Hi,
Currently looking to use the TPS25980 for protection to one of our motor driver boards
For our application when the system is powered off (TPS252980 in shutdown mode but power still applied to Vin) we allow the users to be able to back drive our motors
Due to this the voltage on VOUT rises until the body diode off the mosfet conducts. Based on some experiments the delta between vin and vout(vout-vin) during shutdown and back driving is 0.6V(assuming this is the forward voltage of the body diode)
In the data sheet it states that vout max is equal to Vin+0.3V. I am wondering is this parameter when the efuse is in the on state?
Do you see this as a concern if we allow the users to backdrive the motors causing the delta between vout and vin to be 0.6V?
Thank you for your help,
Visaacan
