NOTES :
1. It is not recommended to short the motor to Vbat. If in this mode an overvoltage condition occured, this would damaged the DHSB.
2.Once the overvoltage condition or undervoltage condition is removed, the H-Bridge recovers its normal operation mode.
3.When the thermal shutdown is reached on one of the High Side MOSFET, both half bridges are turned off with the motor tied to ground. When the overtemperature
condition is finished, the H-bridge recover it previous normal operation mode.
4. The High Side MOSFET HSx which experienced an overcurrent is latched off.The corresponding output OUTx is open. Once the High Side overcurrent condition
is removed, the input INx has to to be reset in order to recover the normal operation mode.
5. When a short to Vbat of one of the Low sides occurs, both outputs are opened to prevent the motor from running. Once the Low side overcurrent is removed, the
input INx of the half bridge wich experienced the fault has to be reset in order to recover the normal operation mode.
