Aptinex Dagaya VNH5019 Dual Motor driver
VNH5019 Based Dual Motor Driver (12A Max per Channel) for Brushed Motors
Dagaya 2.0 makes it easy to control two bidirectional, high-power, brushed DC motors with any microcontroller or any other development board. The board includes 2 robust VNH5019 motor drivers from ST(VNH5019A-E datasheet), which is operating from 5.5 to 24 V and having the capability to deliver a continuous 12 A (30 A peak) per channel.
The VHN5019A-E is a full bridge motor driver intended for a wide range of automotive applications. The device incorporates a dual monolithic high-side drivers and two low-side switches. The high-side driver switch is designed using STMicroelectronics’ well known and proven proprietary VIPower® M0 technology that allows to efficiently integrate on the same die a true motor driver..
