7.3.5.1 SO Sample and Hold Operation
The DRV8703D-Q1 device allows the shunt amplifier to operate in a sample and hold configuration. To enable
this mode, set the SH_EN bit high through the SPI. In this mode, the shunt amplifier output is disabled to the
Hi-Z state whenever the driver is in a brake mode. Place an external capacitor on this pin.
