Hi Motor Hardware Guru's,
I am contemplating adding a mode that holds the low-side FETs ON when the motor drive is idle (sometimes for months) Is there a mode whereby GLSx / low side FET outputs can be set to high or high impedance state in standby or unpowered modes?
The 22K resistor (R21) on the EVAL board suggests there's a need to guarantee OFF state when GLSx is high impedance, but can find no reference to such mode in the datasheet.
Have I missed something obvious or can you describe a method to hold on the low side FETs without impacting battery life too much.
