• Screwless row connector pins for external loads switched by low-side or high-side drivers
• Easy adaptation of loads directly on the ATA6826 design kit
• Direct switch of loads to V
• Forward/reverse rotation of DC motors by full-bridge application
• Paralleling of outputs for powerful applications
• PC adaptation via standard “SUB-DE” connectors (plug 4 in
• Input for 5V VCC power supply alternatively on board or external by row connector 2
• Indicate rotation direction of DC motors by LEDs, best function at V
• PC-controlled functions via software user interface
• All pins are easily accessible via test points
• Inhibit switch on board or by external input
