Product description: Pololu VNH5019 - Single channel 24 V / 12 A motor controller

ST's VNH3SP30 single-channel H-bridge module allows you to control motors supplied with a voltage range of 5.5 V - 24 V with a continuous current of up to 12 A, instantaneous up to 30 A. The system allows you to change the direction of rotation of the motor and speed control by PWM signal.

Minimal connection of VNH5019 module with microcontroller.

VNH5019 controller specifications

  • Supply voltages: 5.5 V - 24 V
  • Continuous output current: 12 A
  • Maximum instantaneous current: 30 A
  • PWM frequency: up to 20 kHz
  • Current measurement output
  • LED indicators
  • Protection
    • Against incorrect power supply connection
    • Supply voltage too high and too low
    • Against short-circuit to ground and supply voltage

Included:

  • module with VNH5019 controller
  • power supply connector
  • goldpin connector

PWM signal inputs are connected to ground. Therefore the motor power outputs are disabled by default. On the outputs of INA, INB direction of rotation control no potential is set by default.

The LEDs on the board are very helpful in detecting connection problems. The brightness increases with the speed of the motor and the color changes with the direction of rotation.

Pin Description
VIN 24 V power supply
VDD Power supply for logic part 2,5 V to 5 V
VOUT Voltage output after reverse power protection circuit.
OUTA Output of half-bridge A of the motor supply
OUTB Output of half bridge B of motor supply
PWM PWM signal input pulled to ground by default (up to 20 kHz)
INA/INB Inputs for changing the direction of rotation. Not connected by default.
GND GND
CS Current measurement outputs. 140mV per 1A. Active when CS_DIS pin is in low state.
ENA/DIAGA Blocking half-bridge A. Low state blocks the operation of half-bridge A. Default state high.
ENB/DIAGB Half bridge B inhibit. A low state blocks the operation of half bridge B. Default state is high.
CS_DIS Locks the current measurement output. A high state blocks the CS output. Default state low.
