-E can supply to a brushed DC motor?
The VNH5019A-E delivers up to 30 A continuous output current and 60 A peak current, making it capable of driving large brushed DC motors found in automotive seat actuators, power windows, and heavy-duty robotic joints. The integrated power MOSFETs handle this current directly, eliminating the need for external switching transistors.
Which supply voltage range does the VNH5019A-E support, and does it cover both 12 V automotive and 24 V industrial systems?
The VNH5019A-E operates from a supply voltage of 5.5 V to 41 V. This range covers 12 V automotive batteries (including cold-crank transients up to about 36 V), 24 V industrial DC buses, and 28 V military-grade vehicle platforms, making it a versatile single-chip H-bridge solution across multiple application voltages.
How do the built-in protection features of the VNH5019A-E prevent damage in automotive motor drive circuits?
The VNH5019A-E integrates thermal shutdown (activating at approximately 170°C junction temperature), overcurrent limiting that clamps output current during stall conditions, and undervoltage lockout that disables the bridge when supply drops below 5.5 V. These 3 protection layers prevent MOSFET damage from locked-rotor stalls, load shorts, and battery brown-out events that commonly occur in automotive environments.
How does the VNH5019A-E compare to discrete H-bridge implementations for a 12 V, 20 A motor driver in a compact PCB?
A discrete 4-MOSFET H-bridge for 20 A at 12 V requires at least 4 power transistors, 2 gate drivers, 8 bootstrap and gate resistors, plus current-sense and protection circuitry — easily 30 or more components. The VNH5019A-E consolidates all of this into a single 30-pin PowerSO package under 15 mm × 10 mm, reducing assembly complexity and improving reliability for volume automotive production.
