Working Principle

The VN920-12-E is an H-bridge driver, which consists of four field effect transistors (MOSFETs) arranged in a bridge configuration. When the input is driven with a positive signal, the MOSFETs switch on in sequential order and the current flows through the load. When the input is driven with a negative signal, the MOSFETs switch off in sequential order, providing a convenient way to switch the current on and off.

The VN920-12-E can be used to switch currents up to 10A. It is designed to operate with a single supply voltage of 5V. The device has an internal pull-up circuit which eliminates the need to externally provide the pull-up resistors. The device has logic inputs which are used to control the switching speed. It has a built-in over voltage protection which protects against voltage spikes.

The VN920-12-E can be used to switch a variety of loads, from DC motors to relays and solenoid valves. It is also suitable for stepper motor control and for interfacing with a variety of microcontrollers and programmable logic controllers (PLC). The device has a logic output which can be used to indicate if the output is high or low.
