DRV8801: Fault condition, Rsense, charge pump, thermal pad

Hi TI-forum,

Brush-motor design using DRV8801. Prototypes, hand soldered by skilled personal. UBB=24V, Inom=480mA, Iblock=2A

If Rsense is 120mOhm and a blocked motor cause more than 500mV at SENSE pin, what will happens first, will the device damaged or will the protection stop current flow?

I see some prototypes with nFault=low but functional (UBB=ok). In datasheet block diagram there several abbreviations for fault conditions: abbreviation "STB" and "STG" are for ..?

charge pump: if UBB=24V, what voltage level should VCP and CP1/CP2 go for?

will device be functional if the thermal pad is not connected to GND (pin12/pin2)?

Thanks in common. Holger
