Description
This module is a compact breakout board for ST's high-power VNH5019 motor driver IC, a fully integrated H-bridge that can be used for bidirectional speed control of a single brushed DC motor.
The basic functionality of the driver is summarized below; however, we recommend carefully reading the VNH5019 datasheet before using this product. The board includes most of the components of the typical application circuit on page 14 of the VNH5019 datasheet, including pull-up and current-limiting resistors, and a FET for reverse polarity protection.
It is delivered fully assembled with SMD components, including the VNH5019, as shown in the product image.
Features:
- Operating voltage: 5.5 – 24 V1
- Output current: 12 A continuous (30 A max)
- 3 V-compatible inputs
- PWM operation up to 20 kHz, which is in the ultrasonic range and allows for quieter motor operation
- Current sense output proportional to motor current (approx. 140 mV/A)
Motor indicator LEDs (show the status of the outputs even when no motor is connected)

- Reverse polarity protection
- Withstands input voltages of up to 41 V
- Undervoltage and overvoltage shutdown
- Thermal shutdown on the high-side and low-side
- Short-circuit protection against ground and against Vcc
- Reverse polarity protection
