Can I drive external MOSFETS with 12V supply? The ADN8831 drives one half of
the bridge in PWM mode, but the other half is used as the output stage of a
linear amplifier, so presumably, these FETs are driven as source followers (see
last page or two of data sheet for details). I am planning to level convert the
gate drive.


ADN8831 is a 5V device. By itself, there is no way to drive a 12V external TEC
module directly.
Some of our customers used our ADN8831, with external proper level and timing
adjustment, they successed to drive 12V TEC module. Unfortunately in these
cases, without the necessary engineering support, we have no such confirmed
applications circuit suggestion yet.
