Hello,

My need is to drive an heat resistor of 2.4 ohm under 29V (about ~12A)

Currently, Im using a gate driver of type IRS2117 and a Canal-N MOS to have a low RDSOn (CDS18537) because the resistor have the common to GND.

Then We have to drive the resistor through the 29V.

Due to Canal-N, I must use a gate driver and make a 15V floatting power.. THis is not cost efficient.

Bellow is a schematic that I'm looking for:

Is somebody can indicate me if only one integrated component can answer to my need, and the main criteria is that component is available on provider, not out of stock...

 

Thank

thank for this feedback.

 

But the presented chip are on 12V (vs 29V at least needed)

Also, there are not available on main provider.

Regards

Although they are from classic profet 12V family, the maximum operating voltage is 38V for both parts (5.4.1 on page 13 in datasheets). By clicking the Buy Online button on product pages you can find they are available in some main distis like AVNET and mouser.
