Other Parts Discussed in Thread: SN6501
We are looking for a gate driver for a thermoelectric cooling (TEC / Peltier).
By means of a power source we operate a Peltier.
Switching between heating and cooling is done by a bridge circuit.
We are looking for a half or full bridge driver that can be operated statically.
The boost capacity for the HighSide-FET should be recharged independently without the load being disconnected for a short time.
Are there such gate drivers, and what would be the keyword to limit the search.
Currently we are using the LM5109B from TI, but this IC also has to hang the load for a short time to reload the boost capacity, which in turn disturbs the control loop of the power source.
Attached the schematics of our current design.
Application:
TEC cooling / heating by power source
24V DC / 3A
I would be pleased about a feedback.
