If you're working on a project that involves driving high-current brushed DC motors, you've probably realized that not all motor driver chips are created equal. Some can handle only a few amps of continuous current, while others can handle tens or hundreds of amps—but often at the cost of higher complexity and cost.

Enter the EVAL-VNH5019-P1 from STMicroelectronics. This motor driver IC is designed to provide a balance between ease of use, flexibility, and performance, making it a popular choice for a wide range of applications, from robotics and automation to electric vehicles and industrial machinery.

Key Features and Specifications

The EVAL-VNH5019-P1 is a single-channel H-bridge motor driver that supports continuous currents up to 30A and peak currents up to 50A. It can work with supply voltages from 5V to 36V, and its built-in protection features (such as overcurrent, overtemperature, and undervoltage lockout) help ensure safe operation even in challenging environments.

The driver uses a standard PWM (pulse-width modulation) control scheme, with a frequency range of 20kHz to 100kHz. It has a low-side on-resistance of 19.5mOhm and a high-side on-resistance of 13.5mOhm, which contributes to its low power dissipation and high efficiency.

The EVAL-VNH5019-P1 also includes several useful features, such as:

Current sensing output for closed-loop control

Brake function for rapid motor stop

Direction and enable inputs

Fault status output

Thermal shutdown protection
