Pierre's 170W in 1600W out Looped Very impressive Build continued & moderated

Here is a half bridge driver for N channel MOSFET's up to 60VDC rail.
It has shoot through prevention under voltage lockout.

If you leave both inputs low  both upper and lower MOSFET will be off.

PDIP package only so unless making a PCB you would have to solder on a DIL header.

$5

Fr. Voici un driver demi-pont pour le MOSFET à canal N jusqu'à 60VDC.
Il a tiré à travers la prévention sous le verrouillage de tension.
Si vous laissez les deux entrées faibles, les MOSFET supérieur et inférieur seront désactivés.
Paquet PDIP seulement donc à moins de faire un PCB vous auriez à souder sur un en-tête DIL.
$5.

Thanks L192 for all these additional options.
But can you help me out with my present build with the questions I PM you hours ago?

Thanks for your help

Hi Gotoluc,

Pretty late here so here is a quick and dirty markup.

5V regulator powers logic side of L298N

You can feed in 35V but the regulator would get very hot so I would use +12V.

The diodes for the transistors are in place on the board.

I have shown connections for Pierres ladder switch arrangement, so the switches are connected in parallel  for a half bridge with a 3.5A rating instead of 2A.

The enable lines switch off both transistors. When enabled the In1 In2 lines are tied together high or low TTL on this input will switch on either the upper or lower transistor pairs.

Regards
