Hi, everybody,I am going to use the ADN8831 to control the DFB Laser temperture,and I have a question need you to help me to solve,which is the H Bridge driver circuit that make up of the mosfet.
As you know, H Bridge driver circuit has the positive and negative deriction to drive the TEC in turn,the P-mosfet and the N-mosfet are controlled by the output of PWM and Linear AMP ,but the problem is when the circuit change the state from the positive to negative deriction,there is a dead zone exist in seconds(maybe decide by mosfet),if I want to eliminate this phenomenon,what I should do?Could you suggest some nice ways improve or solve the issue?Besides,if I replace the mosfet by the NPN transistor which controlled by the linear AMP part,is it will be better than the mosfet? Look forward to your reply,thanks!
