Driving Peltier element through L298

Posted on September 10, 2013 at 11:25

Hi,

I want to drive peltier element to control temperature of one module. Peltier specifications are:

Imax = 9A and Vmax = 3.75V.

Such 4 peltiers are connected in series to control to module temperature.

I am planning to use L298N for driving it. As shown if I connect L298N two pins in series then I will be able to drive current upto 4A. But, to control my module temperature, Peltier is sinking average 4A current.

So, It I can't use single L298N IC as it will heat too much and also it will damage.

So, I want to know whether it is possible to use two L298N ICs in parallel to give higher current.

If so then please advice me for input and output pin connections.

Thanks & Regards,
