It's part of [JM's] post about the in's and out's of building microcontroller friendly motor controllers (translated). Then you have to connect 12V to Vcc2 and 5V to Vcc1 pin and the ground of both supplies should be common. in the U.S. Report comment Reply Jan says: October 28, 2011 at 12:43 pm What do you mean with "the MOSFET used on the ground-side of the motor doesn’t actually need to be there" useful reference
TiN_redmc liked AVR Watch. Each output driver channel consists of N-channel power MOSFETs configured in a half-H-bridge configuration. Both L293 and L293D are designed to drive inductive loads such as solenoids, relays, dc motors, bipolar stepper motors and other high current or voltage applications. A further variation is the half-controlled bridge, where the low-side switching device on one side of the bridge, and the high-side switching device on the opposite side of the bridge, are https://en.wikipedia.org/wiki/H_bridge
L293d H Bridge
It is intended to drive a three-phase brushless dc motor, though it can also be used to drive solenoids or other loads. Without it, the motor will keep turning under its own momentum when the half-bridge is shut off. Alternatively, a switched-mode DC–DC converter can be used to provide isolated ('floating') supplies to the gate drive circuitry. With the proper data inputs, each pair of drivers form a full-H (or bridge) reversible drive suitable for solenoid or motor applications.

Logic HIGH at EN1,2 pin enables the drivers 1 and 2. http://enterprisesecurityblog.com/h-bridge/half-h-bridge-driver-circuit.php The design of the transformer is also very important, as the leakage inductance should be minimized, or cross conduction may occur. L293D can provide currents up to 600mA and L293 can provide currents up to 1A at voltages ranging from 4.5 to 36. The L293 and L293D are characterized for operation from 0°C to 70°C.

A multiple-output flyback converter is well-suited to this application. This can extend the relay life, as the relay will be switched while the transistor is off and thereby there is no current flow.

The DRV8313 can supply up to 2.5A peak or 1.75A RMS output current per channel (with proper PCB heatsinking at 24V and 25°C) per half-H-bridge. L298n Dual H Bridge Such a configuration is called a "half bridge". The half bridge is used in some switched-mode power supplies that use synchronous rectifiers and in switching amplifiers.

Many integrated circuit MOSFET gate drivers include a charge pump within the device to achieve this. For a purely inductive load, the current waveform would be a triangle wave, with its peak depending on the inductance, switching frequency, and input voltage. An H bridge is built with four switches (solid-state or mechanical). Do not show again and take me directly to the Basket.
