5.7 Current Sense Amplifier (CSA)
(Submit Feedback)The ATA6847 provides three fully integrated operational amplifiers, tailored for measuring power stage currents by sensing currents across the shunt resistors. The gain and output offset voltage are configurable by setting the corresponding bits in the CSCR register via the SPI interface.
Optionally, the CSAs can be disabled.
The CSA output voltage range is adapted to the VIO voltage.
The CSA3 output voltage can be monitored with the ILim module, see OUTPUT CURRENT LIMITATION.
