Sir,
By feedback I meant the tacho feedback using Op-Amp as shown in the circuit.
My circuit doesn't have op-amp circuitary, rather directly an analog voltage is supplied to the Vref pin.
The motor driver is heating up very much.
I tested the circuit removing Cin as well, still the IC heats up rapidly. The typical current consumed by the IC is 0.7 A and it start increasing. After reaching 0.9 A, the DIAG voltage starts to fluctuate between 5V and 0V.
Please help.
If something is wrong with the implementation of the circuit, please do tell.
Thanks.
